ROTOR TEMPERATURE it‘s too important to guess it. WHY TEMPERATURE MEASUREMENT IN THE ROTOR? 71% of the costs of an e-motor are material costs, a significant part of it for magnets (rising trend) Our experiments show: the difference between the calculated and the actual temperature of the magnets was almost 20 Kelvin. Information about the temperature of the magnets is needed to ... thermal damage to the magnets in the rotor and thus enable the use of cheaper magnets. avoid maximize the power of utilisation (avoid derating) and minimize the (thermal) reserves. improve the accuracy of the control quality and thus increase the efficiency in the driving cycle. WHAT ONLY WE CAN DO: FROM THE TEST BENCH TO THE STREET In comparison to telemetric measurement systems: No influence on the measurement by electro-magnetic disturbances of the motor No influence on the measurement by cooling oil No modification of the motor design necessary for sensor integration adaptability to the geometry of the motor/ High various sensor specifications possible. Extension of the measurement concept to include measurement Easy to integrate on the stator due to wirelessness No problem with high voltage in the winding High load capacity and reliability Application field: Automotive, Avionics, Shipping, Energy, Train
