A Review on Torque and Current Ripple Minimization Techniques in a BLDC Motor Drive for EV Applications

The approaches for reducing torque-based ripple in brushless DC motors are investigated in this research (BLDC). It is caused by a range of variables, including the motor’s natural design process and its inverter drive commutation features. This torque ripple can cause low-quality speed-torque characteristics, noise, vibrations, and serious failures in sensorless motor drives. In the literature, various solutions for decreasing torque ripples have been published. This study provides a thorough examination of various methodologies as well as a summary of the findings from the literature. The primary goal of this study is to present a practical method for improving the performance of a BLDC motor and its drive for the rapidly developing electric car market.
