Problems solved by technology

Because the LED light-emitting tube on the instrument can only provide a small excitation current for the motor, and the small magnetic field generated by the small excitation current cannot make the generator generate electricity quickly at a low speed, and it cannot meet the needs of the car in the electric motor. Idle speed can also make the generator generate electricity, which cannot meet the current national requirements for energy saving and emission reduction in the automobile industry.
[0006] 2) poor adaptability
With the development of new engineering vehicles, engineering vehicles require the generator to work without connecting the indicator light and the ignition switch. However, the low-cost single-function regulators commonly used at present do not have this function, and an external indicator light or The ignition switch provides excitation current to the generator to make it generate electricity

Description

technical field [0001] The invention relates to an automobile voltage regulator, in particular to a novel self-excitation single-function automobile voltage regulator. Background technique [0002] The electrical system on the car is mainly powered by the car generator, and the regulator is the core component that controls whether the generator is generating power or not, and is an indispensable and important part of the car power generation system. [0003] At present, the existing single-function series regulators all need to rely on the indicator light connected to the battery to provide a large excitation current through the rotor coil of the motor to generate a magnetic field, and the stator rotates to cut the magnetic field to generate current, thereby enabling the generator to generate electricity. The function terminals of the single-function series regulator are generally four terminals B+, D+, F, E or three terminals D+, F, E. Such a regulator is mainly composed of...
