Title:
ROTATING ELECTRICAL MACHINE AND DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/107372
Kind Code:
A1
Abstract:
One embodiment of this rotating electrical machine comprises: a rotor that can rotate around a central shaft; a stator with a stator core located on the radially outer side of the rotor; and a tubular refrigerant supply section, with a supply port that supplies a refrigerant to the stator, that extends in the axial direction of the central shaft. The refrigerant supply section has a wide section that is located on the radially outer side of the stator. The wide section has at least one supply port, and the circumferential-direction dimension of the wide section is greater than the radial-direction dimension thereof.
