Title:
ROTATING ELECTRIC MACHINE ROTOR AND METHOD FOR ASSEMBLING ROTATING ELECTRIC MACHINE ROTOR
Document Type and Number:
WIPO Patent Application WO/2020/152776
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a rotating electric machine rotor in which a partition can be easily formed that prevents the protrusion of an adhesive agent for bonding a permanent magnet from flowing into a portion to which a permanent magnet adjacent to the permanent magnet is bonded, and also provide a mehod for assembling the rotating electric machine rotor. The rotating body (6) of the rotor (5) of the rotating electric machine (1) has protrusions (8) at equal intervals in the circumferential direction, said protrusions (8) extending in the axial direction. The rotating body (6) is provided with partition grooves (9) going around the side in the circumferential direction. A plurality of attachment surfaces (10) are partitioned by the protrusions (8) and the partition grooves (9). Partition plates (11) each have a plurality of partition pieces (12) each having an arc-like shape. The partition plates (11) are provided over the entire periphery of the partition grooves (9). The partition plates (11) project from the side of the rotating body (6) in the radial direction. A plurality of permanent magnets (7) are bonded to the respective plurality of attachment surfaces (10) by an adhesive agent.
