This chapter presents some aspects of electric motors that are specific to traction applications. For electric vehicles (EVs), hybrid EV (HEV), and plug‐in HEV (PHEVs) that require a high‐power motor, induction motors can provide more reliable operation than other types of electric motors. Permanent magnet (PM) motors are the most popular choices for EV and HEV powertrain applications due to their high efficiency, compact size, high torque at low speeds, and ease of control for regenerative braking. Both switched reluctance motors and synchronous reluctance motors have attracted attention in traction applications due to their simple structure, not needing squirrel cage or magnets on the rotor, very little loss on the rotor, and ease of control. Doubly‐salient PM machines are becoming more attractive because of their distinct features, such as high efficiency, high power density, and simple structure. Various analytical and numerical methods have been developed for the thermal analysis of various types of electric motors.
