Slip Ring Motor of Liquid Resistance Speeder 

Application

Applicable to three-phase ac 380V 660V, 3KV, 6KV,10KV's drag fan and pump type load of winding type of asynchronous motor soft starter speed and running, and slip changed (S≈0.1) and drag the winding rolling load of etc of asynchronous motor soft starter and inhibit surge current.

Working principle

Mainly by liquid resistors, circulation cooling device and electric control system, etc. Applied to fan and pump type load, and by adjusting the string in the accused the three-phase motor rotor circuit liquid resistance to realize stepless motor, Applied load, through the mill etc, the liquid resistance change began rolling resistance moment of suppression, reduce surge current motor temperature, protect motors.

Performance and Features

1. It has less starting current, and no impact for power grid;

2. Starting current is less than 1.3 times of rated current, to lower the capacity of transformer.

3. It can start under low voltage, the motor is assured to run normally by the power grid voltage, then starting smoothly;

4. It can work continuously for 5~10 times;

5. Starting is smooth, mechanical stress impact is little. Motors and driving machineries can be protected effectively;

6. Running energy saving rate for 20 ~ 50% (fan and pump class load);

7. Stepless speed regulating, the speed ratio about fan and pump class load is 2:1; Rolling mill load is S≤0.12.
