In a synchronous machine, if pitch of the coil = [(r - 1) /r]th fraction of full pitch, then:

(r + 2)th harmonic can be eliminated from the induced emf in a phase

(r - 1)th harmonic can be eliminated from the induced emf in a phase

(r + 1)th harmonic can be eliminated from the induced emf in a phase

rth harmonic can be eliminated from the induced emf in a phase
