Slip Ring Electric Motor Soft Starter 55kw made in China

Working principles:

A special liquid resistor is connected in series to the rotor circuit of slip ring motor; the liquid

resistor get to work when the motor starts and its resistance gradually decrease during the preset

time, so as the motor can start smoothly and accelerate eventually at minimal rated current and

maximum torque. After start process is completed, the rotor circuit is shorted by the contactor.

Its low starting current results in no impact on motors, load and power system as well as in no

harmonic to affect the power system.
