Abstract

A technique of switched stator is employed in a radial Flux BLDC motor to improve the energy efficiency of an electric vehicle. Electric vehicle (EV) certainly, shall be a replacement to the gasoline engine vehicles in near future considering environment protection inadequacy of fuels. This concept is arrived for in wheel direct drive for a two wheeler which doesn't have any transmission mechanism. The battery-drive system should be highly efficient to make the EV to overcome its speed, load and mileage limitations. The technique of switched stator BLDC motor is arrived to improve the efficiency of battery by switching the outer and inner stator of BLDC motor which are designed with different torque/back-emf constants. This paper presents the configuration of vehicle drive train, architecture of Switched stator-BLDC (SS-BLDC) motor and its control strategy to achieve the required objectives. Simulation model of the total electric propulsion is built and analysis carried out by taking a standard driving schedule. Important performance indices of vehicle are derived and the results are very encouraging. The obtained results have shown an increase of 38% in mileage of vehicle for given driving schedule with proposed technique.
