- Company Profile
In principle, the electronic regulator uses a current inner loop and outer voltage dual-loop structure, and its dynamic response is fast, for different system, it can conduct variable parameters adjustment to ensure the output of long time and max allowable torque during starting of motor and excavating, the efficiency of the excavator greatly increased. 2.In the structure, use electronic regulator for the generator excitation instead of magnetic contactor, removed the structure of swing door in the control cabinet, reduced the quantity of adjusting elements, the structure becomes simple, fault greatly reduced, the system debugging and maintenance more easy and convenient.
