Stator- Patented Rotary lamination structure

Advantages

1.Ensure the uniformity of the magnetic circuit, improve the operating conditions of the generator, and improve Generator efficiency,extending life span

2.The ventilation and heat dissipation area is increased,and the heat exchange capacity of the generator is effectively improved.Good ventilation and heat dissipation

Rotor-Enameled flat copper wire rotor winding

Advantages:

1.Insulation strengthening treatment for the first and last three turns of each pole coil of the generator rotor can significantly increase the resistance of the pole coil to voltage shock and improve the generator’s life span and reliability;

2.Reduce the impact on the rotating rectifier bridge and improve the service life and reliability of the rectifier bridge;

3.Reduce the excitation current design can effectively improve the reaction speed of excitation,reduces the output current of the AVR and improves the sensitivity and service life of the AVR.
