Geared motors can be found in almost every industry. Although there are hundreds of manufacturers that can supply standard and custom geared motors, there are very few suppliers that can provide integrated drive solutions, including planning, system completion, and control of the entire drive chain. In order to provide customers with the perfect drive chain solution plan, Siemens, a reputable supplier of damaged drive systems, has successfully developed a new generation of industrial geared motors after years of efforts. This series of geared motors appeared at the Hannover Messe 2012. In recent years, the energy efficiency of machines and equipment has been closely valued.
In addition to energy efficiency, the precise planning and completion of driving skills resolution programs is also important. Therefore, if you can provide a perfect integrated solution plan that includes the entire drive chain, from the planning and completion of the system until it is handed over, it will be a good path. But integrating components from different manufacturers into the same system is not easy. Now, Siemens has taken a different approach and showed the world a unique and innovative concept: In order to always adhere to the first-class quality, Siemens faced a lot of challenges and integrated perfectly from all stages of Wholesale Purifier motor https://www.chinakxdq.com/product/purifier-motor/ planning and planning to service in the later stages, and continuously Optimize the entire drive chain with the goal of supplying comprehensive product and service solutions across the world. Relying on the successful development of the new generation of Simogear geared motor series that appeared at the Hannover Messe 2012, Siemens once again perfected an important part of the drive chain. By replacing the well-known Motox geared motors, Simogear will bring higher reliability, versatility, sensitivity and richer product areas to equipment manufacturers. Standards and standards plan to facilitate the completion of a perfectly running drive chain will definitely facilitate the loading and unloading of materials in various industries such as automobiles, logistics, food and beverages. Not only help to improve the economic efficiency of the enterprise, but also reduce operating costs, improve system and equipment availability, and service ability. For equipment manufacturers, using the new Siemens Simogear geared motor series means an unprecedented approach to planning. After adopting standard device standards (which can be applied to different center heights, output shafts, feet and flange installations, etc.), Siemens Simogear’s new geared motors support the mainstream mature market planning guidelines. This means that replacing suppliers or finding another supplier to share the risks will become as simple as upgrading or re-planning the existing drive system at a lower cost. In addition to these features, a careful study of the technical details of Simogear geared motors will reveal that compared with other competitors’ products on the market, the functions of this series of geared motors have been significantly improved. For example, in the two-stage transmission helical-bevel gearbox of this new type of reduction motor, the first-stage speed ratio is very large, and its total transmission ratio is between 3.5 and 60.
Because of the special planning, which eliminates a transmission stage, this can be done because Siemens uses a more compact plug-in pinion plan instead of the shaft-mounted pinion plan adopted by many well-known competitors. In this plan, the pinion is not mounted on the motor shaft, but is inserted directly into the motor shaft hole. Therefore, the pinion standard is greatly reduced, and then the speed ratio of the first transmission stage mentioned above is significantly increased. The advantage this brings to equipment manufacturers is obvious: In some cases, the first drive stage can be omitted and the drive power can be increased. Because according to the approximate rule, the power will decrease by 2% for each additional stage. At the same time, because the peripheral speed of the first transmission stage is low, noise and loss due to immersion in the oil are also reduced. In addition, because the first gear stage can be reduced, there are fewer parts in the gear box and the weight of the geared motor is lighter. In addition to the process of developing Simogear geared motors, Siemens has also considered that gearboxes can be equipped with high-power IE2 motors and even higher-power IE3 motors without the need to change the device standard. Therefore, when the power level is increased from IE2 to IE3, there is no need to change the high standard of the motor shaft. For factory manufacturers, this means that motors with power level IE3 can also have a wide range of speed ratios. Because of the use of integrated motor end caps, the structure is more compact. Another highlight of this series of motors is the motor’s integrated end caps, which replaces the standard structure of excessive disk and end caps adopted by other manufacturers. Relying on