Design and Analysis of Rotor Technology for Electric Vehicle Application

Present electric vehicles have regained attention in the automobile sector. The central part of the electric vehicle is the motor. Most EVs use Induction motors, permanent magnet motors, and in some experiments switched reluctance motors, consisting of a single rotor with single winding technology. However, they are not gained high torque. A comprehensive approach should be taken towards the design of an electric motor for an electric vehicle, along with the choice of suitable rotor topology and slot combination. In this paper a novel design of the single rotor, dual winding technology is proposed. The proposed model consists of a motor winding, and generator winding on the same rotor, which works as both motor as well as generator. The design of novel rotor winding guarantees the generation of high torque and power density for crucial applications of electrical vehicles. The design of a single rotor with twin windings for eventual use in electric vehicles can reduce the burden on EV charging stations. This rotor technology has advantages like high torque, low weight and availability with low cost. This paper’s primary objective is to research various slot winding topologies for electric motors, as well as to build a prototype and validate the design.
