A stepper motor converts a pulse signal into an angular displacement or a linear displacement.

First, the overload is good. The speed is not affected by the size of the load. Unlike ordinary motors, when the load is increased, the speed will drop. The stepper motor has strict requirements on speed and position.

The second is convenient control. The stepper motor rotates in units of “steps” and the digital features are more obvious.

Third, the structure of the whole machine is simple. The traditional mechanical speed and position control structure is complicated and difficult to adjust. After using the stepping motor, the structure of the whole machine is simple and compact. The tachometer motor converts the speed into a voltage and transmits it to the input as a feedback signal. The speed measuring motor is an auxiliary type motor. A speed measuring motor is installed at the tail end of the ordinary DC motor, and the voltage generated by the speed measuring motor is fed back to the DC power source to achieve the purpose of controlling the speed of the DC motor.
