Title:
INSULATOR, AND STATOR AND MOTOR COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/142584
Kind Code:
A1
Abstract:
This insulator 5 comprises a first flange part 51 provided on a core segment 41 side of a coil-winding unit 50 on which a coil 7 is wound, and having a coil introduction groove 53 that guides the coil 7 to the coil-winding unit 50, and a second flange part 52 provided on the tip side of a tooth 42. A surface of the coil-winding unit 50 is provided with a movement restriction part 54 composed of an uneven part 54a, the movement restriction part 54 extending radially inward from the root of the first flange part 51. The average length of the uneven part 54a is shorter than the wire diameter of the coil 7, and the arithmetic average roughness Ra of the uneven part 54a is greater than the arithmetic average roughness Ra' of a smooth surface part 55 which is a part of the coil-winding unit 50 other than the movement restriction part 54.
