Title:
AXIAL GAP POLYPHASE MOTOR, STATOR FOR USE THEREIN, AND METHOD FOR PRODUCING STATOR
Document Type and Number:
WIPO Patent Application WO/2014/087831
Kind Code:
A1
Abstract:
Provided is an axial gap polyphase motor whereby losses caused by eddy current generated in the stator core can be suppressed, while preventing the stator core from shifting out of position. The stator for use in the axial gap polyphase motor is provided with: a layered stator core (1A) having a plurality of core parts (2) arranged at equal spacing in the circumferential direction and protruding in the axial direction, and a plurality of support parts (3) connecting and supporting adjacent core parts (2); coils wound onto the core parts (2); and fastener members (4) made of conductive material. Only coil parts (2) onto which are wound coils for flow of current of a single phase from among the multiple phases have a first aperture (2H) in the radial direction. The fastener member (4) is inserted into the first aperture (2H).
