Description
Technical field
The present invention relates to a kind of TRT, the high brushless AC generator of generating efficiency is especially arranged.
Background technology
At present known have CN1313669A with the present invention near patent, and it is made up of the rotor of a cover excitation unit, a cover magnetic conduction device, stator etc.When this brushless AC generator rotor rotates, the magnetic flux size can be changed, flow direction can not be changed.On stator core, there is big or small alternating flux to flow through, do not have that forward and reverse alternating flux flows through, armature can only induce Pulse Electric.During the generator belt load, can produce armature field and have an effect, can reduce rotor speed and generating efficiency with the rotor of processing with permeability magnetic material.
Summary of the invention
Can only send Pulse Electric in order to overcome above-mentioned brushless AC generator existence, armature field can reduce the deficiency of rotor speed and generating efficiency, and the object of the invention provides a kind of generating efficiency high brushless AC generator.
The present invention's technical scheme that is adopted of dealing with problems is: it mainly is made up of shell, stator, field core, rotating cylinder, bearing, base; Rotating cylinder comprises cylindrical shell, end plate, magnetic conduction iron, gear, and field core comprises axle, A, B iron core, forward and reverse line bag, wherein at stator inner hole field core is housed; Connect A iron core and B iron core on the axle; On A iron core and B iron core, respectively be provided with the mutual magnetic pole side by side of a row, magnetic pole is connected with forward and reverse line bag respectively, and magnetic pole of the stator is corresponding with the position of field core magnetic pole; Between stator and field core, cylindrical shell two ends that are made of plastics are housed and are connected end plate; On barrel wall, be provided with the magnetic conduction iron of two misarrangement positions, the rotating cylinder that gear and end plate connect to form is connected with axle, and two to arrange the position of magnetic poles corresponding on the magnetic conduction iron of two misarrangement positions and the field core on the rotating cylinder.When gear imports power into; Connect the field core direct current, during the rotating cylinder rotation, the magnetic conduction iron of two misarrangement positions is alternately connected the jail with field core two row's magnetic poles respectively on the rotating cylinder; Switch forward and reverse magnetic flux; The magnetic conduction sheet iron strip and is imported forward and reverse magnetic flux rotation into, flows through alternating flux on the stator core, and stator line bag induces unsteady flow because of cutting magnetic line.The rotating cylinder of this generator adopts plastic material to process because of required rotary power in light weight is just little, and armature field and plastics rotating cylinder can not had an effect, and is very little to rotating cylinder rotating speed and generating efficiency reduction, so can reach the present invention the high purpose of generating efficiency arranged.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 Fig. 2 is the mutual vertical section structure figure of embodiment of the invention A-A, B-B.
Among the figure 1, shell 2, stator 3, rotating cylinder 3-1, cylindrical shell 3-2, magnetic conduction iron 3-3, end plate 3-4, gear 4, field core 4-1, axle 4-2, A iron core 4-3 positive line bag 4-4, reverse line bag 4-5, B iron core 5, bearing 6, base
Embodiment
In Fig. 1, the embodiment shown in 2, in shell 1, connect the iron core and the line bag of stator 2.Field core 4 is contained on the 4-1 by cylindrical A, B two iron core 4-2,4-5 side by side; On A, B iron core 4-2,4-5 cylindrical, respectively establish row's magnetic pole; Two magnetic poles side by side; Being configured to two magnetic poles is one group, on row's magnetic pole of A iron core 4-2, connects positive line bag 4-3, on the row of one on B iron core 4-5 magnetic pole, connects reverse line bag 4-4 and forms.Cylindrical shell 3-1 two ends that rotating cylinder 3 is made of plastics connect end plate 3-3, on cylindrical shell 3-1 wall, connect the magnetic conduction iron 3-2 of equidistant two misarrangement positions, and gear 3-4 is connected on the end plate and forms.Two to arrange pole dimension identical with quantity on the size of two row's magnetic conduction iron 3-2 and quantity and the field core 4 on the rotating cylinder 3.Rotating cylinder 3 is enclosed within field core 4 outer and axle 4-1 flexible connections, the endoporus of the stator 2 of packing into together.Axle 4-1 is connected with bearing 5, and shell 1 is connected with base 6 with bearing 5.After the assembling, every group of two magnetic poles are corresponding with stator 2 position of magnetic poles on the field core 4, on the rotating cylinder 3 on two misarrangement position magnetic conduction iron 3-2 and the field core 4 position of two row's magnetic poles corresponding.This generator alternately switches A, the forward and reverse magnetic flux of B iron core when leaning on rotating cylinder 3 rotations, the magnetic conduction iron 3-2 on the rotating cylinder 3 imports forward and reverse magnetic flux rotation through air gap from the forward and reverse magnetic pole of field core 4 two rows, and stator line bag induces alternating current because of cutting magnetic line.This rotating cylinder 3 is in light weight, the little armature field of required rotary power influence plastics rotating cylinder rotating speed and luminous efficiency less, so can improve generating efficiency.
