Design of switched reluctance motor competitive to 60 kW IPMSM in third generation hybrid electric vehicle

In this paper, a design of a switched reluctance motor (SRM) having competitive torque, power, speed range and efficiency of the interior permanent magnet synchronous motor (IPMSM) employed in the 2009 Toyota Prius has been investigated. The maximum torque of 207 Nm is needed up to the knee speed of 2768 r/min. The output power of 60 kW is required in the speed range from 2768 r/min to 13900 r/min. It is shown that the above requirements can be satisfied with a designed SRM, although, the current density and the weight are slightly increased. At the high speed, simulation results show that the output of the designed SRM is found to be greatly enhanced with respect to that in the IPMSM.
