Measuring resistances in electric motors

for vehicle hybrid drives

  • Resistance measurements in range 30 ... 50 mΩ at 0.03 % of measured value
  • Temperature coefficient taken into account
  • Protection against high induced voltages
  • Thermal-EMF compensation
  • PC port

Task

Very high accuracy is required for measuring the winding resistances of electric motors. It is important that the three windings are symmetrical, and resistance values typically equal around 40 mΩ. In this situation, care must also be taken to make proper contact with the connecting studs to avoid contact resistances.
