Question

How fractional pitch winding desreases leakage reactance in induction motor?

Answer 1

leakage reactance becomes high. The number of slots should be selected to give an integral number of slots per pole per phase. The stator slot pitch at the air gap

Answer 2

Explanation:

be shown later, fractional-pitch windings, when used in ac synchronous and .... the armature reactance. 4. ... of coils (slots/pole) increases, the distribution factor kd decreases .
