The invention discloses a control method for reducing the pulsating current of a five-phase brushless direct current motor. In the method, a new running state is interposed behind each of the original running states of the five-phase brushless direct current motor, wherein in the new running state, one of four switch-on bridge arm switches in a certain original running state is switched off and the other three bridge arm switches are still switched on. The conduction time of each phase of winding is varied, namely, a control method for advanced switch-off time t is varied, so that ten new interposed running states and ten original running states run in turn, the pulsating current of a winding of the five-phase brushless direct current motor can be lowered greatly, the running noise of themotor is lowered and the no-load noise of the motor is lowered particularly remarkably; simultaneously, torque pulsation is reduced and the running efficiency of a system is improved.
