Among various types of motor drives, permanent magnet (PM) brushless motor drives, especially the PM synchronous motor drive, are currently the most attractive motor drives for electric vehicle (EV) propulsion. This chapter presents two major PM brushless motor drives, namely the PM synchronous and PM brushless DC (BLDC) types. It describes their PM materials, system configurations, machine topologies, inverter topologies, and control strategies. The chapter also discusses the corresponding design criteria, design examples, and application examples for EV propulsion. PM materials are the key of PM brushless motor drives that provide the machines with lifelong excitation. The system configuration of PM brushless motor drives for electric propulsion is similar to that of induction motor drives. PM brushless motors have become the preferred choice for EV propulsion because of their high efficiency and high power density.
