Therefore, liquid resistance starters LRS are commonly used to start up WRIM motors. For liquid starters, the electrolyte solution of Na2CO3 or K2CO3 acts as a resistor, with the resistivity, in turn, depending on the soda concentration. By changing the distance between the upper and lower electrodes, the resistance is reduced smoothly.
