  • Wound Rotor Induction Motor with Liquid Rheostat Arcing

    Sep 18 2011 · We use liquid rheostats on all of them not only to start but also during operation to control incoming line current when the motor sees heavy loads (automobile shredding). A couple of years ago I had one motor that continually ate brushes on one phase (middle ring) and also experienced several damaging arc flashes.

    I suspect that dust is your culprit. I had a similar problem in a sawmill with a lot of fine dry dust in the air. The dust builds up in the brush hI suggest you check the liquid resistor solution concentration the connections contacts between the resistor slipring shorting contactor.Thanks for the advicewe will change our PM procedure to more thoroughly clean the brushes and holders. We had been pulling on the brush wire toThe dust it is obviously a source of brush damage. I think the dust also could damage the rings too. It could be a shaft eccentricity also. I wandeHigh rotor current could be the problem from your explanation I infer that a step resistor is used for starting verify correct connections in finQuote Something I noticed was that the brush wires "jump" and sometimes arcing is observed when the shorting contactor pulls in after the liquid rQuote (waross) A current surge is normal when the shorting contactor pulls in.
