Design and Dynamic Simulation of Five Phase Interior Permanent Magnet Machine for Series Hybrid Electric Vehicles

Dynamic behavior analysis of electric motors are required in order to accurately evaluate the performance, energy consumption and pollution level of hybrid electric vehicles. Due to high torque to inertia ratio, high reliability, high efficiency and power density, five phase interior permanent magnet machines (IPMs) are good candidate for hybrid electric vehicles. In this paper dynamic performance of a five phase IPM machine for series hybrid electric vehicles application is discussed. For this purpose a high torque density five phase IPM machine with low torque pulsation is designed. The mathematical model of the proposed IPM motor is given. A vector control strategy based on the space vector pulse width modulation (SVPWM) technique is provided to control the machine over a wide speed range. Finally the system is simulated for different operating modes of a typical drive cycle. Extensive simulation results show the accurate performance of the proposed machine.
