Abstract

The brushless DC (BLDC) motor is recognized by the linear speed to voltage and torque to current. It has high fast dynamic response and high power density with high proportion of torque in sprite of small size drive. However, it is difficult to conventional BLDC motor to drive at high speed operating mode (limited top speed). It is because of the torque and speed response characteristic of the motor at high speed operating mode are deteriorated by the motor inductance components in stator winding. Phase advance angle method is one method used to control the phase current and improve torque and speed response at high speed operating mode of BLDC motor. This project concentrates on the operation of BLDC motor under high-speed motoring mode. Extended simulation results prove the validity of phase advance angle control method, considering lossless motor operation and the same parameters of an actual BLDC motor. In this project also, the results of laboratory testing are demonstrated to prove the compatibility of the purposed phase advance motor drive on actual BLDC motor. Both simulation and experimentation results confirm that phase advance angle control method is capable to extend the speed beyond the designed motor speed.
