Abstract
AbstractThis paper gives a concise review on mathematical modeling of brushless direct current (BLDC) motor, the challenges on BLDC motor, torque ripple reduction techniques, condition for minimum commutation torque ripple, and different control strategies for torque ripple reduction in sensor and sensorless BLDC motor. This review also discusses the comparison between sensor and sensorless BLDC drives, merits of sensorless BLDC drive, and outcomes of different torque ripple reduction techniques. It also gives an idea to select better control strategy for specific BLDC drive applications. The best-suited control strategies have the advantages such as high efficiency, minimum torque ripple over the entire speed range, less switching loss, simple modulation scheme, improvement in DC voltage utilization, smooth and noiseless operation, and regulation in the speed of BLDC motor. The MATLAB simulation tool is used to verify the results of few topologies.KeywordsSensor BLDCSensorless BLDCTorque rippleCuk converterLine–line flux linkage
