Document Type and Number:
WIPO Patent Application WO/2019/039262
Kind Code:
A1
Abstract:
The objective of the present invention is to reduce the axial direction length of a stator by reducing the winding height, to achieve a reduction in the size of a rotating electrical machine. An insulator 10 includes an insulator main body 22 which covers an outer peripheral surface of a tooth 7, and an inside flange 23 and an outside flange 24 which are formed at peripheral edges at both ends in the radial direction of the insulator main body 22. A coil accommodating recessed portion 25 is formed surrounded by the inside flange 23 and the outside flange 24 on the outer peripheral side of the insulator main body 22. Extending portions 21 are provided projecting toward the radially outer side in the vicinity of both end portions 24a in the axial direction of the outside flange 24. Notched portions 26 are formed in the outside flange 24, facing both ends of the extending portions 21. A final layer 27 of a coil 8 is wound from the coil accommodating recessed portion 25 side through the notched portions 26 onto the extending portions 21.
