Induction motor powered by frequency converter may require additional testing following a fault identified as a stator related anomaly. If the inner phase insulation is damaged or weak, the rapid voltage rise seen from many frequency converters can result in inner phase currents sufficient to cause the frequency converter failure. This article is designed to give the analyst additional motor circuit evaluation ...

Frequency converters are now finding wide use in mining applications. Most of these frequency converters use adjustable frequency outputs that are produced by rectifying the AC power supply to DC and then inverting this DC voltage back into AC using a high frequency carrier and pulse width modulation (PWM) to produce adjustable frequency, adjustable voltage supply to the motor. ...

I have a doubt that if we are using static frequency converter then we can start with giving low frequency to the stator... and if the frequency is low then can magnetic locking between stator and rotor can take place directly (without excitation) and after that we can increase the frequency to stator & after reaching say 75% speed the turbine will be self-sustaining and the static frequency ...
