3,044,195 generator speed control board governor since the output voltage of the generator speed control board S6700H U = Cnφ manufacturers, for a generator for generating speed control board S6700H, c is a constant. In operation, the rotation speed n is changing the supply speed control board S6700H, make the generator terminal voltage is kept constant, by varying the magnetic flux φ can be adjusted in size, while the size of the magnetic flux change is determined by the excitation current a. Thus, when the generator rotational speed n increases S6700H, the right to use the field current can be reduced to reduce the magnetic flux to maintain the output voltage of the generator constant; Conversely, when the generator speed is reduced, increasing the field current, silicon rectifier power motor speed controller so that the role of the voltage regulator when the generator rotational speed change, automatically change the size of the excitation current. S6700H-2 speed control board has a hydraulic governor feedback mechanism of its rigid structure and above without feedback hydraulic governor is basically the same, only the upper end of the lever righteousness AC A governor is not installed (Figure 2) in a fixed hinge but connected with the servo piston rod. This change allows the sensing element, hydraulic components and fuel adjustment amplifying the relationship between the institution following changes occur.
