Abstract

Multi-phase induction motor (MIM) drives with polephase modulation (PPM) is suitable for the Electric vehicle(EV) applications because of the reasons, like constant power operation with high efficiency over an extended speed-torque range and high reliability. By using Pole-Phase modulation, in this paper a 45-phase squirrel-cage induction motor (IM) drive is proposed with 1:3:5:9:15 speed ratios for EV applications. The proposed 45-phase IM drive with 90 stator slots is able to operate at five different pole-phase combinations, i.e., 45-phase 2-pole, 15-phase 6-pole, 9-phase 10-pole, 5-phase 18-pole and 3-phase 30-pole. The above five combinations make this MIM drive is suitable for EV applications, which eliminates the mechanical gear system in conventional EV. This can be helpful for saving the size and weight of the vehicle. This MIM drive offers the high torque for starting acceleration and gradient routes at low speeds and provides the high power for medium and high speed cruising, which is analogous to the typical five gear IC engine. The simulation of the 5hp 45-phase IM drive is verified with the help of Ansys Maxwell-2D (an electro-magnetic design tool) and Simplorer environment by co-simulating the FEM 2-D model.
