Automobile Exhaust Gas Turbine Driven Tangential Permanent Magnet Generating Device

Abstract

The invention provides an automobile exhaust turbine driving tangential permanent magnetic power generation device, and belongs to the technical field of automotive electrical appliances. The device is composed of an engine, a turbine motor, a permanent magnetic power generation device body, a voltage stabilization controller and a storage battery, a permanent magnetic rotor is of a tangential structure, permanent magnets are sequentially arranged in a radial groove of a pole shoe type rotor iron core in the mode that poles N are opposite and poles S are opposite, the pole shoe type rotor iron core is fixedly arranged on a shaft, a turbine motor shell is fixedly arranged on a rear end cover of a generator through a bolt, and the shaft of the turbine motor and a rotor shaft of the permanent magnetic power generation device body are the same shaft. The structure is compact, occupied space is small, the device is driven by exhaust gas exhausted out of the automobile engine, energy is saved, and cost is lowered.

Description

technical field [0001] The invention provides a tangential permanent magnet power generation device driven by an automobile waste gas turbine, which belongs to the technical field of automobile motors and electrical appliances. Background technique [0002] The automobile industry is a symbol of modern industry and a leading industry in the development of the national economy. It plays an indispensable role in agricultural production, transportation and all aspects of human production and life. At present, the generator used in automobiles is directly driven by the engine, and consumes Larger effective power, the output voltage of the permanent magnet alternator changes with the speed change, the output voltage is low when the speed is low, and the output voltage is high when the speed is high. In order to make the output voltage relatively stable, in the existing technology, Voltage stabilization measures such as mechanical voltage regulation and parallel transistor voltage...

[0002] The automobile industry is a symbol of modern industry and a leading industry in the development of the national economy. It plays an indispensable role in agricultural production, transportation and all aspects of human production and life. At present, the generator used in automobiles is directly driven by the engine, and consumes Larger effective power, the output voltage of the permanent magnet alternator changes with the speed change, the output voltage is low when the speed is low, and the output voltage is high when the speed is high. In order to make the output voltage relatively stable, in the existing technology, Voltage stabilization measures such as mechanical voltage regulation and parallel transistor voltage regulation are adopted, but there are still disadvantages such as low reliability, low specific power, and temperature rise of the generator.
