Abstract
Official abstract text for this publication.
A stator includes a core having a yoke having an annular shape, and teeth protruding toward a center of the yoke and provided at predetermined intervals in a circumferential direction of the yoke, a coil disposed to surround the teeth, a power line connected to a coil end portion of the coil, protruding in an axial direction of the core, and having one end and the other end, the power line having a terminal portion connected to the other end opposite to the one end connected to the coil end portion, a bent portion bent to extend in a predetermined direction, and a coating portion coating the bent portion over both ends of the bent portion, and a mold portion surrounding the coil end portion and integrally surrounding the coil end portion, the one end of the power line, and at least part of the coating portion.
First claim
Opening claim text (preview).
What is claimed is: 1 . A stator comprising: a core having a yoke having an annular shape, and teeth protruding toward a center of the yoke and provided at predetermined intervals in a circumferential direction of the yoke; a coil disposed so as to surround the teeth; a power line connected to a coil end portion of the coil, protruding in an axial direction of the core, the power line having one end and another end, the power line having a terminal portion connected to the other end opposite to the one end connected to the coil end portion, a bent portion bent so as to extend in a predetermined direction, and a coating portion coating the bent portion over both ends of the bent portion; and a mold portion surrounding the coil end portion, the mold portion surrounding the coil end portion, the one end of the power line, and at least part of the coating portion together, wherein the coating portion includes at least one of a heat-shrinkable tube and a heat-seal tube, coating the bent portion and the one end. 2 . The stator according to claim 1 , wherein the coating portion is provided by insert molding with the bent portion and the one end. 3 . The stator according to claim 1 , wherein: the power line has a plurality of the bent portions between the one end and the other end; and the coating portion includes one of the plurality of bent portions, closest to the one end.
