Therefore, Liquid Resistance Starters (LRS) are commonly used to start up WRIM motors in industrial environments. For liquid starters, the electrolyte solution of Na 2 CO 3 acts as resistor, which in turn depends on the soda concentration. By changing the distance between upper and lower electrodes, the resistance is reduced smoothly.

Oil- cooled starters are stepped resistance starters with 3PR3 cast iron resistors in a tank filled with mineral based insulating oil. GINO AG acquired the 3PR3 series from Siemens in the year of 2000. The oil-cooled starters store the heat dissipated during the starting process and slowly release it to the atmosphere via the tank surface.
