WIPO Patent Application WO/2023/190566
Kind Code:
A1
Abstract:
Provided is a technology that enables improvement of the cooling performance for a coil in an electromagnetic apparatus including a core disposed in a facing manner at the outside of opposite ends in the coil winding axis direction. A claw pole motor 1 according to one embodiment of the present invention comprises: a coil 212 formed in a cylindrical shape by annularly winding a lead wire 212A having a circular cross-sectional shape; and a stator core 210 which is disposed at opposite sides of the coil 212 in the axial direction and which is formed such that inner surfaces axially facing the coil 212 are arranged in parallel to each other. The external form of the coil 212 is partially positioned at the radially inner side than in the case where the external form of a portion of the cross-section of the lead wire 212A is assumed to be a circular cross-section, and accordingly, the coil has an axial dimension smaller than that in the case where the lead wire is assumed to have a circular cross-section. Further, a portion of the lead wire 212A facing an inner surface of the stator core 210 has a planar section 212Aa parallel to the inner surface of the stator core 210.
