Performance Analysis of Brushless DC Motor under Different Loading Conditions

This paper deal with the speed response characteristics analysis of brushless dc motor under different load variations. BLDC drive are widely used motors now a days due to its good speed control characteristics and high efficiency which improves the performance of motor. PI controller is used in motor operation to maintain the constant speed. The analysis is carried out in three different type of load condition which are given as under load, rated load and overload conditions. The performance of BLDC motor is observed through speed, current, back emf and torque response. To evaluate the result appropriate value of Kp and Ki of controller has been taken in order to get the better result for characteristics parameter of the speed response of BLDC motor. The result are then calculated mathematically and analysed according to the load variations. The required model has been developed using Simulink Matlab and speed torque characteristics graph is also analysed using PI controller.
