Modeling and analysis of dual stator windings permanent magnet synchronous motor

The dynamic analysis of dual stator windings permanent magnet synchronous motor (DSWPMSM) with capacitor current injection into the auxiliary winding is presented in this paper. A mathematical model of the machine is proposed in order to study the performance of the motor with phase variable equations which were transformed to d-and q-axis rotor reference frame. Saturation effect is accounted for in the developed model. The model was simulated using MATLAB/Simulink. The electromagnetic torque of the model machine is enhanced which is compared with the conventional line-start interior permanent magnet synchronous motor (LSIPMSM) of the same size.
