Brushless motors are used in electric vehicles to convert electrical energy into rotational motion. This paper compares different methods of controlling brushless DC motors by using pulse-width modulation-based techniques. These techniques are quite popular in industries for variable drives. In this paper with the help of MATLAB simulations, authors have compared different approaches using pulse-width modulation techniques to control brushless DC motor parameters. On the basis of industrial application, two controlling methods for control of brushless DC motors are majorly used by designers. These pulse-width modulation-based techniques include pulse-width modulation generator with buck converter and pulse-width modulation under commutation logic. Both of these techniques have been implemented with the help of tools in MATLAB. The responses of buck converter and under commutation logic-based approach are compared with different load conditions. These methods are effectively used in the speed control of electrical vehicle drives. Applications of these techniques with their advantages of using in electric vehicle are also discussed.
