Abstract
The utility model relates to a rotor windingless AC and DC brushless generator. The shaft is provided with a magnetic conducting rotor; the middle in the magnetic conducting external sleeve on the stator is fixedly provided with winding exciting coils in a circumferential direction; the two ends are provided with an armature iron core of a silicon chip which is provided with a tooth-shaped cross section, or one end is replaced with a magnetic conducting cover; the tooth is wound with output coils, and the cross section of the rotor also forms a tooth shape. The rotor windingless AC and DC brushless generator which is not the 50Hz model and resists pollution has the obvious advantages of small size, simple structure, long service life, large power generating capacity and low cost. The 50Hz- model has the advantage of burning resistance and long service life. The rotor windingless AC and DC brushless generator is particularly suitable for the charge and illumination of a motor vehicle and a motor ship, the electricity consumption of electric appliances, and AC electric welders.
Description
The utility model belongs to the induction generator technical field.
Generator in the past generally all has brush, and rotor has winding, and its complex structure, cost height, motor easy burn-out, useful life lack; Also have brushless, it is made up of 12 parts such as armature spindle, rotor core, the fore paw utmost point, the rear solid end utmost point, magnet exciting coil work durm frame, magnet exciting coil insulating frame, magnet exciting coils, though save brush, part increases complex structure in addition, be difficult for making, exciting power is big, the temperature rise of excitation wire group, easy burn-out, life-span is short, and should not work in the environment of severe contamination if any silt.China Patent No. 90206166.9, the rotor of inventing for the inventor does not have the winding alternating current generator, it has magnetic conduction rotor, cooling fan and the drive pulley that is fixed on the axle, and there are two groups of silicon chip armature cores at the stator two ends, and there is magnet exciting coil the centre, magnet exciting coil axially twines in the vat of armature core, for the generator of non-50HZ type, though its volume is less, structure is simpler, but its energy output is less, and generating efficiency is lower.
The purpose of this utility model provides a kind of novel rotor does not have the winding brushless generator, and its energy output is bigger, and generating efficiency is higher, and cost is lower, and useful life is longer.
The utility model is achieved in that a kind of rotor does not have the winding brushless generator, comprise rotating shaft, be fixed on the magnetic conduction rotor in the rotating shaft, cooling fan and drive pulley, it is characterized in that magnetic conductive jacket is arranged on the stator, near two ends, magnetic conduction skin the inside, respectively be fixed with the silicon chip armature core, the axle cross section of silicon chip armature core is a profile of tooth, be wound with output winding on the tooth, two iron cores together around or respectively around, single-phase, two-phase or three-phase, can be respectively with a tooth, bidentate, three teeth etc. are one group of coiling, and output winding coiling and wiring are by single-phase, two-phase or three-phase connection are the same with the connection of existing common generator.The cross section of rotor and armature core mating part also is a profile of tooth, and the coiling number of phases can be different, and this tooth is all corresponding with the tooth group on the silicon chip armature core of coiling, or corresponding with the tooth of coiling not.Between above-mentioned two armature cores, be fixed with the excitation winding pole coil that twines by axle garden Zhou Fangxiang in the inside of magnetic conductive jacket.The armature core of an above-mentioned wherein end also available loop magnetic conductive cover replaces.Above-mentioned excitation winding pole coil preferably is wrapped in and twines on the frame, twines frame and can be fixed on magnetic conductive jacket or the magnetic conductive cover.Permeability magnetic material can adopt low C steel, as below No. 35 or the mild steel below No. 25 make.Electric current is directly exported, and is alternating current, as through rectification, is direct current, and rectifying device can be installed on the end cap.But necessarily require to provide under the situation of 50HZ alternating current at electrical appliance, the alternating current generator that is exclusively used in motor vehicles can not be exported 50HZ AC power frequency electric current, must otherwise designed be exclusively used in the generator of this type of 50HZ.
Effect of the present utility model is tangible, for non-50HZ generator, it except have volume little, simple in structure, be not afraid of the characteristics such as burning, life-span influence (not being afraid of sandy soil), voltage long, that be not subjected to environmental pollution is stable, have also that energy output is big, generating efficiency is higher, lower-cost remarkable advantage.For the industrial frequency AC generator of 50HZ, the common generator of the volume ratio of this generator is big slightly, but from durable, be not afraid of pollutions, be not afraid of burning, aspect such as the life-span is grown, be far superior to common generator.Be specially adapted to occasions such as charging on motor vehicle, the power-driven vessel, illumination, electrical equipment electricity consumption and A.C. welder.
Elaborate below in conjunction with embodiment.
Fig. 1 is that the structure master of embodiment 1 looks schematic diagram;
Fig. 2 is an A-A profile among Fig. 1;
Fig. 3 is that the structure master of embodiment 2 looks schematic diagram.
Among the figure, 1 is rotating shaft, and 2 is the magnetic conduction rotor, and 3 is the silicon chip armature core, 4 is output winding, and by single-phase, two-phase or three-phase connection wiring (Fig. 2 is single-phase connection wiring), 5 is magnetic conductive jacket, 6 is magnet exciting coil, and 7 is the magnet exciting coil framework, is fixed on the magnetic conductive cover 8,9 is that front end housing and magnetic conductive jacket 5 fix, and 10 is fan, 11 is drive pulley, and 12 is that rear end cap and magnetic conductive jacket 5 fix, 13 is bearing, and 14 is rectifying device, and 15 is heat dissipation wind channel (also can not have).Whole stator is contained on the support.
The technical parameter of the utility model embodiment is referring to table 1.
