Resistance Box

Product Details:

Braking resistor are used in the D.C. link of the frequency converter. a braking chopper activates the resistor. if the output frequency converter drops-be it by a control process, a drop in speed or a braking operation-below the current operating frequency of the motor, the motor takes on the function of a generator./ the consequences is arise in the link voltage. if this voltage exceeds the specific value of the unit in question, chopper the specific value of the unit in resistor. if the voltage drops to a value just above the grid voltage of the link, the chopper will interrupt the circuit. this process will be repeated until the motor speed once again matches the applied operating frequency. the braking resistor takes on the energy and converts it into heat.

Product Details:

Resistance boxes are used to add resistance into an electric motor circuit for modifying the performance characteristics of slipring induction motor of eot cranes,rubber mills, steel rolling mills, cement mills, power plants, conveyors, coke oven, blowers etc. for speed control and developing starting torque with low starting currents. they are also used as dynamic braking for Vvvf Ac drives, electric loading of Ac alternators, degenerators and dynamometers. resistors are designed to meet requirements of both A.c and D.c. applications.