this plan, the entire new generation of Simogear geared motors reduces the length of the fuselage, and eliminates an interface or sealing surface, and then makes the motor structure more compact and easier to maintain. The same plan is also used for helical-bevel gearboxes, because the pinion shaft uses a new bearing mounting method, which is shorter and lighter. In addition, the planning and improvement of standard components has made the product range of Simogear gear motors more abundant than the previous Motox gear motors. Increasingly subdivided specifications and speed ratio levels can not only improve economic efficiency, but also facilitate equipment manufacturers’ planning of driving solutions. Modular planning, more sensitive In the motor, Simogear adopts Siemens’ patented Modulog modular system planning guidelines. At the center of this modular system is a 2-, 4- or 6-pole basic motor with additional power ranging from 0.09 to 200 kW, suitable for various international power sources. At the end of the motor, a small shaft equipped independently can ensure that the motor flexibly meets the functional requirements: brakes, backstops, encoders and fans can be installed into the motor system through the small shaft device. Its benefit is that this small shaft plan is easier to handle and store than many varieties of rotor shafts. Therefore, the geared motor can be easily equipped according to the requirements of the factory manufacturer, and the delivery cycle is shorter. The choice of material for the gearbox also shows a high emphasis on customer needs. Especially for places with high weight requirements, Siemens can supply a series of low-torque gearboxes and corresponding motors with a completely aluminum casing. In addition, small geared motors of size 29 and below are also equipped with a lifetime smooth system. In order to extend the maintenance period, it is advisable to use component oil as much as possible. First-class software and hardware equipment to create a perfect drive chain. The planning and development engineers of this series of new geared motors attach great importance to the additional torque of the gearbox, the allowable radial force, the output shaft diameter, the bearing life and the gear tooth fatigue strength. Outstanding balance. Now, with a new generation of Simogear gearmotors (which can replace the previous Motox series gearmotors), Siemens has further promoted Siemens’ outstanding image as a perfect system and solution plan partner. In the fully integrated automation system, after Simogear’s new generation of geared motors, Siemens can supply from planning and planning to planning and subsequent services.

Couplings are more common parts in motor systems. Generally, users only choose the corresponding size of the shaft to use according to the shaft diameter of the motor. But in fact, there are several types of couplings. In practice, they must be selected according to different applications. Couplings are classified as follows, mainly divided into two categories: flexible and rigid. First, flexible stove motor manufacturers https://www.chinakxdq.com/product/range-hood-motor-integrated-stove-motor/ couplings. Flexible couplings refer to parts of the couplings that are flexible and deformable. When connecting the two shafts, they are allowed to have a certain amount of rotation Misalignment occurs, that is, the coupling can be deformed under dynamic conditions. 1. Plum blossom coupling Plum blossom coupling is a widely used coupling, also known as claw coupling, which is composed of two metal claw disks and an elastomer. The two metal claw disks are generally 45-gauge steel, but aluminum alloys are also useful when sensitive loads are required. Because the elastic body has the effect of buffering and damping, it is often used in the place with strong vibration. The functional limit temperature of the elastomer determines the operating temperature of the coupling, which is generally -35 to +80 degrees. 2. Elastic post couplings Elastic post couplings are made of a number of non-metallic elastic materials. They are placed in the flange flange holes of the two halves and the two halves are connected through the pins. The shaft has a simple structure and is easy to manufacture. It is more convenient to assemble, disassemble and replace the elastic element without having to move the two couplings. 3. Spring Coupling Coupling Spring Coupling is a kind of corrugated thin-walled tube that is directly welded or bonded to the coupling halves to transmit motion. This type of coupling has a simple structure, small dimensions, convenient processing and installation, and high transmission accuracy. It is mainly used in small power precision machinery and control organizations that require compact structures and high transmission accuracy. 