Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing.
[0025] Such as figure 1 As shown, a wind power generator variable pitch system transmission system using the method of the present invention, the output shaft of the low-speed high-torque permanent magnet motor 1 is directly connected with the wind power generator variable pitch transmission shaft system 3 through the coupling I2, and the wind power generator becomes The pitch drive shaft system 3 is connected to the blade roller 5 through the coupling II4, and the direct drive of the blade roller 5 by the low-speed high-torque permanent magnet motor 1 is realized through the above connection method. By rationally designing the torsional vibration forced stability controller of the wind turbine pitch system directly driven by the low-speed high-torque permanent magnet motor, the safe and reliable application of the low-speed high-torque permanent magnet motor 1 in the wind ...
