What kind of reducer can be used with a stepper motor?

1. Reasons for using a reducer with a stepper motor

The stepper motor switches the frequency of the stator phase current, such as changing the input pulse of the stepper motor drive circuit to make it move at a low speed. When a low-speed stepper motor is waiting for a stepping instruction, the rotor is in a stopped state. When stepping at a low speed, the speed fluctuation will be large. At this time, if it is changed to high-speed operation, the speed fluctuation problem can be solved, but the torque will be insufficient. That is, the torque will fluctuate at low speed, and the torque will be insufficient at high speed, so a reducer is needed.

 

2. What are the reducers commonly used with stepper motors?

The reducer is an independent component consisting of a gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine, and plays a role in matching the speed and transmitting torque between the prime mover and the working machine or the actuator. There are many types of reducers. According to the transmission type, they can be divided into gear reducers, worm reducers, and planetary gear reducers; according to the number of transmission stages, they can be divided into single-stage and multi-stage reducers; according to the shape of the gear, they can be divided into cylindrical gear reducers, bevel gear reducers, and bevel-cylindrical gear reducers; according to the layout of the transmission, they can be divided into expanded reducers, split-flow reducers, and coaxial reducers. The reducers installed in stepper motors include planetary reducers, worm gear reducers, parallel gear reducers, and screw gear reducers.
