Document Type and Number:
WIPO Patent Application WO/2019/004117
Kind Code:
A1
Abstract:
This stator is provided with a stator core, an insulator, and a plurality of coil wires. The insulator has an outer wall portion that is located just above the core back and extends in the circumferential direction. A first cutout that extends from the upper end to the lower side is provided in the outer wall portion. A first protrusion that protrudes radially outward is provided to the outer side surface of the outer wall portion. A bottom surface directed toward the upper side of the first cutout is located on the upper side relative to the lower surface of the first protrusion. A pair of jumper wires among the coil wires are lined up vertically along the outer side surface of the outer wall portion on the radially outer side of the outer wall portion, and extend in the circumferential direction. Of the pair of jumper wires that are lined up vertically, one is determined as an upper-side jumper wire and the other that passes along the lower side of the upper-side jumper wire is determined as a lower-side jumper wire. The upper-side jumper wire passes through the first cutout and is drawn radially outward of the outer wall portion. The lower-side jumper wire passes just below the first protrusion.
