Investigation on airgap selection for switched reluctance motor on low power electric vehicles

The increasing cost of electric vehicles (EVs) mainly depends on rare earth material rotating machines. The polyphase machine has drawbacks of demagnetization, high fault-tolerant and increasing losses. Compare to these machines the low-cost silicon switched reluctance motor (SRM) drive characteristics perfectly suit EV drive. This paper is carried out to design and development of SRM to investigate the airgap size between double salient poles. The proposed rating is 2 kW, 750 rpm and 8/6 topology by selecting stator and rotor optimal geometric parameters to design an efficient EV-SRM configuration. Analysing the different airgap size effects on the Multiphysics parameters of low-speed SRM output power, iron loss, average static torque, and efficiency. JMAG express software simulated the airgap range between 0.2 mm and 1.5 mm, the results are compared and presented. Copyright (C) 2022 Elsevier Ltd. All rights reserved.
