摘要： A method for controlling a brushless DC motor, comprising transmitting a phase-inversion signal to a motor control unit by a rotor position detecting unit after a motor enters a stable state, advancing or delaying phase shift by the motor control unit at an offset electrical angle, recording and comparing phase current values In at different offset electrical angles whereby obtaining an optimum offset angle αm corresponding to the minimum phase current value Imin, and advancing or delaying phase shift by the motor at the optimum offset angle αm. As the motor enters a stable state, the motor advances or delays phase shift at the optimum offset angle αm, at this time operating current of a coil winding of the motor is the minimum, which saves power and reduces cost.
