Title:
ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/075392
Kind Code:
A1
Abstract:
A rotating electric machine (10) comprises a stator (16) having a plurality of conductors (22), and a rotor (14) in which magnets (28A) are arranged along the rotation direction. The stator is provided with a plurality of flat portions extending in the axial direction of the rotation axis of the rotor on a surface facing the magnets, and further includes an inter-conductor member (57) between the conductors in the circumferential direction of the stator. The plurality of conductors are arranged along the rotation direction of the rotor at the flat portions of the stator in a configuration using, as the inter-conductor member, a magnetic material satisfying the relationship of Wt × Bs ≤ Wm × Br, where Wt is the circumferential width dimension of the inter-conductor member in one magnetic pole, Bs is the saturation magnetic flux density of the inter-conductor member, Wm is the circumferential width dimension of the magnet in one magnetic pole, and Br is a residual magnetic flux density of the magnet, or a non-magnetic material, or a configuration in which no inter-conductor member is provided.
