Predictable: The whole starting process of the motor and its driving equipment can be simulated by special computer simulation software. The starting performance of the motor can be analyzed in advance, and the best starting curve can be obtained.
Adjustable: starting time, liquid resistance and other parameters can be randomly adjusted according to the actual conditions of the site;
Controllable: The liquid resistance value can be set according to the optimal electromagnetic torque and minimum starting current of the controlled motor, and the starting process is completely controlled, thus the voltage drop of the power grid is also effectively controlled.
Repeatable: Initial resistance of liquid resistance can be automatically detected and corrected according to ambient temperature and last starting liquid temperature to ensure consistency and stability of starting performance when starting again.
