Paper Title : Average torque improvement of BLDC motor in battery electric vehicle
Author Name : Rupam , Sanjay Marwaha and Anupma Marwaha
Abstract :

Amongst automobiles, the domain of electric vehicles is being targeted globally by researchers from its inception. Hence, a great proliferation in the advancement of electric vehicles has been documented in recent years. The cogging torque of the motor is the main cause of acoustic noise and vibration produced in the electric vehicle. The objective of this paper is to minimize the cogging torque and improve the average torque of the brushless direct current (BLDC) motor used in battery electric vehicles. The power rating of the selected reference vehicle is computed using kinematic equations. The selection of material and pole slot combination has a great impact on motor torque which influences the overall performance of the vehicle. An optimal design of a BLDC motor is presented by selecting distinct values of rotor pole embrace factor by using a parametric approach of ANSYS Maxwell software. With the help of the finite element method (FEM), the magnetic analysis of the proposed motor has been carried out. Consequently, it is observed that the designed model offers significant reduction in cogging torque with improved average torque of the motor. Accordingly, the rating of the battery to power the motor for propulsion has been computed.

Keywords : Battery electric vehicle, BLDC motor, Finite element analysis, Permanent magnet.
