Embodiment Construction
[0038] Figures 1 to 6 A temperature sensor unit 1 is shown, at least in part, for an electric motor 2 (electrical machine) of a motor vehicle (electrical machine), which is likewise not shown in detail here, but is at least partially schematically shown, of a motor vehicle not shown in detail here.
[0039] The temperature sensor unit 1 has at least one temperature sensor 3 and at least one fastening unit 4 . The temperature sensor unit 1 can be arranged on the electric motor 2 or on the housing 5 of the electric motor by means of the fastening unit 4 , which is designed in particular like a flange. In this case, the temperature sensor 3 is operatively, in particular indirectly, connected to the fastening unit 4 , which will be explained in more detail below. The temperature of the winding 6 of the stator 7 of the electric motor 2 , in particular the winding head 6 a , can be determined by means of the temperature sensor 3 . The electric motor can be used in particular in h...

The invention relates to a temperature sensor unit used for an electric motor, especially for a motor vehicle. The temperature sensor unit is provided with at least one temperature sensor and at least one fixation unit. The temperature sensor unit can be configured at a shell of the electric motor by virtue of the fixation unit and can be effectively connected with the fixation unit. Temperature of a winding of a stator, a winding head in particular can be measured by temperature sensors. Lower assembly cost and better precise measurement of temperature make movable configuration of the temperature sensors relative to fixation units possible. Due to at least one elastic component and configuration and / arrangement, the fixation units can be configured on at least one contact surface of each temperature sensor behind the shell of the electric motor and to be in contact with a matching contact surface of the winding. Owing to elastic force of action, continuous contact among the contact surface of the temperature sensors, the winding, and the winding head in particular can be achieved.
Description
technical field [0001] The invention relates to a temperature sensor unit for an electric motor, in particular for a motor vehicle, according to the features of the preamble of claim 1 . Background technique [0002] Various temperature sensor units are known in the prior art for electric motors, in particular for motor vehicles. Such a temperature sensor unit has at least one temperature sensor and in particular also a fastening unit (for fastening the temperature sensor unit on the housing of the electric motor). [0003] A temperature sensor unit for an electric motor / electrical machine of a motor vehicle is described in DE 10 2013 000 949 A1, from which the present invention is based, wherein the temperature sensor unit has a temperature sensor and a temperature sensor unit. The temperature sensor unit can be arranged on the housing of the electric machine by means of the fastening unit. For this purpose, the fastening unit is designed flange-like and has a socket exte...
