Liquid-cooled starters - GINO AG – Elektrotechnische Fabrik

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. In addition, the fluid acts as a store of heat energy, which occurs during start-up, and this is slowly released to the ...

TECO-Westinghouse Wound Rotor Motors

Wound Rotor. Wound rotor motors are an extremely versatile breed of induction motors. Featuring a rugged design, these machines provide the unique ability to gradually bring up to speed high-inertia equipment and large loads smoothly and easily. Wound rotor motors also can develop high starting torque at standstill – while maintaining low inrush.

Wye-Delta Starters vs Softstarters | Mike Holt's Forum

The ball mill when loaded had a very large initial intertia and it needed a high initial starting torqure which was provided by a Liquid Rheostat. Depending on the rate at which the resistance in the Rheostat would change would affect the starting time of this motor and load.

CHOOSING A SUITABLE RHEOSTAT : - Reostatos Sumintec Arecheta

To choose a suitable rheostat for getting a soft start of an electric motor, it must be taken into account the following: 1. The engine power must be less powerful than the maximum starting power indicated on the rheostat. This is directly related to the volume of water. The more water the rheostat contains, the more heat it can absorb.

What is a Liquid Rheostat?

Design of Liquid Rheostats Design factors for liquid rheostats include the type of electrolytic fluid used, the volume of fluid used, the heat dissipation method implemented, and the AC motor power. These factors are determined by the application for the liquid rheostat. Most modern liquid rheostats have a low-conducting stainless steel tank (often
