1.	For a P-pole machine, the relation between electrical and mechanical degrees is given by _____________(a) θelec = 2/P θmech(b) θelec = 4/P θmech(c) θmech = P/2 θelec(d) θelec = P/2 θmechThe question was posed to me in examination.My query is from Terms Pertaining To Rotating Machines topic in section Basic Concepts in Rotating Machines of Electrical Machines
Answer» The correct answer is (d) θelec = P/2 θmech Explanation: For a P-pole MACHINE, P/2 cycles of EMF will be generated in ONE REVOLUTION, and thus θelec = P/2 θmech.
