Document Type and Number:
Japanese Patent JP4998450
Kind Code:
B2
Abstract:
A stator includes an annular stator core (141) formed by annularly arranging a plurality of split stator cores (175) and a coil (180) mounted on the stator core (141). Each split stator core (175) includes a yoke portion (176) extending in a circumferential direction of the stator core (141) and a stator tooth (171) protruding from the yoke portion (176). On least part of side surfaces (193) of the stator tooth (171) that are arranged in a circumferential direction of the stator core (141), a radial end surface (192) of the stator tooth (171) that is located radially inward of the stator core (141), and, of radial end surfaces (198, 199) of the yoke portion (176) that are arranged in a radial direction of the stator core (141), the radial end surface (198) at which the stator tooth (171) is formed, a rough surface portion is formed having surface roughness greater than that of circumferential end surfaces (190, 191) of the yoke portion (176) that are located in a circumferential direction of the stator core (141).
