Liquid Resistance Starter What is an LRS? A Liquid Resistance Starter (LRS) – sometimes referred to as an electrolytic starter, in which the starting current of very large electrical motors is controlled by using in series with the motor-winding, a resistance consisting of an electrolytic bath through which current has to flow. The liquid acts […]

LRS Starter Introduction: In Squirrel Cage induction motor, its rotor is a squirrel cage type, there is no external resistance circuit the bars of the rotor are completely slotted. The rotor resistance is very low so that the current in the rotor is high which makes its starting torque poor. In Slip ring induction motor, it has rotor

The EPM rotor starter is normally used to control the starting of a slipring motor, and the starting current is generally limit-ed to a maximum of 250% FLC. Optimal starting torque for each applica-tion is normally selected by the choice of the initial value of resistance. The principle of the EPM starter is that the
Operating principle of Vapromatic type LRS This is based on the difference in resistivity between a liquid electrolyte and its vapour, contained in an electrode chamber. The passage of the initial rotor current causes immediate partial vaporization of the electrolyte and instantaneously adjusts resistance and starting torque to optimum values.
