Title:
ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/281898
Kind Code:
A1
Abstract:
A rotating electric machine (10) comprises: a stator (14) having a cylindrical stator core (16); and a rotor (15). The stator core (16) has a cylindrical yoke (30) and a plurality of teeth (31) extending from the yoke (30) to the inside in the radial direction. The rotating electric machine (10) further comprises a heat transfer member (50) thermally connected to the stator core (16). The heat transfer member (50) has a resin portion (51) and a high thermal conduction portion (52) that is held to the resin portion (51) and has a higher thermal conductivity than the resin portion (51). A housing (11) has a facing portion (13) that is a region facing an end surface of the stator core (16). The high thermal conduction portion (52) extends from between the teeth (31) adjacent in the circumferential direction toward the facing portion (13) and projects from the end surface of the stator core (16).
