Dynamic Design and Simulation Analysis of Permanent Magnet Motor in Different Scenario of fed Alimentation

This paper deals with investigation on non purely sinusoidal input supply analysis of line-start PMM using finite element analysis (FEA), in the present times a greater awareness is generated by the problems of harmonic voltages and currents produced by non-linear loads like the power electronic converters. These combine with non-linear nature of PMM core and produce severe distortions in voltages and currents and increase the power loss, additional copper losses due to harmonic currents, increased core losses, electromagnetic interference with communication circuits, efficiency reduction, increased in motors temperature and torque oscillations. In addition to the operation of PMM on the sinusoidal supplies, the harmonic behavior becomes important as the size and rating of the PMM increases. Thus the study of harmonics is of great practical significance in the operation of PMM
