Document Type and Number:
WIPO Patent Application WO/2020/246372
Kind Code:
A1
Abstract:
The problem addressed by the present invention is to efficiently cool a rotor coil even in a rotor provided with a wiring board. The present invention is a stator of a dynamo-electric machine, wherein said stator comprises: a stator core; a plurality of segment coils that protrude from slots of the stator core, and are aligned in the radial direction; connection conductors that interconnect the segment coils; and an insulation member that holds the connection conductors. The insulation member has through holes through which the segment coils pass and are accommodated in, and openings through which coolant can flow into the through holes are provided on the inner circumference side of the insulation member.
