Liquid starter - Electric motors & generators engineering ...

The motor drives a cement ball mill, and the operator is blaming the starter but I think that if it is not accelerating as it used to then the load has increased. Any thoughts? Also the starter used soda ash (sodium carbonate) to modify the conductivity fo the water, does any one know what the chemistry of the liquid should be?

STEPPING FORWARD: USING VARIABLE SPEED DRIVES …

The use of VSDs makes it very easy to set the mill speed by just modifying this value on a touchscreen. But this is not only an option for new installations. In installations where SAG and Ball mills have been working for several years at fixed speed, but the speed regulation has been observed to be necessary VSDs can also be integrated very ...

Liquid-cooled starters - GINO AG

Therefore, Liquid Resistance Starters ( LRS) are commonly used to start up WRIM motors in industrial environments. 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.
