Title:
CONTROL DEVICE FOR ROTARY ELECTRIC MACHINE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/053459
Kind Code:
A1
Abstract:
This winding-field-type rotary electric machine (40) comprises: a stator (50) including stator windings (52); and a rotor (60) having a plurality of magnetic poles that are arranged in the circumferential direction, the rotor including field windings (70) that are provided for each magnetic pole. A control device (30) is provided with a control unit that controls a stator electric current flowing in the stator windings and a field electric current flowing in the field windings, and an acquisition unit that acquires rotation parameters indicating a rotation state of the rotor. The control unit controls the magnitude of the field electric current and the phase of the stator electric current on the basis of the rotation parameters. In the case of a high-rotation state in which the rotation speed of the rotor is higher than a prescribed rotation speed, the control unit performs control such that the field electric current is higher than that in when the high-rotation state is not in effect and such that the phase of the stator electric current becomes a weakening field phase that weakens the field flux of the field windings.
