<P>PROBLEM TO BE SOLVED: To provide a motor controller having operability similar to a gear change of an automobile of an internal-combustion engine. <P>SOLUTION: An actuator control circuit 27 to drive and control an actuator, a core position selecting circuit 29, and a map 30 with a core position set corresponding to a shift position are provided. A stator 6 of a motor is constituted to be displaceable in an axial direction of a rotor 4 by the actuator 11, and the core position selecting circuit selects and designates the core position of the stator according to each signal of shift up/down switches SW1, SW2. The shift position is changed according to the shift up/down signals, and a core is positioned at the corresponding position. A relative distance between the rotor and the stator is set as a plurality of stages, and when one stage is selected, the control circuit controls so that the relative distance corresponding to the selected stage may be obtained by the actuator, so that the motor controller can be operated to shift a gear by switchably selecting the plurality of stages. <P>COPYRIGHT: (C)2009,JPO&INPIT |
