CONTROLLER AND CONTROL METHOD FOR ROTARY ELECTRIC MACHINE
First Claim
1. A control unit for a rotary electric machine, the control unit being applied to a rotary electric machine which comprises a rotor having a field winding and a stator having an armature winding to control a field current passed through the field winding, wherein:
- the armature winding is applied with a prescribed voltage; and
the field current controlled so as to be a first field current with which a deviation between an amplitude of an induced voltage generated in the armature winding by rotation of the rotor and an amplitude of the applied voltage of the armature winding becomes equal to or smaller than a prescribed value.

Abstract
There is provided a control unit (40) applied to a motor (10) that includes a rotor (12) having a field winding (11) and a rotor (13) having armature winding groups (10a, 10b) to control a field current passed through the field winding. Each of the armature winding groups is applied with a prescribed voltage. The field current is controlled so as to be a minimum field current value If_min with which a deviation between an amplitude of an induced voltage generated in the armature winding groups by rotation of the rotor, and an amplitude of the voltage applied to the armature winding groups becomes equal to or smaller than a prescribed value.