4. Universal joint coupling The universal joint uses its organizational characteristics, so that the two axes are not on the same axis, and the connected two axes can be reversed successively under the condition of the axis angle, and the torque can be reliably transmitted. And exercise. The biggest feature of the universal coupling is that it has a large angular compensation capability and a compact structure, but the transmission power is not very good compared to other couplings. The angle between the two axes of different types of universal joints is different, and is generally between 5 \u0026 deg; -45 \u0026 deg ;. 2. Rigid Couplings Rigid couplings, as the name suggests, are actually a coupling that changes rigidity, and there is no reverse gap even when receiving a load. Even when there is a deviation and a load occurs, the rigid coupling is still Rigid transmission of torque. Small standard rigid couplings have the advantages of light weight, ultra-low inertia and high activity. In practical applications, rigid couplings have the advantages of maintenance-free, super oil resistance and corrosion resistance. 1. Membrane coupling The membrane coupling relies on the elastic deformation of the diaphragm to compensate the relative displacement of the two coupled shafts. It is a high-functional flexible coupling with strong metal elements. It does not require oil lubrication and has a compact structure. High strength, long service life, no rotating space, no influence of temperature and oil pollution, with acid, alkali and corrosion resistance characteristics, suitable for high-speed, high-speed, and corrosive media working environment of the shaft drive. And in terms of its structural characteristics, it has a safety link. When the actual load exceeds the load that was previously restricted, the diaphragm will crack, cut off the movement and power transmission, and then maintain the rest of the machine without damage, resulting in a safe maintenance effect. 2. Flange Flange, also known as flange. The flange is a joint between the shaft and the shaft. Flange connection or flange joint refers to the detachable connection of a group of combined sealing structures, which are connected by flanges, gaskets and bolts to each other. They are often used in high torque transmission situations.
Miniature reduction motor is an independent closed transmission device located between the prime mover and the working machine. It is used to reduce the speed and increase the torque accordingly. Geared motors are mainly divided into two categories: geared motors and worm geared motors. The gear reduction motor is mainly divided into cylindrical gear reduction motor, bevel gear reduction motor, and cone-cylindrical gear reduction motor. The characteristics of gear reducer motor are efficiency and reliability, long working life, easy maintenance and application. The number of stages of the gear reduction motor can be divided into single-stage, two-stage and three-stage gear reduction motors. The installation arrangements of the gear reduction motors mainly include expansion, coaxial and shunt. In the two-stage cylindrical gear reduction motor, the gear is asymmetric with respect to the support position. When the shaft is bent and twisted, the Air conditioning fan motor suppliers https://www.chinakxdq.com/product/air-conditioning-fan-motor/ load is unevenly distributed in the tooth width. Therefore, the shaft should be designed with greater rigidity and the gear should be far away from the input end. Or output. The characteristics of the split type of the two-stage cylindrical gear reducer motor: the position of the extended shaft of the split reducer motor can be extended from any side, which is convenient for the overall configuration of the machine. In order to offset the axial force, one of the shafts should be allowed to move slightly in the axial direction, so as not to jam the gear. The characteristics of coaxial geared motor: compact radial size, but larger axial size. Due to the large intermediate shaft, the shaft has greater disturbance under load, so the load concentration along the tooth width is more serious. At the same time, since the centers of the two-stage gears must be the same, the bearing capacity of the tell-stage gears is difficult to make full use of, and the lubrication of the bearings located in the middle of the reduction is also difficult. The input and output ends of the geared motor are located at both ends of the same axis, which limits the overall configuration of the transmission.
The power (W) of the AC motor and servo motor usually refers to the ’extra speed’ Speed
2020年2月24日Children’s shoes that have been in contact with stepper motors for a long time will definitely find that there is no power in the specifications of stepper motors, and the usual selection is also based on the torque at the corresponding speed. The reason why the power (W) is not marked in the stepper motor specification is because the stepper motor does not have the concept of ’extra speed’. The power (W) of the AC motor and servo motor usually refers to the ’extra speed’ Speed \u0026 rdquo; Power when running (W), ’extra power’. Stepper motors are generally used in a wide range of speed control, its power is changed, the power (W) calculated by substituting different speeds will also The difference is generally only measured by torque.
