What is stepper motor? Classification of stepper motor

Stepper motors are DC motors that have multiple coils arranged in groups called ‘phase’. Each phase gets energized in sequence to rotate the motor one step at a time. We can get a very precise positioning and speed control of the stepper motor through computer controlled stepping. This allows the stepper motor to be used for precision motion control applications.
