Abstract
The utility model relates to a high efficiency generator, belonging to the technical field of generators. The structure of the existing generators primarily comprises a rotor and a stator, and the output power does not get the optimum state. The utility model designs a high efficiency generator comprising an outer stator, a middle rotor and an inner stator, two faces of the rotor part form two magnetic fields, and in the condition of no change in other conditions, the output power of the generator can be improved. In the manufacture of generators assured to output the same power, the utility model has the advantages of low cost and light weight.
Description
The utility model belongs to technical field of generators.
Its structure of the generator that uses in prior art mainly is made up of parts such as a rotor and stator, brushes.Though the generator of this structure is updated through people, it is still used till today on primary structure.The power generation process of this generator mainly is to utilize rotor excitation coil to make stator produce induced electromotive force in the magnetic field that is produced near stator one side.According to the condition of existing annular magnet magnetic induction, the magnetic induction of two faces exists simultaneously.The generator of present this structure has just utilized the magnetic force face in the rotor outside, internal rotor can not separated the magnetic field of deviating from and be made full use of, so this generator can only produce the power output of a face, does not reach optimum state as yet.Improve the power output of generator, available approach has, and as increasing rotating speed, coil turn etc., output of a generator is continued to increase, but this has certain limit, and this increase also just the machine volume on same structure strengthen and weight increases the weight of.
The objective of the invention is above-mentioned generator is only utilized the shortcoming of rotor outside magnetic force face, a kind of hollow rotor that magnetic field, the outside in the rotor is all made full use of, the generator of two stators are provided.
Invention of the present utility model is to think that according to data the trench bottom of winding also exists the comparatively dense magnetic line of force, that is to say to exist stronger magnetic field, also proves this point by experiment.Being based on the recognition, can be hollow body by the past solid transformation of the way with general generator amature, promptly becomes a sleeve rotor.Reinstall a stator in sleeve rotor the inside, just formed the high efficiency generator of a hollow rotor, two stators.Stator can be divided into external stator and internal stator.External stator is identical with existing stator structure of generator, and internal stator is to be contained in the hollow rotor, and guarantee that its electrical property is consistent with external stator, for guaranteeing that internal stator does not produce axially or moves radially, be with behind the adapted bearing between the hollow rotor shafts, can adopt fixedly internal stator axle of an end support, guarantee that rotor radially freely rotates.
Magnetic surface and internal stator that the advantage of this generator has been to make full use of hollow rotor inboard form new magnetic field, and just there are two identical polar induced electromotive forces in this like this generator, thereby can improve the power output of unit.When making the generator of equal-wattage, can reduce cost weight saving.
Generator of the present utility model is done following further specifying in conjunction with the accompanying drawings:
Accompanying drawing be generator semi-section schematic diagram,
1 is the fixed mount of internal stator axle 9, is used for fixing an end of internal stator axle 9.Be equipped with unshakable in one's determination 8 and the winding 7 and bearing 11 of inner and outer ring is housed at two ends on the internal stator axle 9.Rotor axle 5 is for having winding 6 on hollow body, the axle 5, and winding 6 can be contained in the inboard of rotor axle 5, also can be contained in the outside of rotor axle 5.Winding 6 among Fig. 1 is contained in the inboard, and the winding 6 among Fig. 2 is contained in the outside.Rotor axle 5 is that four outside leaning in the axle two ends have 10,11 supportings of inner and outer ring bearing to be fixed on middle.3 is that external stator iron core, 4 is the external stator winding, and 2 is electric machine casing.
Claims (2)
1, a kind of high efficiency generator that constitutes by rotor, stator etc., it is characterized in that the external stator formed by external stator iron core [3], external stator winding [4], the rotor formed by rotor axle [5], winding [6], by internal stator winding [7], internal stator iron core [8], internal stator axle [9] form internal stator constituted.
