In most cases, planetary reducers are used in conjunction with servo motors. Mainly because the speed and torque output of servo motors are usually constant. The output speed and torque of the planetary gearbox can be adjusted as needed. The scheme of installing planetary reducers on stepper motors has also been quietly applied in the industry. The characteristic of stepper motors is that the speed can be set according to the required requirements and precise positioning can be achieved.

The function of deceleration stepper motor
Increase the output torque of the motor
Stepper motors have smaller installation dimensions and are often suitable for systems with limited installation conditions. Due to the small size of the stepper motor, the torque is also small. After installing a planetary reducer, it can increase the torque without changing the installation flange.
Realize ultra-low speed operation of the motor
Stepper motors are required to operate at ultra-low speeds, which our stepper motors often cannot achieve. For example, installing a planetary gearbox can achieve ultra-low speed operation at 1 rpm. In some ultra-low speed ranges that stepper motors can achieve, although the resonance zone has been avoided, there may be motor crawling and uneven operation. After installing a planetary reducer, the motor speed has been increased, allowing for ultra low speed operation and smoother motor operation.
Introduction to stepper motor
Achieve higher positioning accuracy
Return gap
Level 1<1 ° Level 2<2 ° Level 3<3 °. Every planetary reduction stepper motor undergoes a return clearance test before leaving the factory. We use laser measurement method to conduct a full inspection of the reducer to ensure that the return clearance of the planetary reduction stepper motor is within the range we promise.
Nickel plating process
The new reducer adopts an all steel outer gear ring, and the inner and outer teeth of the gear ring are nickel plated to improve the hardness of the tooth surface, ensure the rust prevention of the shell, and extend the service life of the reducer. Ensuring the stability and long-term operation of the equipment.
