Title:
IN-WHEEL MOTOR
Document Type and Number:
Japanese Patent JP2017169326
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an in-wheel motor that can maintain contact condition in which the in-wheel motor contacts with a stator and a motor case by being deformed following fluctuation of a gap between the stator and a moro case so as to be capable of improving radiation performance.SOLUTION: An in-wheel motor includes a heat conduction member 4 which is disposed at a gap 5 between an outer peripheral surface of a stator 2 in a radial direction and an inner peripheral surface of a motor case 1, and contacts with the stator 2 and the motor case 1 to perform heat conduction. The heat conduction member 4 is formed like a corrugated sheet configured by alternatively continuously forming an outer diameter crest part 41 which is a convex in an external diameter direction and contacts with the motor case 1 and an inner diameter crest part 42 which is a convex in an inner diameter direction and contacts with the stator 2. A slit 44 is formed at at least one of both crest parts 41, 42, which extends in a direction crossing the projection direction.SELECTED DRAWING: Figure 4
