In contact with the stepper motor driver and controller, many friends are easy to confuse, do not know how to distinguish between the two, in fact, the two are very good to distinguish, the following Vacuz briefly explain it to you! Hope it can help you!

Stepper motor driver: the main function is to send the pulse signal from the controller, convert it into angular displacement, and then send it to the stepper motor.

Stepper motor controller: is dedicated to sending pulse signals to the driver, PLC, microcontroller, control card, etc. are all controllers.

You can say that the motor is connected to the drive above, the drive is connected to the controller above, the motor, drive, controller all parts complete, in order to constitute a complete motor system. Of course, there are some drives do not need a controller, can be their own analog pulse signal, relatively speaking, the cost is higher, the field of application is also relatively small.

Simply put, one is the control, one is the implementation, the controller is to control the stepper motor in when to turn, how many pulses, the driver is used to drive the motor, the driver can subdivide the motor pulse, increase the output current, and the distribution of pulses.

The above is the difference between stepper motor driver and controller, I believe that after reading the above introduction, many friends have a preliminary understanding of the two, you can go find some relevant books and knowledge points, the system to learn!
