Abstract

The utility model discloses an off-grid iron-coreless wind power generator, which comprises a stator and a rotor. The stator comprises a round box and several iron-less coil windings fixed in the round box by non-magnetic materials. The coil windings are distributed windings or concentrated windings; the rotors are permanent disks coaxially arranged on both sides of the stator, and a space is reserved between each rotor and the stator. The relative rotation between the stator and the rotor may be that the stator is fixed and the rotors on both sides rotate synchronously, or that the rotors on both sides are fixed and the stator rotates. The coil windings are connected in different ways to realize two-phase, three-phase or multi-phase output, and the output is direct current or alternating current. The utility model adopts the stator structure without iron core, which has small internal resistance, reduces the torque force of the load, and also eliminates the huge electromagnetic attraction between the stator and the rotor (eliminates the cogging torque and core loss in the traditional structure) , reducing the volume and weight of the generator, and improving the efficiency of the generator.

Description

There is not the iron core wind-driven generator from the net type

Technical field

The utility model relates to generator, and being specially does not a kind ofly have the iron core wind-driven generator from the net type.

Technical background

Now use in the technology, the generator of wind power generation normally has permanent magnet direct-driving aerogenerator unshakable in one's determination, though this generator is simple in structure, reliable operation, the huge electromagnetic attraction that produces between stator and the rotor make electric machine structure complexity, cost height, difficulty is installed; Also because this generator have cogging torque and certain core loss, these drawbacks limit further developing of wind power generation industry.

The utility model content

The purpose of this utility model provided a kind of eliminate the electromagnetic attraction between the stator rotor, no teeth groove torque and core loss, raising power of motor do not have the iron core wind-driven generator from the net type.

That can realize above-mentioned purpose does not have the iron core wind-driven generator from the net type, comprise stator and rotor, different is, and described stator comprises with non-magnet material is fixed in several iron-less core coil windings that winding supports, and described coil windings is distributed winding or centralized winding; Described rotor keeps the interval with thermolysis for the permanent magnetism dish that is located in the stator both sides between each rotor and the stator.

The stator that relatively rotates in the middle of can being of described stator and rotor is fixed, and the rotor of both sides rotates synchronously.

Also can be that the both sides rotor is fixed, middle stator rotates.

Described winding is supported for round box.

Described round box is divided into the fan-shaped lattice of five equilibrium, and described fan-shaped lattice are the fixed position of each coil windings in the circle box.

Be spaced apart 1mm～5mm between described rotor and the stator, can determine the concrete size of space according to the generator of different size.

Take dissimilar connected modes between described each coil windings, can realize two phase electricity, three-phase electricity or the heterogeneous electricity output of generator, describedly be output as direct current or interchange.

Advantage of the present utility model:

1, the utility model does not have the stator of iron core wind-driven generator by adopting the iron-less core coil winding construction from the net type, internal resistance is little, alleviated the torque power that produces load, also eliminated simultaneously huge electromagnetic attraction between stator, the rotor, cogging torque and core loss in the traditional structure have been eliminated, dwindled generator volume, reduced generator weight, improved generator power.

2, the utility model is easy for installation, safeguards that simply noise is little, and cost descends.

3, the utility model is a desirable type of high-power permanent magnet direct wind-driven generator, can utilize the various power development energy in all parts of the world efficiently.

Embodiment

The utility model does not have the iron core wind-driven generator from the net type and is made of rotor 1 and stator 4, described stator 4 comprises the plastics circle box 2 and several iron-less core coil windings that are arranged in the round box 2 of one-step die casting, coil windings is distributed winding or centralized winding, the fan-shaped lattice 3 that are provided with around branches such as axis holes in the circle box 2 are divided, coil windings of coupling in each fan-shaped lattice 3, and fix with non-magnet material, as shown in Figure 1 and Figure 2.

The both sides of stator 4 equidistantly respectively are provided with a rotor 1, and this rotor 1 is the permanent magnetism dish, and two rotor 1 is coaxial with middle stator 4 threes and diameter is identical, rotor 1 and stator 4 interval 1mm～5mm; Relatively rotating between rotor 1 and the stator 4 can be that stator 4 is fixing, and the rotor 1 of both sides rotates synchronously, also can be that both sides rotor 1 is fixing, and stator 4 rotates, and the stator 4 of the rotor 1 of rotation or rotation is by fans drive, as shown in Figure 1.

The utility model does not have the iron core wind-driven generator from the net type two phase electricity of direct current or interchange, three-phase electricity or heterogeneous electricity output is arranged, and can be achieved by the dissimilar connected modes between each coil windings.
