1.Brief Introduction of PMG stepper motor
The PM stepper motor with gearbox (PMG) is a combination of the stepper motor and various gearboxes. It can realize low speed and large output torque.
Working Principle
This product is an open-loop control system that converts pulse signal into angular or linear displacement. The amount of displacement can be controlled by adjusting the number of pulses, so accurate positioning can be achieved.
Features
High torque, fast dynamic response, low noise, low cost
Drive Mode
Unipolar or bipolar, constant voltage drive
