SENSOR MOUNTING FOR TEMPERATURE MEASUREMENT IN A MOTOR VEHICLE ELECTRIC MACHINE

A sensor-fastening means is disclosed for measuring temperature in an electric machine for the drive of a motor vehicle, having a retaining body for accommodating a temperature sensor, having a metal retaining plate, which is fastened to the retaining body and is intended for fastening to the electric machine in a defined installation position relative to the electric machine. In the installation position, the temperature sensor is oriented substantially in the radial direction of the electric machine, and has a spring element, which is supported on the retaining body and is intended for providing spring prestressing in the axial direction for the purpose of pressing the temperature sensor against a radially inner edge of a winding. The sensor-fastening means, which can be displaced in the radial direction and can be moved axially past the winding, makes it possible for the temperature sensor to be positioned on the radially inner edge of the winding from the radially outward direction and to be thermally coupled thereto with the aid of the spring element, therefore allowing easy-to-maintain and accurate measurement of a maximum temperature in a winding of an electric machine for a motor vehicle.
