Title:
COOLING STRUCTURE OF ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2016144271
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To efficiently cool down a coil.SOLUTION: The cooling structure is so configured that a stator 1 is formed by winding a coil 5 around a tooth 3, protruding from an annular yoke 2, a thermal conductor 7 is molded with resin of a high thermal conductivity to both side faces in a shaft core direction of the stator 1 while filling between the coils 5 of the teeth 3, and a passage 8 for coolant circulation, is formed inside the thermal conductor 7. The coil 5 is wound by concentrated winding around the tooth 3 through an insulating member 4 made of an elastic resin. The passage 8 for coolant circulation, is disposed by being overlapped with the coil 5.SELECTED DRAWING: Figure 1
