Title:
ROTATING ELECTRIC MACHINE AND ROTATING ELECTRIC MACHINE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/073799
Kind Code:
A1
Abstract:
This rotating electric machine is a permanent magnet rotating electric machine and is provided with: a rotatably supported rotor (12); and an armature (13) disposed coaxially with the rotor and having an armature winding (23) wound therearound, said armature winding being energized by multi-phase AC current. The rotor has: a plurality of permanent magnets (32) magnetized in the radial direction and provided at positions separated from each other in the circumferential direction so that the poles facing the armature alternately become N-pole and S-pole; and a yoke member (34) formed of an iron core material, connecting the side surfaces of the permanent magnets in the circumferential direction to each other between the permanent magnets adjacent in the circumferential direction, and annularly connecting the permanent magnets. Phase control of the energization of the armature winding makes it possible to change the magnitude of a field flux directed from the permanent magnets to the armature.
