A device for measuring the temperature of a coil device in an electric machine having a temperature sensor, a first section which produces a first restoring force, a second section which receives the temperature sensor, a third section which has a first fixing element, and a fourth section which produces a second restoring force. The first restoring force and the second restoring force act in a common direction, and the second section is arranged between the first section and the fourth section.

Attachment of a temperature sensor to an interconnection ring of an electric machine

The disclosure relates to a sensor fastener for measuring a temperature on a busbar assembly with a busbar, said assembly has at least one busbar assembly with at least one busbar. One or more busbars have bending elements, each of which has a free end; and a connecting ring for connecting to the busbar assembly. The bending elements extend through the connecting ring such that the free ends are free-standing in such a manner that the temperature of the free ends can be measured by a temperature sensor, thereby allowing a precise measurement of the temperature in a winding of an electric machine for a motor vehicle.

Sensor fastener for measuring a temperature in an electric machine of a motor vehicle

A sensor fastening device for temperature measurement in an electrical machine for driving a motor vehicle having a retaining body for receiving a temperature sensor, a support body for resting against a stator lamination of the electrical machine, the support body being connected to the retaining body spreadably, and a spreading element for spreading the retaining body away from the support body. By means of the sensor fastening device, which can be shifted in the radial direction and can be moved past the winding axially, the temperature sensor can be positioned, from the radial outside, on the radially inner edge of the winding and can be thermally coupled by means of the spreading element such that maintenance-friendly and accurate measurement of a maximum temperature in a winding of an electrical machine for a motor vehicle is made possible.
