Document Type and Number:
WIPO Patent Application WO/2016/006310
Kind Code:
A1
Abstract:
A stator coil that is mounted to a stator slot by winding in a concentrated manner, said stator coil comprising a winding section in which a conductor is wound one pitch at a time around the stator teeth and a connection terminal section that extends from both end parts of the winding section. The winding section comprises a plurality of unit winding sections having a rectangular ring shape. The unit winding sections comprise a pair of first linear sections, a pair of second linear sections, and a curved corner section that connects the first linear sections and the second linear sections. An inclined section that is offset from the conductor by one pitch in the winding axis direction is formed on one of the pair of first linear sections. A part of the inclined section is configured from a part of the curved corner section in at least one unit winding section.
