A stepper motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application.
This is a 4 phase stepper motor 57BYGH7630. There are two basic winding arrangements for the electromagnetic coils in the two phase stepper motor: bipolar and unipolar. It is high quality with 13.5 Kg.cm holding torque. The motor length is 78 mm.
