More Information
Summary:The utility model relates to an automatic speed and illumination controller for a small tractor, belonging to the vehicle illumination equipment. The utility model is used for the automatic conversion of illuminating filaments when the small tractor runs in the high and low speed. The controller comprises a three-phase permanent magnetic AC generator, a three-phase bridge type full-wave rectifying circuit, a voltage distributing and comparing circuit, a switch amplifying circuit and an illuminating converting circuit, the three-phase output of the generator are rectified and transferred the power supply to the high voltage filament and the low voltage filament, and the control circuits are used to realize the automatic conversion of the illumination. The utility model provides four control circuit instances the relay control, the contactless switch control, the use of the operational amplifier circuit and the circuit through regulating the exciting current of the generator to stabilize the output voltage.
