Wound Rotor Induction Motor with Liquid Rheostat Arcing ...

Sep 18, 2011  We operate ball mills with dual-coupled 3500hp 4160v wound rotor induction motors. We have recently experienced frequent arcing of the slip rings which seems to start on the center ring. The arcing damages the ring badly which requires us to shutdown the mill to sand it smooth again.

Electrolytic starter (LRS) for high power slipring motors ...

The level variation of electrolyte is pretty slow, which does not enable resistance to vary quickly enough for some specific applications (control of the slip for the ball mills for example). Why using a starter for slip ring motors. In order to start a slip ring motor, the accelerating torque has to be sufficiently higher than the resisting ...

Starting of slip ring induction motor explained in an easy ...

Low starting current when compared to squirrel cage induction motors, 3. Speed is varied with the help of external resistance, from 50% to 100% of the full speed, 4. Higher brush and slip ring maintenance required, 5. As the brush wears out, it may lead to intermittent contact, and thus heavy sparking. Thus we have seen in detail the starting ...
