Description

The self-excitation surper-low-speed generator

The utility model relates to the internal combustion engine Blast Furnace Top Gas Recovery Turbine Unit (TRT), is specifically related to the generator of motor vehicles such as automobile, tractor, tricycle.

The motor vehicle generator of prior art is mainly regulated parts by housing, rotor, stator and rectification and is constituted.It exists not enough: the one, in the field circuit that constitutes by rotor and stator, the magnetic circuit gap is too much, the magnetic flux leakage that air resistance magnetic causes is big, usually exciting current often causes the generator working temperature too high, generally above 150 ℃ greater than more than the 7A, the lubricating oil of bearing is overflowed, accelerated the wearing and tearing of bearing, reduced useful life, general useful life, less than was 1 year.The 2nd, the magnetic field magnetic conductive area is little, under 1000 rev/mins situation, zero current only occurs, under 2500 rev/mins～3500 rev/mins conditions, can work usually, and the raising of generator speed, the wearing and tearing of having accelerated carbon brush need often to change.

The purpose of this utility model is to provide a kind of minimizing magnetic circuit gap and exciting current, increases magnetic conductive area, still can generate electricity and improve the self-excitation surper-low-speed generator in useful life under slow-speed of revolution condition.

The technical solution of the utility model is achieved in that this self-excitation surper-low-speed generator mainly by forward and backward housing, and rotor, stator and rectification are regulated parts and constituted; Its improvements are: the big outer rounded ends of magnetic guiding loop is fixed on the back casing, on its other end and the end face that little cylindrical is connected, is provided with the spill annular groove; The little cylindrical of magnetic guiding loop is provided with coil.Be connected pawl utmost point iron core in the rotating shaft, its big cylindrical inner chamber swivel becket is enclosed within on the coil cylindrical of magnetic guiding loop, and its iron core rotates and inserts in the hollow form inner chamber of the little cylindrical of magnetic guiding loop.The front end of pawl utmost point iron core cylindrical rotates in the spill annular groove of inserting on the big cylindrical end face of magnetic guiding loop.

When implementing technique scheme, the coil of selecting stator core usually is a kind of of individual layer wave winding structure or double-deck wave winding structure; Adjuster is connected in the back casing inner chamber, and joins with the rectifier bridge circuit.

Because the utility model adopts above-mentioned magnetic guiding loop structure, the magnetic flux leakage that has reduced the generation of magnetic circuit gap and air resistance magnetic is big, and exciting current is less than 3A; The magnetic field magnetic conductive area increases, and under 1000 rev/mins condition, still can satisfy the needs of vehicular electrical appliance electricity consumption after tested, and generator is worked under the slow-speed of revolution, improves 1.5 times than original generator for electricity generation efficient, has reduced the wearing and tearing of parts, has prolonged its useful life.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
