The pitch motorThe pitch motor in variable pitch control mechanism, can be adjusted separately for each blade. The inner gear ring gear and the paddle wheel is engaged, directly controls the blade pitch angle. Displacement sensor to collect the blade pitch angle changes and the formation of PID motor closed-loop negative feedback control.

The motor has the advantages of high efficiency, low temperature rise, low noise, the advantages of long service life, safety and reliability etc.. in variable pitch control mechanism, can be adjusted separately for each blade. The inner gear ring gear and the paddle wheel is engaged, directly controls the blade pitch angle. Displacement sensor to collect the blade pitch angle changes and the formation of PID motor closed-loop negative feedback control.
