find answer in my question?
Ques:how you generate sinusoidal emf in a synchronous M/C?
Ans:it is from the rotating poles or say rotating mmf which is sinusoidal due to the constant air gap b/w stator and rotor poles. so can you change this air gap periodically, the answer from my side is not possible. Hence one may produce only sinusoidal emf
