Document Type and Number:
WIPO Patent Application WO/2015/037069
Kind Code:
A1
Abstract:
This invention reduces the size of a dynamo-electric machine provided with a cooling mechanism. Said dynamo-electric machine has a stator and either an inner rotor laid out radially inwards of the stator or an outer rotor laid out radially outwards of the stator. The stator has a stator core, a cooling tube that cools the stator, and a stator coil wound around the stator core and the cooling tube. In the direction of the axis of rotation of the stator, the cooling tube is laid out on the side surface of the stator core, and the section of the cooling tube that corresponds to the stator core comprises a magnetic material.
