What are the main differences between a stepper motor and an ordinary motor?
Stepper motors are used for precise control or position determination; ordinary motors are used for speed regulation; of course, motors are used here.
Stepper motor is relatively better to control the motor rotation of an angle, and the ordinary motor is often only speed regulation, but it can not like stepper motor, according to your request and walk a relative distance.
The difference between the stepper motor and general motors is mainly the driving pulse form (the control system sends out a pulse, you can make the motor rotate an angle), because of the characteristics of stepping motor and modern digital control technology combining (especially suitable for mechanical and electrical integration products). However, stepper motor in the control accuracy, speed range, low speed performance is not as good as the traditional closed-loop control of DC servo motor. The stepping motor can be used in the situation where the accuracy is not high, and the stepping motor can display the characteristics of simple structure, high reliability and low cost. When used properly, it can even compare favorably with the performance of DC servo motors.
