The V-Angle and Rotor Ducts in Fluence on the Variable Reluctance Permanent Magnet Synchronous Machine on the Output Torque

Abstract

Permanent magnet synchronous motors have risen to be a favour able choice for use in electric vehicles due to their high torque output and efficiency [9], whilst also being relatively lightweight in comparison to their asynchronous counterparts. It is of interest to investigate the parameters of the motor that can be optimized to further improve their efficiency, and in this paper, an analysis of the influence of altering the V angle and rotor ducts on the shaft torque which in turn influences the efficiency will be conducted. Though maximizing efficiency and shaft torque is the major focus of this study, it should be noted that other factors such as weight, cost and thermoregulation impact the choices made to apply the parameters used on the final product, but these findings aim to show how torque and efficiency can be maximized through running such simulations.
