Stepping motors are often used together with reducers. This combination is usually called a stepping geared motor. Why does a stepping motor use a reducer? What reducer is used for the stepper motor? The characteristics of these two aspects and the types of stepper motor reducers are introduced in detail below.

Why stepper motors use reducers:

1. 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. At this time, if the speed is changed to high speed, 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.

2. The step angle of small (below 50mm) PM-type stepping motors is 7.5°, and this kind of motors will have the problem of position control accuracy changes.

3. The output shaft of the stepper motor adopts the direct drive load mode. When the load inertia is large, the acceleration torque will be insufficient.

4. It is desired to brake at low speed and high torque.

What reducer to use for stepper motors:

1. Worm gear reducer for stepping motor: Worm gear reducer is characterized by relatively large volume and not compact structure. It can be self-locking under certain conditions, and its efficiency is relatively low, about 60%. Because the efficiency is relatively low, it cannot be satisfied in many occasions, and it is generally not recommended to be used with stepping motors.

2. Planetary reducer for stepping motor: The planetary reducer planet, as the name implies, revolves around the sun, so the planetary reducer is like this. There are three planetary gears revolving around a sun gear. The planetary reducer has the characteristics of high strength, small size, low noise, low price, large transmission torque, long life, etc., and the transmission is good, about 80% or more;

3. Standard stepping motor gearbox reducer: the diameter specification of the miniature standard stepping motor gearbox reducer is between 3.4mm-38mm, reduction ratio, no-load output speed, load output speed, driving noise, return clearance and other technologies Parameters can be customized as required.

4. Non-standard customized step reducer: non-standard step motor reducer products customized according to actual application requirements, widely used in smart home, intelligent robot, communication equipment, 3C electronics, linear drive, medical equipment, industrial equipment, virtual in real industry.
