Abstract
The utility model relates to an automobile brushless generator, which is characterized in that a rotor shaft of the generator is equipped with two groups of magnetic yokes and claw poles, wherein the front end cover and the rear end cover are respectively fixed with a stator iron core, the stator iron cores are respectively fixed with excitation coils, the two groups of excitation coils are parallelly arranged and are arranged on a same shaft after being parallelly connected, thereby being capable of increasing the output power of the generator. The automobile brushless generator has no carbon brush and spark, has low radio electric wave interference, simple structure, low maintenance workload and long service life, and is suitable for various large automobiles.
Description
Technical field
The utility model relates to the automobile current generator field, particularly a kind of automotive brushless generator.
Background technology
At present, known automobile current generator is general to divide two kinds, a kind of is that the brush generator is arranged, another kind is a brushless generator, the brush generator is arranged because its useful life is short, and maintenance is inconvenient, also withdrawing from the market gradually, as everyone knows, the length of current value that generator produced and armature, cross section is directly proportional, so want to increase power output, must finish by the number of turn that increases coil, but along with the increase of coil turn, other parts of generator are also enlarging thereupon, and the volume of generator is increasing like this, install inconvenient, and maintenance is extremely inconvenient, and when especially magnet exciting coil broke down, maintenance cost was high.
Summary of the invention
Provide a kind of automotive brushless generator in order to overcome above-mentioned not enough the utility model, it not only can export more high-power, and comparatively speaking under the less situation of generator volume, can also reduce maintenance cost, also is very easy to find eliminating when magnet exciting coil has fault.
The utility model solves technical scheme that its technical problem adopts: two groups of yokes are installed on the armature spindle of generator, the pawl utmost point, difference fixed rotor iron core on front and rear cover, on rotor core, distinguish the fixed excitation coil again respectively, described two groups of magnet exciting coils be arranged in parallel, and the coaxial installation in back in parallel, be arranged in parallel because two groups of pawl utmost points and magnet exciting coil are folded so mutually, so the magnetic potential and the magnetic flux that produce increase accordingly, and the air gap unit magnetic flux of armature is constant, thereby reached the purpose that improves output of a generator, moreover magnet exciting coil divides two groups of settings, easier detection eliminating when fault is arranged.
The beneficial effects of the utility model are: improve the power output of generator more, non-carbonate, no-spark, radiobeam disturb little, simple in structure, and maintenance workload is little, and long service life is applicable to each full-sized car.
