Comparison, Induction Vs. PM Motors for EVs
Electric vehicles (EVs) rely on two main types of motors for propulsion: AC induction motors and permanent magnet (PM) synchronous motors. Each technology has distinct operating principles and performance characteristics that influence vehicle efficiency, torque output, cost, and design decisions. Below we explore how each motor works, compare their performance metrics (efficiency, torque density, cost, maintenance, scalability), and provide guidance on choosing the right motor for an EV application.
