Abstract
The invention discloses an off-grid type coreless wind driven generator, comprising stators and rotors, wherein each stator comprises a circular boxe and a plurality of coreless coil windings which are fixed in the circular boxes by a non-magnetic material, and the coil windings are distributed windings or centralized windings; the rotors are permanent magnetic discs concentrically arranged on both sides of the stators, and gaps are retained between each rotor and each stator. The relative rotation between the stators and the rotors can be the situation that the stators are fixed and the rotors on both sides rotate simultaneously, or the situation that the rotors on both sides are fixed and the stators rotate. Different connection ways are adopted among the coil windings to achieve two-phase electricity output, three-phase electricity output or multiple-phase electricity output, and the output electricity is direct current or alternating current. In the invention, since the structure of the coreless stators is adopted, internal resistance is small, the torsion moment of load is alleviated, meanwhile, huge electromagnetic attraction between the stators and the rotors is also eliminated, (cogging torque and core loss in a traditional structure are eliminated,) the volume and the weight of the turbine are reduced, and the power of the turbine is increased.
Description
(1) technical field
The present invention relates to generator, being specially does not a kind ofly have the iron core wind-driven generator from the net type.
(2) 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.
(3) summary of the invention
The purpose of this invention is to provide 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 that described stator comprises that winding supports and several iron-less core coil windings, each coil windings is fixed in winding with non-magnet material and supports, and each coil windings is distributed winding or centralized winding; Described rotor is the permanent magnetism dish, and the stator both sides are coaxial respectively to be provided with a rotor, keeps the interval that produces air gap and have thermolysis 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 the two phase electricity of generator, three electricity or multinomial electricity output, describedly be output as direct current or interchange.
Advantage of the present invention:
1, the present invention 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 present invention is easy for installation, safeguards that simply noise is little, and cost descends.
3, the present invention 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.
