Method for testing DC motors

摘要: Disclosed is a DC parameter motor tester based on current time response, which does not require coupling of the (14) to some mechanical device or measuring other noise sensitive parameters taken from only few discrete data points. As disclosed, steady state speed determined frequency composition commutation and ripple in by performing fast fourier transform determine its power-spectral-density shows waveform giving power at each frequency. The most exists divided number twice number, depending upon construction motor, segments motor's rotation velocity measured input. are derived response points such has significant, if dominant influence.
