What is a Brushless DC Motor Construction?

The brushless DC (BLDC) motor is a type of the synchronous electric motor. In other words, the rotating speed of the electric motor's rotor is subject to the impact of the speed of the stator's rotating magnetic field and the number of the stator's poles (p), namely n=60.f/p. When the number of the stator's poles is fixed, change of the
