Abstract
Line start permanent magnet synchronous motors (LSPMSMs) are now being widely used in the industry because of their attractive features such as, high efficiency, high power factor as well as high power density. Accurate modeling of LSPMSMs is the first step in recognizing abnormalities in such motors. This paper presents a step towards an accurate mathematical modelling of LSPMS motor under asymmetrical stator windings condition. The developed mathematical model has been implemented using MATLAB/SIMULINK. A 4hp, 4-pole, 380V LSPMS motor is used in the simulation of the developed model to investigate the performance of the motor under different loading levels and stator winding asymmetric conditions. Simulation results show that under asymmetrical stator winding oscillation are clear in the electromagnetic torque. In addition, due to this asymmetry in stator windings, the torque experience high oscillations at steady state when compared to the transient period.