The formula of torque and power budget is as follows: P = \u0026 omega; \u0026 middot; M \u0026 omega; = 2 \u0026 middot; π; \u0026 middot; n / 60 P = 2 \u0026 middot; π; \u0026 middot; n \u0026 middot; M / 60 = 0.1047 *; n *; M where P is the power unit in watts (w), \u0026 omega; is the angular velocity in radians per second (rad / s), n is the speed per minute (r / min), and M is the unit of torque is Newton \u0026 middot; m (N \u0026 middot; m). P = 2π; fM / 400 (half step operation), where f is the number of pulses per second (PPS for short). Take the stepper motor 24HD240D8 as an example, as shown below: Air conditioning fan motor suppliers https://www.chinakxdq.com/product/air-conditioning-fan-motor/ According to the speed-torque curve It can be seen that when the rotation speed is 600 RPM, the torque is 0.9 Nm. Substituting it into the formula: 0.1047 *; 600 *; 0.9 = 56 .5W (without adding safety factor calculation), that is, when the driver ASD880R is used, the driving voltage is 60VDC, the driving current is 4.0A, and the subdivision setting is 200 pulses / revolution, the mechanical output power of the 24HD240D8 at 600RPM is 56.5W . In practice, we often replace the servo motor with a stepper motor. At this time, we must calculate the torque of the servo output in reverse. The budget formula is as follows: M = 9.549 *; P / n If we want to replace the extra power with a stepper motor 100W, additional speed 3000RPM, deceleration servo motor with a reduction ratio of 10. (assuming that the power of the reducer is 90%) substitute the formula to calculate the additional torque of the motor: 9.549 *; 100/3000 = 0.3183NmN output torque of the reducer shaft: 0.3183 *; 10 *; 90% = 2.8647 Nm Reducer output speed: 3000 \u0026 divide; 10 = 300RPM That is to say, the stepper motor we choose may be a decelerating stepper motor at 300RPM output torque is 2.8647 Nm (without considering the safety factor) can replace this deceleration Servo motor. Without considering the size, the torque of our 3402HS60U14 at 300RPM is 2.95Nm, which can meet the requirements.
The formula of torque and power budget is as follows: P = \u0026 omega; \u0026 middot; M \u0026 omega; = 2 \u0026 middot; π; \u0026 middot; n / 60 P = 2 \u0026 middot; π; \u0026 middot; n \u0026 middot; M / 60 = 0.1047 *; n *; M where P is the power unit in watts (w), \u0026 omega; is the angular velocity in radians per second (rad / s), n is the speed per minute (r / min), and M is the unit of torque is Newton \u0026 middot; m (N \u0026 middot; m).

List of DC motor parameter terms
2020年2月14日List of DC motor parameter terms: 1, Assigned power rating. Nominal power. Or rated power. The ideal power when designing the motor system is also the maximum power under the recommended operating conditions. POWER RATING is power. 2, Nominal voltage. Rated voltage. Or working voltage, recommended voltage. Because general motors can work at different voltages, but the voltage is directly related to the speed, and other parameters also change accordingly, this voltage is only a recommended voltage. Other parameters are also given at this recommended voltage. NOMINAL by name. 3. No load speed.
