Recent Trends and Challenges of Electric Motor Technologies

Abstract

The growing popularity of electric vehicles (EVs) is being interpreted as a natural progression towards better technology in the automotive industry. This necessitates a thorough examination of the engine, which is the beating heart of these EVs. An electric vehicle's motor is a critical part of the vehicle's propulsion system, with the capacity to affect the vehicle's efficiency, weight, cost, dependability, power output, and performance. As a result, there is a pressing need for comprehensive comparison research that evaluates and contrasts the many motor types and topologies now in use. The capabilities of DC motors, induction motors, switching reluctance motors, permanent magnet AC motors, and permanent magnet DC motors, all of which can be employed for electric vehicle propulsion, are discussed. Recommendations for various novel designs of brushless DC motors are offered, along with a comprehensive assessment of current motors and the potential use of power electronic approaches to EVs. Motors with permanent magnets can be either a permanent magnet hybrid or a permanent magnet spoke or insert
