Stepper motor is an electromechanical device which is used to convert electrical energy into mechanical energy. These motors are brushless DC synchronous motors which move in discrete mechanical steps. They have several coils that are grouped into classes know as phases. Stepper motors can move one step ahead at a time by energising each phase in sequence.
What are the pros and cons of stepper motor?
Stepper motors have several various size, types and electrical characteristics. However, these motors have many advantages and disadvantages, which are:
