Simulation of the 6-phase Fractional Pitch Induction Motors to Reduce Harmonic by using the 3-D Finite Element Method

This paper presents harmonic reductions of 6phase induction motors related to increased torque and filtered a sine waveform of magnetic flux density by adjusting coil pitch with the original structure. Full pitch and fractional pitch systems were considered in terms of simulation results and characteristics for optimized applications. There were 2 tools in MATLAB used for these solutions, a 3-D finite element method to do simulations of this system and a Fast Fourier Transform to calculate the harmonic distortion, respectively. The equation used in the simulations is a second order partial differential equation with time-dependent conditions. The results of both full pitch and fractional pitch systems based on steady state and full load of a 6-phase induction motor, 2-pole, 3-HP, squirrel-cage and double-layer motor were obtained. MATLAB was used for 3-D graphics of the simulated 6phase induction motor.
