Title:
ARMATURE AND METHOD OF MANUFACTURING ARMATURE
Document Type and Number:
WIPO Patent Application WO/2021/145350
Kind Code:
A1
Abstract:
In the present invention, a multi-phase armature winding is formed by using a bundle wire including a plurality of strands (411) as a conductive wire material (CR) and winding the conductive wire material multiple times, wherein a partial winding has a pair of linear parts (401) extending linearly in an axial direction and connection parts (402) that are bent and formed on one end side and the other end side in the axial direction and connect the pair of linear parts in a circumferential direction. The linear parts are each provided in a region including portions of a coil side part and a coil end part axially divided in the partial winding among the coil side part and the second end part. The linear parts are provided with restraint parts (405) that respectively restrain the plurality of strands in the conductive wire material at positions corresponding to at least coil end parts.
