Rotating electric machine having guide or outlets for splitting refrigerant
Abstract:
To provide a rotating electric machine capable of accurate detection of coil temperature by causing refrigerant to flow so as not to contact a temperature detecting element provided on a coil end portion. A rotating electric machine (10) comprises: a cylindrical stator core (12); coils (16) wound around a plurality of teeth (14) projecting from an inner circumferential surface of the stator core (12) and having coil end portions (18) protruding beyond respective end portions in an axial direction of the stator core (12); a cooling part (50) to cool the coil (16) by dropping refrigerant onto the coil end portions (18); and a temperature detecting element (30) placed in contact with the coil end portion (18), for detecting coil temperature. The temperature detecting element (30) is provided so as not to directly contact the refrigerant flowing on the coil end portion.
