How to realize the positive and negative rotation of the stepper motor?

Leave a Comment / Controller, Development tool / By

The stepper motor is a discrete value control motor that converts the electric pulse excitation signal into the corresponding angular displacement or linear displacement. This kind of motor moves one step every time an electric pulse is input, so it is also called a pulse motor. A stepping motor is a micro motor that converts …
