Abstract

The invention relates to a rotating electrical machine. A cooling structure for a rotating electrical machine includes a rotating electrical machine, a temperature sensor, and a first discharge mechanism. A plurality of discharge holes of the first discharge mechanism is disposed in a region excluding an avoidance region. The avoidance region is the same region as an arrangement region that is oneof a right side region and a left side region with respect to a vertical line passing an axis of the stator as seen in the axial direction of the stator core, the one of the right side region and theleft side region being a region in which the temperature sensor is arranged and the avoidance region is located above a lower end of the temperature sensor in the gravitation direction.

Description

technical field [0001] The present invention relates to a rotating electrical machine, which is placed with a rotating shaft intersecting the direction of gravity, and a temperature sensor is attached to a coil end protruding axially outward from an end surface on one end side of a stator core in the axial direction. For example, the rotating electric machine of the present invention is mounted on a vehicle as an electric motor for driving the vehicle. Background technique [0002] As is well known, a rotating electrical machine generates losses such as copper loss, iron loss, and mechanical loss as it is driven, and generates heat corresponding to the above losses. If the rotating electric machine becomes too hot due to the above-mentioned heat generation, deterioration of components, demagnetization of permanent magnets, and the like will be incurred. Then, in the related art, a technique has been proposed to cool the stator coil and thus the rotary electric machine by in...
