WIPO Patent Application WO/2019/117154
Kind Code:
A1
Abstract:
This insulator 5 comprises: a coil-winding unit 50 on which a coil 7 is wound; a first flange part 51 provided on a core segment 41 side of the coil winding unit 50, the first flange part 51 having a coil introduction groove 53 that guides the coil 7 in the coil-winding unit 50; and a second flange part 52 provided on the tip side of a tooth 42 of the coil-winding unit 50. A part 54 having projections and recesses is formed on the surface of the coil-winding unit 50, and the pitch of the part 54 having projections and recesses is less than the wire diameter of the coil 7. In a cross section view, projection parts 55 of the part 54 having projections and recesses include a side surface 55a facing the first flange part 51 and a second side surface 55b facing the second flange part 52, and the angle of inclination θ１ of the first side surface 55a is greater than the angle of inclination θ２ of the second side surface 55b.
