Measurement of the Friction and Cogging Torques

Friction and Cogging Analysis in Traditional Mode for Brushless Motors, suitable for Customers which want/need to couple the motor in test with an Active Brake also in Production.


With this test, performed with the traditional method of setting in rotation the brushless motor not powered using a suitable active brake, on the signals acquired is performed a suitable FFT Spectral Analysis and the following data are acquired:

  • Friction Torque; 
  • True RMS Cogging Torque in a programmable bandwidth.
