This generator used in 1500kW VSCF wind turbine. In order to achieve the purpose, Stator connected with the grid,the rotor of the motor was controlled through the transducer.The motor adopt winding rotor structure, cooling air-to-air cooling for hybrid ventilation. And special high-performance silicon processing channel in order to reduce harmonics, improve motor performance. After strict testing, the productions are reaching the level of similar foreign motor on the excellent performance. Rated power 1550KW Rated speed 1755 r/min Speed range 975 1970 r/min Stator rated voltage 690V±10% Stator rated current 1115A Rotor rated voltage 320V Rotor rated current 430A Winding connection Y / Y Power factor 0.95 (Lead) 0.95Lag Protection class IP54 Insulation class H Work mode S1 Installation mode IM B3 Cooling mode Air cooling Center high 500mm Pole number 4 Weight 6950kg
