Advantages of stepper motors:
1. Good overload performance. Its speed is not affected by the size of the load. Unlike ordinary motors, when the load increases, the speed will drop. Stepper motors have strict requirements on speed and position.
2. Easy to control. The stepper motor rotates in the unit of "step", and the digital characteristics are more obvious.
3. The structure of the whole machine is simple. The traditional mechanical speed and position control structure is complex and difficult to adjust. After using the stepper motor, the structure of the whole machine becomes simple and compact. The tachometer converts the speed into a voltage and transmits it to the input as a feedback signal. The tachometer motor is an auxiliary motor. The tachometer motor is installed at the end of the ordinary DC motor, and the voltage generated by the tachometer motor is fed back to the DC power supply to achieve the purpose of controlling the speed of the DC motor.
