In this work, harmonic analysis of current and voltage waveforms, and investigation of efficiency, output power and torque characteristics of a three-phase, squirrel cage induction motor with full-, under-, and over-pitched stator windings under sinusoidal excitation are carried out. Performance analysis have been performed via Ansys/RMxprt software by modelling the stator winding with coil pitches of 100°, 120°, 140°, 160°, 180°, 200°, 220°, 240° and 260°. Current and voltage harmonics analysis have been performed in Matlab using the data obtained from Maxwell/2D simulations. Results showed that both under-pitched and over-pitched coils can be used to eliminate harmonics in the current and voltage waveforms. Under-pitched coils provide higher efficiency than the over-pitched coils. There is no unique coil pitch configuration to eliminate all harmonic components. Therefore, in order to eliminate a specific harmonic component, a specific coil-pitch must be applied.
