Electrolytic starter LRS for high power slipring motors EPM Aoip. The EPM rotor starter is normally used to control the starting of a slipring AOIP starters for slipring motors also named electrolytic starters or Liquid Resistance Starters cylinders which merge with each other in the minimum resistance position some specific applications control of the slip for the ball mills for example

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.

06/23/2011 6:05 AM. Dear all, kindly suggest for a suitable starter to start a ball mill with 2600 kw, 1000 rpm, 11 kv slipring induction motor. has any latest technology invented to start the motor other than LRS & FCMA. can the VVFD solution fullfil the initial torque compansation. the GD2 value of mill is around 400 kg m2.

I've got a 500kW, 6.6kV slip ring induction motor, which uses a liquid starter to bring it up to speed and is then switched to synchronous operation. The starter has movable plates rather than relieing on heating to change the resistance.

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 ...

This liquid Rheostat is a Salt Water Rheostat and is controlling the rotor on a 6500HP Ball Mill Motor. I thought there was both voltage and current on the Rheostat when up to full speed. Thanks for the confirmation.
