Contact sensor ring

Basic inforrmation

Up to 3 sensors monitor the temperature of motor windings during high thermal stress.

Applications

  • For temperature control in electric motors
  • Sensor assembly in a one-piece reception unit

General function

In close thermal contact to the motor winding, the thermal sensors measure the temperature of the winding in up to 3 motor phases.
When the temperature limit is exceeded, the sensor resistance also changes. This resistance change is processed by downstream electronics.

Advantages

  • Unit integrated with electric motor
  • Sensors are completely interchangeable against the same type or different types of temperature sensors
  • Non-destructive exchange without disassembly tools
