A pole pitch in electrical machine _____________(a) = 180° electrical

1.	A pole pitch in electrical machine _____________(a) = 180° electrical(b) = 180° mechanical(c) > 180° electrical(d) < 180° electricalThis question was posed to me in final exam.This intriguing question comes from Terms Pertaining To Rotating Machines in section Basic Concepts in Rotating Machines of Electrical Machines
Answer» The correct OPTION is (a) = 180° electrical For EXPLANATION I would SAY: Pole PITCH is ALWAYS expressed in electrical degrees, rather than in mechanical degrees. pole pitch = 180 electrical degrees or π electrical radians.
