Abstract
An apparatus for controlling a variable magnetic flux motor, wherein the variable magnetic flux motor includes a rotor in which a permanent magnet and a conductor bar are arranged, includes an inverter configured to apply a stator current to a stator coil of the motor, and a control unit configured to control a torque of the conductor bar and magnetize or demagnetize the permanent magnet by controlling the stator current through the inverter.
Claims8
A motor control apparatus for controlling a motor, wherein the motor includes a rotor in which a permanent magnet and a conductor bar are arranged, the motor control apparatus comprising:
- an inverter configured to apply a stator current to a stator coil of the motor;
- and
- a control unit configured to control a torque of the conductor bar and magnetize or demagnetize the permanent magnet by controlling the stator current through the inverter;
- wherein the control unit is configured to magnetize the permanent magnet by controlling a d-axis current of the stator current to be a positive value.
An auxiliary-motor control apparatus for controlling an auxiliary-motor, wherein the auxiliary-motor includes a rotor in which a permanent magnet and a conductor bar are arranged, the auxiliary-motor control apparatus comprising:
- an inverter configured to apply a stator current to a stator coil of the auxiliary-motor;
- and
- a control unit configured to control a driving mode of the auxiliary-motor by controlling a torque of the conductor bar and magnetizing or demagnetizing the permanent magnet according to operation of a main motor through the inverter.
