Abstract
A motor control system disclosed herein controls operation of a motor having a stator having one of an armature winding and a field winding and a rotor having the other of the armature winding and the field winding. The motor control system includes a first inverter that supplies an armature current to the armature winding, a second inverter that supplies a field current to the field winding, and a control device that controls the operations of the first inverter and the second inverter. The control device is configured to be capable of executing harmonic superimposition processing for at least partially canceling harmonics appearing in the motor by superimposing harmonic currents on the field current based on the motor operation index indicating the operation of the motor.
Claims5
A motor control system for controlling operation of a motor, wherein:
- the motor includes
- a stator including one of an armature winding and a field winding, and
- a rotor including another of the armature winding and the field winding;
- the motor control system includes
- a first inverter that supplies an armature current to the armature winding,
- a second inverter that supplies a field current to the field winding, and
- a control device that controls operation of the first inverter and the second inverter;
- and
- the control device is configured to execute harmonic superimposition processing that at least partially cancels out harmonics appearing in the motor by superimposing a harmonic current on the field current, based on a motor operation index that indicates the operation of the motor.
