Description

The integrated electric generator

One, technical field:

The utility model relates to a kind of integrated electric generator.

Two, background technology:

At present, has only an armature in the known electric machine structure, and in fact, each main pole of dc permanent magnet motor all has two heteroplasia magnetic fields, and be regardless of positive and negative, so traditional permanent magnet direct current motor has only utilized the heteroplasia magnetic field of one of them face, the magnetic field energy that the heteroplasia magnetic field of another face is provided does not obtain utilizing.

Three, summary of the invention:

The purpose of this utility model is for overcoming above-mentioned deficiency of the prior art, and a kind of integrated electric generator of heteroplasia magnetic field of two faces that can make full use of main pole is provided.

The purpose of this utility model is realized by following mode:

The utility model comprises hood shell, end cap, stator, rotor, motor shaft, commutator, Elastic Sliding copper sheet, electricity ring, it is characterized in that stator adopts and the concentric double-deck armature of motor shaft, internal layer is an armature axis, be located on the motor shaft, skin is the annulate shaft armature, leaves the gap between two-layer armature, rotor is the tubular pole ring that is inlaid with permanent magnet pole, rotor is located in the gap of double-deck armature, and leaves air gap between armature and magnetic pole, is provided with bearing between end cap and motor shaft.

The utility model has the advantages that: made full use of the heteroplasia magnetic field of two faces of main pole, when itself makes motor operation, can export electric energy again, with utilizing, can also have been produced generator or motor separately by other power consumption equipment.

Four, description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of rotor.

Five, embodiment:

The utility model can have two kinds of concrete execution modes, and a kind of is the shell output form, and another kind is the axle output form.At first, with the shell output form is example, the utility model is described: with reference to accompanying drawing, the utility model comprises hood shell 10, end cap 12, stator, rotor, motor shaft 1, commutator 15, Elastic Sliding copper sheet 12, electricity ring 13, the double-deck armature that stator adopts and motor shaft 1 is concentric, the iron core of armature is repeatedly pressed by silicon steel sheet and is formed, internal layer is an armature axis 2, being cylindric is connected with motor shaft 1 by key or flower tooth 16, motor shaft 1 is a hollow shaft, outer armature is an annulate shaft armature 3, annulate shaft armature 3 is connected with the solid frame 4 usefulness screws of the armature of a laminated structure that is located at the one side, concentric to guarantee annulate shaft armature 3 and motor shaft 1, simultaneously, also make and leave certain clearance between two-layer armature, rotor is made up of permanent magnet 6 and tubular pole ring 7, permanent magnet 6 adopts rare-earth permanent magnet, can be made into the square or watt shape of prolate, both sides are semicircle, permanent magnet 6 is at least a pair of as required, form by center of circle symmetry is arranged on the tubular pole ring 7 in couples, tubular pole ring 7 usefulness permeability magnetic materials are made, on tubular pole ring 7, mill out both sides and have semicircular opening groove according to the shape of permanent magnet 6 and quantity, permanent magnet 6 is embedded in the groove, the end face of the end face of permanent magnet 6 and pole ring 7 maintains an equal level, and tight with screw and riveting again, rotor can be a cover, two covers about also can making, the outside of rotor and end cap 12 usefulness screws are fastening, and the inboard extend in the gap of double-deck armature, and leaves air gap between two-layer armature and rotor.Core motor axle 1 rolls by bearing 14 and end cap 11 and cooperates, commutator 15 can adopt brushless electronic commutator, what select for use in the utility model is the commutator of common mechanical structure, be to make by the wedge shape copper sheet, be contained in a side of stator, cooperate with motor shaft 1, the termination of armature axis 2 windings is welded on the afterbody of commutator 15, and brush 8 is contained on the brush carrier 9, brush carrier 9 is fixed on the end cap 11, electricity ring 13 cooperates with motor shaft 1, and Elastic Sliding copper sheet 12 has two, is fixed on the end cap 11, encircle 13 Elastic Contact with electricity, and be connected with brush 8 usefulness leads, the input and output lead of motor penetrates from core motor axle 1, is connected with electricity ring 13.If the utility model is made the form of axle output, only need on the outside of rotor motor shaft 1, to establish a rotor link, by link rotor is connected with motor shaft 1, remove the solid frame 4 of armature simultaneously, and the bar 5 usefulness screws of establishing on the annulate shaft armature 3 are connected with hood shell 10, be about to annulate shaft armature 3 and be fixed together, cooperate by bearing element between armature axis 2 and the motor shaft 1 with hood shell 10.

Enter into electricity ring 13 as electric current by lead, after Elastic Sliding copper sheet 12, brush 8, commutator 15 are input in the winding of armature axis 2, the action of a magnetic field of armature axis 2 and rotor produces torque, rotor rotates, the magnetic line of force of the external magnetic field of inlaying lead perpendicular cuts rotor in the annulate shaft armature 3 and produce electromotive force, the closed-loop path that this electromotive force forms can be directly used in illumination, also can be stored in the storage battery standby through charging circuit.The utility model also can be connected to external power on the annulate shaft armature 3, and armature axis 2 has reached the purpose of energy-efficient province material as generating.The utility model can also be by changing armature axis 2 and annulate shaft armature 3 winding offline mode and with the connected mode of external power, be made into single motor or generator.
