Answer 2

The correct answer is option (C.) 0.79.

Explanation:

• For 125kW 3 phase induction motor if bore diameter is 1 m ,then pole pitch is 0.79 m.
• Pole Pitch is equal to the total number of armature slots divided by the total number of poles in the machine.
• For example, if there are 96 slots on the armature periphery and 4 poles, the number of armature slots that come between two adjacent pole centers would be 96/4 = 24.
