A stepper motor or a step motor is a brushless, synchronous motor which divides a full rotation into a number of steps. Unlike a brushless DC motor which rotates continuously when a fixed DC voltage is applied to it, a step motor rotates in discrete step angles.The stepper motor can be controlled with or without feedback.

In a 3-Φ Induction motor, the stator of the motor will generate a rotating magnetic field or RMF because of the phase shift with 120 degrees within the 3- Φ supply input.So the RMF revolves with the stator of its own speed which is known as synchronous speed and it is denoted with 'Ns'. The rotating magnetic field (RMF) converses with the rotor; because the change in flux can …
