Abstract
A new Dual Stator Multiphase Phase Induction Motor (DSMIM) configuration is proposed and described in this paper. Steady state equivalent circuit of DSMIM is developed and its performance parameters are calculated. The efficiency curves plotted under different excitation modes of the machine assists in operating it at a better efficiency for wider load range. Thus, the proposed configuration can be utilized in Electric Vehicles (EV) to efficiently support a sudden load change during acceleration, cruising and uphill driving patterns. A Finite Element Method (FEM) based design of the machine is done using MAGNET software. The electromagnetic performance of DSMIM is analyzed through the flux patterns obtained at different excitation modes. Its electromechanical performance is studied by analyzing the current, torque and speed developed under load driven conditions. The article also proposes an ideology behind the mechanical arrangement of DSMIM for fabrication. The simulation results are included to illustrate the performance of DSMIM. The results are compared and validated with the analytical results obtained through equivalent circuit approach.
