Abstract

The disclosure relates to a temperature monitoring assembly for monitoring the windings of a motor, comprising at least one temperature sensor or thermal circuit breaker arranged outside of and spaced from the windings of the motor, and at least one heat conducting component, which extends from a first component section for heat coupling and heat transfer, which is in contact with or adjacent to the windings, to a second component section for heat coupling and heat transfer, on or adjacent to the temperature sensor.

First claim

What is claimed is:

1. A temperature monitoring assembly for monitoring windings of a motor, comprising:
at least one temperature sensor or thermal circuit breaker arranged outside of and spaced from the windings of the motor,
and at least one heat conducting component which extends from a first component section for heat coupling and heat transfer which is in contact with or adjacent to the windings, to a second component section for heat coupling and heat transfer, on or adjacent to the at least one temperature sensor, wherein
the at least one heat conducting component is a conductive plate, embodied as a metallic stamped and bent component that is folded back upon itself.

2. The temperature monitoring assembly according to claim 1 , wherein the heat conducting component has a thermal conductivity of λ>200 W(m K).

3. The temperature monitoring assembly according to claim 1 , wherein a funnel-shaped mounting device is further provided, into which the first component section of the heat conducting component is inserted.

4. The temperature monitoring assembly according to claim 1 , wherein the first component section of the heat conducting component is embodied as a section of the heat conducting component that is bent substantially into a V-shape.

5. The temperature monitoring assembly according to claim 4 , wherein the V-shaped section extends in the space between two windings of the motor.

6. The temperature monitoring assembly according to claim 1 , wherein a heat conducting film covers the at least one temperature sensor is arranged between the temperature sensor and the second component section of the heat conducting component.

7. An electric motor with the windings, which is equipped with at least one temperature monitoring assembly according to claim 1 .

8. The electric motor according to claim 7 , wherein the at least one temperature sensor is mounted spaced from the windings on a conductive plate or a sensor mount, and the heat conducting component is arranged with its first component section between the windings and with its second component section above the temperature sensor.
