WIPO Patent Application WO/2017/098865
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing motor housings 3L, 3R having a high cooling effect, wherein multiple flow paths circulating a coolant are arranged in parallel, without using a core 52 having a complex shape. Multiple separate C-shaped flow paths are provided in parallel in the interior of cylindrical motor housing main bodies 3aL, 3aR, openings 54a-54d which open on the outer periphery of the motor housing main bodies 3aL, 3aR are provided at the ends of the separate C-shaped flow paths, a lid member 56 covering these openings 54a-54d is affixed to the motor housing main bodies 3aL, 3aR, and a linking flow path 60 connecting the opening 54b of one flow path and the opening 54c of one adjacent flow path is provided in the inner surface of the lid member 56. Thus, it is possible to mold the motor housings 3L, 3R by using the C-shaped core 52.
