Document Type and Number:
WIPO Patent Application WO/2019/049761
Kind Code:
A1
Abstract:
A first inner peripheral surface (122) on the inner side (X2) in a radial direction (X) of a first flange portion (121) of a back yoke portion (12) is formed on the outer side (X1) in the radial direction (X), except for an end point (151), of a virtual plane (S) which passes through the end point (151) at an abutting end (15) of the first flange portion (121) and which is orthogonal to side surfaces (131) on both sides in a circumferential direction (Z) of a tooth portion (13). An insulating sheet (5, 50) is mounted to the side surfaces (131) of the tooth portion (13). An insulating resin portion (4) covers both end surfaces in an axial direction (Y) of the tooth portion (13), the first inner peripheral surface (122) of the first flange portion (121), and a second outer peripheral surface (142) of the second flange portion (141). The tooth portion (13), the back yoke portion (12), and the insulating sheet (5, 50) are integrally molded. A winding body (8) is formed of a winding wound around the tooth portion (13) with the insulating sheet (5) and the insulating resin portion (4) disposed therebetween.
