Electric Propulsion Motors: A Comparative Review for Electric and Hybrid Electric Vehicles

The problem of global warming and air pollution has attracted the peoples to use the non-fossil fuels. To dealt with it automakers, governments, and customers are attracting more towards the use of electric (EVs) and hybrid electric vehicles (HEVs). This type of vehicles to be widely accepted, a sophisticated system is required to cater to all EV needs. In this paper, comparative analyses of different electric propulsion systems have been presented for electric vehicle applications. For this, DC motors, induction motors, brushless permanent magnet motors have been studied. As per technology aspect, induction motors are better but brushless permanent magnet motors are much better for the electric and hybrid electric vehicle applications. Brushless permanent magnet motors are fuel-efficient and conserve environment through low emissions. Due to low cost of the magnetic materials and high starting torque of brushless permanent magnet motors make them selective for the EVs and HEVs applications.
