Title:
MULTILAYERED WOUND COIL, STATOR, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/001736
Kind Code:
A1
Abstract:
Disclosed are a multilayered wound coil, a stator, and a manufacturing method therefor. The stator is provided with: a stator core comprising laminated steel sheets; and a coil which is wound around a teeth section formed on the stator core and has a plurality of layers formed in the circumferential direction of the stator core. The winding of the coil proceeds in either the radial direction or the circumferential direction of the stator core, whichever direction has fewer adjacent conductors, and doubles back at the end in said direction. This reduces the difference in potential between adjacent conductors, making it possible to ensure insulation between adjacent conductors even with a thinner insulating film.
