Motor stator core with skewed slots and production process

The slot lock torqu,e. Hendershot [I], is a 2.25 slot/pole ratio with a 15" pole angle for a 16-pole skewed rotor. The stator has 36 slots.A coefficient of viscous friction is added to the model so that the rotor speed decreases from its initial speed.Cogging torque is undesirable because it introduces vibration and noise, and also makes precise positioning of the rotor impossible because the rotor tends to lock onto a position where it is aligned with the stator poles.
