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.
liquid resistance starter performance analysis can be done, ensuring the early detection of liquid resistance starter problems and enabling corrective action to prevent damage to electrical motors, gearboxes, pinion gears and girth gear. Additionally, with clever control of the LRS dipper speed, the torque curve during starting may be

what is liquid resistance starter ball mills. liquid rheostat starter for ball millCoal Surface Mining . liquid rheostat starter for ball mill times the wound rotor motor with the liquid rheostat has come is a two stage liquid resistance starter, liquid resistant starters on ball mill - veronaschoolhouse.
The liquid starter has movable plates rather than relieing on heating to change the resistance. When starting the motor the operator monitors the stator current and manually controls the starter, keeping the stator current just below the …
The passage of the initial rotor current causes immediate partial vaporization of the electrolyte and instantaneously adjusts resistance and starting torque to optimum values. During the run-up to speed, the thermal interchanges which occur progressively decrease the resistance. A limited contactor then short circuits the low residual resistance.
