Starting resistors for mining conveyors and high-power fans!

In mining, high-power resistors are used primarily as starting resistors for mining conveyors transporting coal and for rock crushing devices.

Formerly, starting resistors were used practically in every electric drive with a wound rotor motor, as starting resistors and regulation resistors. Currently, starting resistors for wound rotor motors are no longer practically used in new drives (with few exceptions) because the design solutions of drives have changed. They are replaced by drives using frequency converters – inverters.

However, starting resistors are still produced as replacements of old cast iron resistors and spiral strip resistors on newer steel grid resistor elements and ribbon resistor elements.
