Have you known about stepping motors? What are the advantages? How to measure and verify the speed method? Now will give you a brief explanation, and I hope it will help you!
The principle of stepping motor is to convert the pulse signal into angular displacement or linear displacement. Its main advantages are as follows:
1. Good overload performance. Its speed will not be disturbed by the load size. Different from ordinary motors, when the load increases, the speed will decrease. Stepping motor has strict specifications for speed and position.
2. Easy to control. The stepping motor rotates in the unit of "step size", and the digital function is more obvious.
3. Simple structure of the whole machine. The traditional mechanical speed and position control structure is more complex and difficult to adjust. After using the stepping motor, the structure of the whole machine becomes simple and compact.
The speed measurement is that the motor converts the speed into voltage and transmits it to the input terminal as a feedback signal. The tachometer motor is an auxiliary motor, which is installed at the end of the ordinary DC motor. The generated voltage is fed back to the DC power supply to control the speed of the DC motor.
