Method for safe electrical separation of temperature-sensitive sensors in an electrical motor uses sensors operating through connector wires with extra-low voltage and stator coils for an electric motor operating at low voltage.

摘要

Sensors operate through connector wires (3,4) with extra-low voltage. Stator coils for an electric motor operated at low voltage. The sensors are positioned in the stator coils in such a way that they have low heat transmission resistance to the stator coil's wires. Reinforced or doubled insulation on the sensors' side and the connector wires' side provides for safe electrical separation opposite higher-voltage stator coils.
