Anyone here can suggest to me how to measure harmonic and total harmonic distortion from a induction motor controller? I can see the distorted waveform through the oscilloscope and the FFT.
But the thing I required must be very detail, for example, the value of 3rd harm, 5th harm, 7th harm and...
Dear All,
Recently, I try to collect a set of data from PWM controller that control the speed of a three-phase induction motor. The problem is how to measure the efficiency of the motor. It's related with the electrical power input and mechanical power output. That's no clear description...
