Pośredni pomiar elektromagnetycznego momentu silnika indukcyjnego

The principle assign of slow variable induction motor torque based on power measurement taken by motor was briefly presented in the paper. Sample waveforms of motor load torque received of based on registered waveform input power were shown. It seems that in case of high-power driver, which continuously registration electrical quantity such as power or current input is currently often applying, registration of slow variable load torque can be comfortable to assessment of motor work.
