The invention discloses a control method applicable to a doubly salient electro-magnetic motor. According to the method, a three-phase twelve-beat control strategy is provided for switching-on and switching-off of a power converter main switch tube based on inductance characteristics of the doubly salient electro-magnetic motor in operation. In the premise of ensuring reliable operation of the motor, in order to inhibit torque pulsation and improve output torque, an electrical cycle is divided into twelve stages, each stage is corresponding to a switching-on mode of the switch tube for controlling a current in the corresponding direction to flow into the corresponding phase, so that the motor forms twelve working conditions in the electrical cycle. According to the motor provided by the invention, the torque pulsation caused by the condition of adding a dead time (namely the time when an upper switch tube and a lower switch tube are simultaneously switched off) into a commutation time is avoided, an effective section of the inductance can be fully utilized to introduce the current in the corresponding direction, and thus the output torque is improved to a certain extent.
