along withservo motorThe development of technology and the demand for high torque density and high power density in high-precision applications have led to servo motor speeds exceeding 3000rpm, resulting in a significant increase in servo motor power density. This means that servo motors need to be used in conjunction with reducers, and the determining factors are mainly examined from the perspective of application requirements and cost considerations. However, in what kind of application scenarios must servo planetary reducers be used?

1. Heavy load and 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, military technology, robots, etc. Their common feature is that the torque required for load movement often exceeds the torque capacity of the servo motor itself. By using a reducer to increase the output torque of the servo motor, this problem can be effectively solved.

2. Boosting torque: The way to increase output torque may be to directly increase the output torque of the servo motor, but this method does not require the use of expensive and high-power servo motors. The motor also needs a stronger structure, and the increase in torque is proportional to the increase in control current. When using larger drivers, the increase in power electronic components and related electromechanical equipment specifications will significantly increase the cost of the control system.

3. Increase efficiency: In theory, increasing the power of the servo motor is also a way to increase output torque. The power density of the servo system can be doubled by increasing the speed of the servo motor by twice, without the need to increase the specifications of control system components such as servo drivers, which means there is no need to increase additional costs. And this requires the combination of planetary reducers to achieve the goal of increasing torque. So, the development of high-power servo motors requires the use of reducers instead of omitting them.

4. Improving performance: Improper matching of load inertia is one of the biggest reasons for unstable servo control. For large load inertia, the inverse square of the reduction ratio can be used to allocate 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. Due to the decrease in speed, the controllability of servo motors may experience some degree of attenuation, especially in signal interception at low speeds and stability of current control, which is particularly evident. Therefore, using a reducer can enable the motor to have a higher speed.

6. Reducing equipment costs: From a cost perspective, assuming that a 0.4KW servo motor paired with a driver requires one unit of equipment cost, a 5KW servo motor paired with a driver requires 15 units of cost. However, if a 0.4KW servo motor paired with a driver and a set of reducers are used, the aforementioned 15 unit cost can be achieved, saving more than 50% in operating costs.

Therefore, users decide to choose planetary reducer products based on their different processing needs. Generally speaking, there are requirements for low-speed, high torque, and high power density in machine operation, and the vast majority of them use planetary reducers.
