Abstract: The present disclosure provides a rotor mechanism includes a rotor core and a plurality of rotor bars. The rotor core has a plurality of insertion slots arranged along an edge of the rotor core. Each of the plurality of rotor bars has an insertion portion and two protruding portions. The insertion portions are respectively located in the plurality of insertion slots, wherein in each of the plurality of rotor bars, the two protruding portions are respectively connected to two opposite ends of the insertion portion and respectively protrude from two opposite sides of the rotor core, and the two protruding portions each has an extension direction, that has an angle with respect to an extension direction of the insertion portion, in order to clamp and fix the rotor core therebetween. In addition, the present disclosure also provides a method for manufacturing the rotor mechanism.

Abstract: A motor driving method is applied to a motor with a rotor comprising a magnetic reluctance structure. The motor driving method comprises enabling the motor by an asynchronous driving method, controlling the motor by the asynchronous driving method according to a speed regulation command, detecting a rotor speed of the motor and determining whether the rotor speed is larger than a speed threshold, and when the rotor speed is larger than the speed threshold, controlling the motor by a synchronous driving method.
