Document Type and Number:
WIPO Patent Application WO/2021/230084
Kind Code:
A1
Abstract:
An insulator according to an embodiment of the present invention has a teeth cover part and a jumper wire guide part. The jumper wire guide part is provided with a plurality of guide walls, an extraction groove, a routing passage, and a jumper wire support part. The plurality of guide walls are able to guide the jumper wire parts of coils having mutually different phases and extracted from a plurality of divided cores, said jumper wire parts being guided in the core circumferential direction and separated by phase in the core radial direction. The extraction groove penetrates all of the guide walls in the core radial direction. The routing passage is arranged at a position separated from the extraction groove in the circumferential direction of the cores, penetrates, in the core radial direction, all of the plurality of guide walls except for an inside guide wall, which is positioned farthest to the inside in the core radial direction among the plurality of guide walls, and enables the jumper wire parts of the coil that are extracted from the extraction groove to be inserted between two adjacent guide walls among the plurality of guide walls. The jumper wire support part supports the jumper wire parts while changing the orientation of the jumper wire parts of the coil extracted from the extraction groove such that the jumper wire parts face the routing passage.
