Electrolytic starter (LRS) for high power slipring motors
AOIP starters for slipring motors, also named electrolytic starters or Liquid Resistance Starters (LRS), use mobile electrolytic resistances. Each starter is made of 3 tanks (one per phase) filled with conductive liquid named electrolyte (water mixed with salt, usually Sodium Carbonate) and two immerged electrodes.

6.6kV Slip Ring Induction Motor Liquid Starter
We have five liquid starters and have been in operation since circa. 1970 without and significant issues. The original manufactures (Allen West) documentation Leaflet 909/A/3 that states “Neutral or Star point is earthed, so that the rotor slip rings must be insulated from earth” In this case the motor winding are insulated from earth.

Rotor current measurement of motors
Rotor current will be directly proportional to torque and stator current. In affect you could measure the stator current and calculate the approx rotor current. very typical for a ball mill or sag mill as Chris mentioned. The liquid starter simply adds resistance in the rotor during starting to produce torque and depending on the

Lrs Principle
Posted August 9, 2009. There are two ways a Liquid Resistance Starter can be used. 1) as a primary resistance starter where the resistance is connected in series with the stator of a standard squirrel cage motor and. 2) as a secondary resistance starter where the resistance is connected in series with the rotor of a wound rotor motor.

The Rotor Starter is designed in such a way that the resistance offered by it is frequency dependent. When the motor starts from zero speed the rotor frequency equal to supply frequency and the Rotor Starter resistance is maximum. Salient Features: Slip dependant Resistance provides automatic resistance variation during acceleration.
