With the development of servo motor technology, the requirements for high torque density and high power density in high-precision applications have caused the speed of the servo motor to exceed 3000 rpm, which in turn has greatly increased the power density of the servo motor. This means that the servo motor needs to be used with a reducer, and the determining factors are mainly based on application requirements and cost considerations. However, in what application scenarios must a servo planetary reducer be used?
1、Heavy-load, high-precision scenarios: This is necessary when the load must be moved and precise positioning is required. Generally, automation equipment such as aviation, satellites, medical care, military technology, and robots are used. Their common feature is that the torque required to move the load often far exceeds the torque capacity of the servo motor itself. This problem can be effectively solved by using a reducer to increase the output torque of the servo motor.
2、Increase torque: The method of increasing output torque may be to directly increase the output torque of the servo motor, but this method does not necessarily require the use of expensive and high-power servo motors. The motor must have a stronger structure, and the increase in torque is proportional to As the control current increases, a larger driver is used, and the specifications of power electronic components and related electromechanical equipment increase, which will greatly increase the cost of the control system.
3、Increase usage efficiency: In theory, increasing the power of the servo motor is also a way to increase the output torque. The power density of the servo system can be doubled by increasing the speed of the servo motor twice, and there is no need to add control systems such as servo drives. The specification of the components means that no additional cost is required. This requires the combination of a planetary reducer to achieve the purpose of increasing torque. Therefore, the development of high-power servo motors must be coupled with the use of reducers, rather than omitting them.
4、Improve performance: Improper matching of load inertia is one of the biggest reasons for unstable servo control. For large load inertia, the inverse square ratio of the reduction ratio can be used to adjust the optimal equivalent load inertia to obtain the best control response. So from this perspective, planetary reducers are the best match for the control response of servo applications.
5、Increase the service life of the equipment: The planetary reducer can also effectively solve the attenuation of the low-speed control characteristics of the motor. Since the controllability of the servo motor will be attenuated to a certain extent due to the reduction in speed, it is especially easy to see the stability of signal interception and current control at low speeds. Therefore, using a reducer can make the motor have a higher speed.
6、Reduce equipment costs: From a cost perspective, assuming that a 0.4KW servo motor is paired with a driver, it will cost one unit of equipment cost, and a 5KW servo motor paired with a driver will cost 15 units. However, if a 0.4KW servo motor is used with a driver, it will cost 15 units. A set of reducers can achieve the aforementioned tasks that cost 15 units, saving more than 50% in operating costs.
Therefore, users decide on the planetary reducer product they choose based on their different processing needs. Generally speaking, when machine operation requires low speed, high torque, and high power density, most of them use planetary reducers.
