Study on DC-DC Converter fed Sensor-less Motor Drive

Abstract

Brushless DC motor widely used in different sectors for high efficiency and very low maintenance. The report concerns about the performances of Brushless DC (BLDC) motor with KY and four quadrant converters. Input voltage has been varied for both of them and instantaneously the output voltage is recorded along with the theoretical value. The simulation of the converter circuits have been made using MATLAB/Simulink platform. The parameters of the BLDC motor under argument are stator back electromotive force (emf), electromagnetic torque and motor speed. An attentive determination has been made to represent the motor parameters in a simply comparable manner for both the converters. Lastly, a conclusion has been drawn on the best outcome of the converter among the two to enable the motor to function efficiently and help us get desirable results when the motor is in operation
