Chapter 6: Electric Motors and Drives for Electric Vehicle Applications
Abstract ,: Electric vehicle (EV) motors convert battery power to motion, with Permanent Magnet Synchronous Motors (PMSMs) and Induction Motors (IMs) being dominant, while BLDC motors suit lighter vehicles; EV drives (inverters/controllers) manage this power for high torque at low speeds, efficiency, and wide speed ranges , crucial for performance, often using AC power from DC batteries via inverters for smoother, powerful, and efficient propulsion than traditional engines. Types of EV Motors Permanent Magnet Synchronous Motors (PMSM): Highly efficient, high torque from start, used in most passenger EVs (Tesla, BMW i3, Hyundai Ioniq 5). Induction Motors (AC IM): Robust, cost-effective, good for mass production; uses induced current in rotor (e.g., early Teslas). Brushless DC (BLDC) Motors : High efficiency, low maintenance; common in scooters, e-bikes, and smaller EVs. DC Series Motors : Sim...
