Electrolytic starter or Liquid Resistance Starter (LRS) to start and control the speed of a slipring motor by resistance variation. Vous devez activer Javascript dans votre navigateur afin de profiter de toutes les fonctionnalités du site Internet.
During startup, the liquid resistance starter gradually increases the voltage applied to the rotor windings of the slip ring motor. This controlled increase in voltage helps mitigate voltage fluctuations and mechanical stress. The LRS allows for a smooth and controlled acceleration of the motor, preventing excessive current surges and ensuring ...

By gradually increasing the resistance within the liquid medium, these starters ensure a smooth and controlled startup, minimizing mechanical stress and reducing the risk of motor damage. This controlled starting mechanism is particularly beneficial in applications with high-inertia loads, eliminating sudden jerks and optimizing the motor's ...
Important characteristics of Liquid Resistance Starters are the: Turn-down ratio. This is the ratio of the maximum resistance of the LRS to the minimum resistance before the short is placed in position.
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 …
