Abstract: This paper compares a permanent magnet motor to an induction motor in a hybrid electric vehicle application. The comparison considers replacing an existing 50kW Interior Permanent Magnet (IPM) motor with a copper-rotor induction motor (CR-IM). The 2004 Toyota Prius Hybrid system is used as the baseline for the analysis. The size, weight and cost of the two topologies are compared and the difference in lifetime energy use over various drive cycles is analysed. Additional considerations including the impact on battery sizing and the inverter VA rating are also considered and discussed.