No-load speed, or no-load speed. The unit is RPM. revolutions per minute R here is not the meaning of RATE speed, but the meaning of REVOLUTION rotation. That is how many revolutions per minute. The no-load speed has no reverse torque, so the output power and stalled condition are different. This parameter only provides a function of the maximum speed of the motor at the specified voltage. Generally, 6000 revolutions, ah, 12000 revolutions are given outside, which refers to this parameter. 4. Stall torque Stall torque. This is an important parameter for many motors with a load. That is, the moment when the motor is stopped by a reverse external force. If the motor stall occurs frequently, it will damage the motor or burn the driver chip. So when you choose the motor, this is the first parameter to consider in addition to the speed. 5, Speed / torque gradient. If the speed is the Y axis and the torque is the X axis, in general, the motor first has a line parallel to the X axis, and then it drops a bit like the negative exponential form of E. That is, the product of speed and torque decreases with increasing torque. Motor manufacturers recommend that the motor be operated within that line parallel to the X axis. In this range, the current of the motor will not cause the motor to overheat and burn. 6. No load current. No-load current. Or idling current. As mentioned earlier, current and torque are closely related. No-load current must exist, and the energy formed by the product of voltage and voltage is mainly divided into potential energy and heat energy consumption.
Thermal energy is the heating of the motor coil. The better the motor, the smaller the value at no load, and the potential energy refers to the energy to overcome friction, the inertia of the rotor itself, and the potential energy of the rotor itself. In general, when the speed is constant, the inertia energy of the rotor is almost not increased, and this potential energy mainlyVentilation fan motor suppliers https://www.chinakxdq.com/product/ventilation-fan-motor/ overcomes the problem of friction and eventually dissipates in the form of thermal energy, so the smaller the no-load current, the better the performance of the natural motor, especially The lower the no-load current of the motor on the gearbox, the better the gearbox is made. Of course, the larger the gearbox ratio, the greater the resistance in the same design mode. 7. Starting current. Starting current. This parameter is also important. The problem of inertia of the rotor mentioned above is more manifested here. A good motor has a smaller starting current under the same acceleration, and a poor motor is not mentioned. As a car drive, it starts like a cow when it starts, and it does not have the rushing feel of a racing car. 8, Terminal resistance, motor resistance. Hehe, I can’t translate this well. It is given in the Chinese manual of MAXON. The term TERMINAL means terminal, and it can also be regarded as the resistance between the two output terminals of the motor. Actually the same. However, you must not think that this value is the idling current after dividing the rated voltage. Because the motor still has electromotive force in it. There is also heat energy consumption. 9 Max permissible speed. This parameter generally has no effect. Because the speed is controlled by voltage, this situation usually occurs in two cases. One is that you are not honest, you have to apply too high a voltage. The second is very unfortunate. The external energy drives the motor, and it also produces such a speed. The general consequence of exceeding this speed is mechanical damage. But this rarely happens. General motors do not have this parameter. 10. Max continuous current. Maximum continuous current. This current mainly refers to the current that occurs when there is a reverse external force, such as when there is a load. This is also a parameter to consider. Generally, the product of this current and voltage is less than the rated power. This does not mean that the motor has a loss ratio, but it works under high current for a long time, such as at the rated power, which will cause the temperature to rise. The direct consequence is increased resistance. Reduced efficiency and reduced overall performance, with the potential to damage equipment. Working at this value generally guarantees long-term normal operation. 11. Max continuous torque. Maximum continuous torque. It has almost the same effect as the maximum continuous current. I won’t say any more. This value has a more direct relationship with the maximum continuous current, but it is not completely equal. After all, there is heat dissipation. 12.
Max power output at norminal voltage. Maximum output power at rated voltage. In fact, there is a difference between this power and the rated power. This power often does not consider safety, and it is definitely not a value that can be maintained for a long time. It is also often a measured value at 25 degrees room temperature. But this power is often larger than the rated power. According to the information I see, such as the MAXON model, the rated power is 150W, and this value is 491W in one. 13. Max efficiency. Maximum efficiency. It is usually measured at room temperature. Voltage multiplied by current, multiplied by the output power. However, if the motor is running for a long time, this efficiency will be lowered, of course not a lot, unless your motor can already roast potato. This parameter is generally used to calculate the corresponding relationship between several values, such as the relationship of voltage, current and speed torque. 14. Torque constant. Torque constant. This does not mean static torque. The unit is N.M / A and so on.
