1 ) General introduction: 

1:smooth start, without shook to equipment, extend the using life,save equipment maintain cost

2:reduce start current 1.3times, reduce  temperature increasing of motor, largely extend  the long of motor,

3:can start in lower rated voltage

4:free maintenace, full protect to motor

 

2)operating principle:

  **For wound rotor asynchronous motor, when the grid voltage and frequency are invariant,

    the connection of the starting resistor  to the rotor loop will reduce the starting current

    and get a larger  starting torque.

  

  **putting special compound electrolyte into the rotor loop of the  controlled winding motor as

    the liquid resistance, when the stator receive the signal of the motor starting,  it will change

    the location of the electrolyte automatically, so as to reduce the resistance value gradually.

 

  **when the resistance reached the minimum level, the sensor closed and motor rotor star

     connected  directly, then the equipment start smoothly with a low current, large torque.
