Abstract

The utility model belongs to the technical field of generators, in particular a permanent magnet three-phase disc type generator. Permanent magnets are respectively and fixedly arranged on inner walls of an upper housing and a lower housing, plastic packaging is carried out on an armature winding formed by connecting three groups of coils in series for forming a disc which is further connected with a shaft into a whole by plastic packaging, a three-phase lead wire of the armature winding is led out through a shaft hole, the three-phase lead wire is a three-phase armature, the disc is arranged between the permanent magnets arranged on the upper housing and the lower housing, and the shaft fixed on the disc utilizes bearings on the upper housing and the lower housing for support. The permanent magnet three-phase disc type generator has the advantages of small size, light weight, simple structure and reliable and stable performance; a rotor is an outer housing and adopts a full closed structure, thereby being applicable to harsh working environments; a stator does not contain ferromagnetic materials, thereby eliminating the cogging effect and being started rapidly; and the permanent magnet three-phase disc type generator is applicable to wind power, hydraulic power and small power-driven power generation purposes.

Description

Permanent magnetism three-phase disk generator

Technical field:

The utility model belongs to the technical field of generator, refers in particular to a kind of permanent magnetism three-phase disk generator.

Background technology:

Electric energy is one of topmost energy of modern society, and generator is the plant equipment that other forms of energy conversion is become electric energy, and the form of generator is a lot, but its operation principle is all based on the law of electromagnetic induction and electromagnetic force law, general generator adopts slip ring, brush structure, the employing DC generation that has, and DC generator has commutator, complex structure, during manufacturing expenses, price is more expensive, and easy break-down, difficult in maintenance, efficient is low; The cored structure of the employing that has, iron loss is big, and starting has slot effect, starts not rapidly, and big with weight under the constant power, and the not full-closed structure that has can not be worked under adverse circumstances.

Summary of the invention:

The purpose of this utility model provides a kind of simple in structure, dependable performance, stable, the totally enclosed permanent magnetism three-phase disk generator that can work under adverse circumstances.

The utility model is achieved in that permanent magnetism three-phase disk generator, it is characterized in that: on the inwall of upper shell and lower house, be set with permanent magnet respectively, the armature winding plastic packaging that is formed by three groups of coil series connection forms a disk, and with the axle plastic packaging be one, and three phase terminals of armature winding are drawn by axis hole, this three phase terminal is threephase armature, described disk is arranged between the permanent magnet on upper shell and the lower house, is fixed on axle on the disk and utilizes bearings on upper shell and the lower house.

Above-mentioned permanent magnet is an even number, and is arranged on upper shell and equates that with permanent magnet quantity on the lower house polarity is opposite.

Above-mentioned armature winding adopts star connection.

The outstanding compared to existing technology advantage of the utility model is:

1, the utility model axial dimension is little, and is in light weight, simple in structure, dependable performance, stable;

2, the utility model rotor is a shell, adopts full-closed structure, can be fit to bad working environment;

3, stator of the present utility model does not contain ferromagnetic material, has eliminated slot effect, starts fast;

4, the utility model is fit to and wind-force, waterpower and the power-actuated power generation application of petty action.

Fig. 1 is a cross-sectional view of the present utility model;

Fig. 2 is one of perspective view of the present utility model;

Fig. 3 is two of a perspective view of the present utility model;

Fig. 4 is an example structure schematic diagram of the present utility model.

Embodiment:

With specific embodiment the utility model is further described below,

Adopt wind power generation as embodiment, referring to Fig. 1-4:

Permanent magnetism three-phase disk generator 80, on the inwall of upper shell 10 and lower house 40, be set with permanent magnet 20 respectively, armature winding 30 plastic packagings that formed by three groups of coil series connection form a disk 31, and with axle 60 plastic packagings be one, and three phase terminals 301 of armature winding 30,302,303 draw by axis hole, this three phase terminal 301,302,303 are threephase armature, described disk 31 is arranged between the permanent magnet 20 on upper shell 10 and the lower house 40, the axle 60 that is fixed on the disk 31 utilizes the bearing 50 on upper shell 10 and the lower house 40 to support, upper shell 10, the opposite polarity permanent magnet of the corresponding respectively fixedly even number of lower house 40 20 is as rotor, and rotate around axle 60, constitute an outer-rotor structure, stator is to be formed by armature winding 30 and axle 60 plastic packagings.

The novel operation principle of this use is: under the effect of extraneous wind-force to fan blade 70, driving external rotor begins to rotate, permanent magnet begins to rotate, produce the magnetic field of rotation, make the magnetic force body of armature cutting permanent magnet, produce electromotive force,, promptly realized generating by 301,302,303 outputs of three phase terminals.

The utility model axial dimension is little, and is in light weight, simple in structure, reasonable in design, dependable performance, stable, generating efficiency height; Rotor is a shell, adopts full-closed structure, can adapt to bad working environment; Stator does not contain ferromagnetic material, has eliminated slot effect, starts fast; Be fit to and wind-force, waterpower and the power-actuated power generation application of petty action.

The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection range of the present utility model.