That is, the torque value per A, or milliamps, this is also an auxiliary parameter, not much use, but to choose a good motor, this value is also a parameter that can be considered. In fact, in actual measurement, this value is not a constant. 15. Speed constant. Speed constant, that is, RPM / V, how much the rotation speed increases for each 1V increase. In fact, as above, the range of its constant value is also limited. Don’t expect 100 times the speed when you add 100 times the voltage. Generally, the higher the voltage is, the lower this value is. 16. Mechanical time constant. Mechanical time constant. 17, rotor inertia rotor inertia. As mentioned before, accelerate and decelerate. If the load is no-load, the smaller the value, the better. But if your load inertia is large and the value is already relatively large, burn the money to reduce this value It doesn’t make much sense. 18. Terminal inductance Motor inductance. 19 thermal resistance housing -ambient Thermal resistance from the motor housing to the environment. This value is actually quite impressive. But generally there are no motors. Because this value is the heat generation under unit power wattage without heat dissipation, naturally, the smaller the better. 20, thermal resistance rotor-housing Thermal resistance from rotor to casing. Basically the same as above. Small is better than big. 21, thermal time constant winding The thermal time constant of the winding is the time that the winding temperature changes. Is how many degrees per second.
No-load speed, or no-load speed. The unit is RPM. revolutions per minute R here is not the meaning of RATE speed, but the meaning of REVOLUTION rotation. That is how many revolutions per minute. The no-load speed has no reverse torque, so the output power and stalled condition are different. This parameter only provides a function of the maximum speed of the motor at the specified voltage. Generally, 6000 revolutions, ah, 12000 revolutions are given outside, which refers to this parameter. 4. Stall torque Stall torque. This is an important parameter for many motors with a load. That is, the moment when the motor is stopped by a reverse external force. If the motor stall occurs frequently, it will damage the motor or burn the driver chip. So when you choose the motor, this is the first parameter to consider in addition to the speed. 5, Speed / torque gradient. If the speed is the Y axis and the torque is the X axis, in general, the motor first has a line parallel to the X axis, and then it drops a bit like the negative exponential form of E. That is, the product of speed and torque decreases with increasing torque. Motor manufacturers recommend that the motor be operated within that line parallel to the X axis. In this range, the current of the motor will not cause the motor to overheat and burn. 6. No load current. No-load current. Or idling current. As mentioned earlier, current and torque are closely related. No-load current must exist, and the energy formed by the product of voltage and voltage is mainly divided into potential energy and heat energy consumption.
Thermal energy is the heating of the motor coil. The better the motor, the smaller the value at no load, and the potential energy refers to the energy to overcome friction, the inertia of the rotor itself, and the potential energy of the rotor itself.

There are many types of stepper motor drivers in the market and their appearances are different
2020年1月20日There are many types of stepper motor drivers in the market and their appearances are different, but in fact, the approximate functions are almost the same, and the distance in price is also relatively large. So more customers focus on quality, so how do we judge the quality of a stepper motor driver? Blower motor suppliers Let’s look at it. How to judge the quality of a stepper motor driver: 1. To have a good quality, the minimum requirement is that its manufacturer has a strong production capacity and qualified quality inspection procedures, so it is necessary to understand the manufacturer, including the company profile , Production environment, staff quality and so on. It is best to conduct on-site inspections and verifications.
If you ca n’t really participate in person, you can still understand the strength of the manufacturer through various channels. 2. ’Surface work’ After doing a good job, stepper motor drivers are particularly important to test samples. Send samples to manufacturers or field distribution points to see if these stepper motor drivers meet their needs.
More hours, The purchase-sales relationship is created at this stage. 3. Manufacturers’ after-sales service problems. Some manufacturers are unable to respond and solve the problem within a few days after the customer responds to the problem due to lack of staff or other reasons. Situation, then we must carefully consider, even some large manufacturing companies, customers are not willing to encounter the discordant side.
