Problems solved by technology

Therefore, there is a technical problem that the force with which the temperature sensor is pressed by the coil conductor varies even if the coil conductor is pressed with the same force due to the difference in the opening amount of the bent portion before the temperature sensor is inserted and the difference in the hardness of the coil conductor. , due to the inability to fully press the temperature sensor, the installation position of the temperature sensor relative to the extension direction of the coil conductor is shifted
[0009] In addition, there are technical problems as follows: due to the deviation of the installation position of the temperature sensor, the measured temperature of the stator coil is deviated, the accurate temperature of the stator coil cannot be measured, and the reliability of the temperature se

Abstract

A rotary electric machine suppresses the deviation of the installation position of a temperature sensor and the deformation of the temperature sensor so as to improve the reliability of the temperature sensor and the rotary electric machine. Comprises: a rotor having a field core wound with a field winding; the stator is provided with a stator iron core and a stator coil; the temperature sensor is used for detecting the temperature of the stator coil; and an attachment member that attaches the temperature sensor to the stator coil, a portion of a coil conductor extending linearly of the stator coil being recessed in a direction orthogonal to an extending direction of the coil conductor, and having a recessed portion in a surface of the coil conductor. The sensor portion of the temperature sensor is disposed on the side of the coil conductor where the recess is provided, and the mounting member has the sensor portion of the temperature sensor embedded therein and has a protruding portion abutting against the recess.

Description

technical field [0001] The present application relates to a rotating electric machine. Background technique [0002] A rotating electrical machine includes a rotor and a stator having a stator core and stator coils. The rotating electrical machine operates as an electric motor that drives the internal combustion engine, and the rotating electrical machine functions as a generator that is driven by the internal combustion engine to generate electricity. When the rotating electric machine operates as a motor, current flows through the stator coils. At this time, when the stator coil generates heat due to the current flowing through the stator coil, the temperature of the stator coil rises. If the temperature of the stator coil rises excessively, the stator coil and components provided around the stator coil may be damaged. Therefore, a temperature sensor that detects the temperature of the stator coil is installed in the stator coil, and the current flowing to the stator co...
