Abstract
A motor control device includes: a motor that has a plurality of rotors which respectively have a magnetic piece, which drives or supplementarily drives a vehicle; a phase changing mechanism that changes relative phases of the plurality of rotors, and sets these to a predetermined induced voltage constant; and a speed control device that controls a phase changing speed of the phase changing mechanism.
Claims7
A motor control device comprising:
- a motor that has a plurality of rotors which respectively have a magnetic piece, which drives or supplementarily drives a vehicle;
- a phase changing mechanism that changes relative phases of said plurality of rotors, and sets these to a predetermined induced voltage constant;
- and
- a speed control device that controls a phase changing speed of said phase changing mechanisms,
- wherein said speed control device controls said phase changing speed in accordance with a deviation between a torque command and an actual torque for said motor, and
- wherein said speed control device controls such that said phase changing speed changes in a downward trend following an increase in said deviation.
