Können Schrittmotoren mit Planetengetrieben ausgestattet werden? Worauf muss ich achten?

Stepper motor equipped with a planetary reducer is called stepper planetary reducer, at present, is a more widely used reducer equipment, mainly used in smart cars, 5G communication, smart medical, smart city, smart logistics, smart robot, smart home, consumer digital products, machinery and equipment, automatic industrialization and other fields, stepper motor configuration planetary reducer pay attention to the following points of knowledge.

1. Check the required torque, if it is out of range, then increase the gearbox, the reason for doing so is to increase the torque.

2. Stepper motor is an open-loop control element, which converts electrical pulse signals into angular or linear displacements. In the absence of overload, the motor speed and stop position depend only on the frequency and number of pulses of the pulse signal and are not affected by changes in load. When the stepper driver receives the pulse signal, the set direction rotates at a fixed angle, called the “stepping angle”, and the direction of rotation runs gradually at a fixed angle. By controlling the number of pulses, the angular displacement can be controlled to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.

3. The principle of planetary reducer is a power transmission mechanism which uses a gear reducer to decelerate the motor revolution to the required revolution and obtain a larger torque. The gears with few teeth on the drive shaft of the planetary reducer mesh with the large teeth on the output shaft to achieve the deceleration. A common reducer will also have several pairs of gears meshed in the same principle to achieve the desired reduction. Planetary gearboxes are widely used in servo, stepper, DC and other transmission systems for their small size, high transmission efficiency, wide reduction range and high accuracy.

The above is the stepper motor with planetary gearbox related knowledge, master these basic knowledge and principles, in order to better use the equipment to ensure the normal and stable operation of the equipment!
