Abstract
The utility model discloses a high performance rare-earth permanent-magnetic generator which is composed of tile-shaped magnetic steel, rotor magnetic poles and a circular rotating shaft, wherein the tile-shaped magnetic steel provided with a central hole is formed by processing high performance permanent magnetic materials, each of the rotor magnetic poles is formed by splicing one or more rare-earth tile-shaped magnetic steel of identical polarity, and the rare-earth tile-shaped magnetic steel is fixed to the magnetic conduction circular rotating shaft by bolts and adhesive to form a rotor of the rare-earth permanent-magnetic generator. An iron core of a stator is formed by overlapping skewed slot structures; a negative effect on electric appliances, which is caused by radio frequency interference generated by electronic elements in an excitation circuit of a conventional generator can be eliminated the method of magnetic saturation and constant voltage. The generator has the advantages of good performance, high reliability and low failure rate, and is suitable for high-grade electricity supply places, such as armies, post and telecommunications departments, telecommunication departments, banks, hospitals, computer rooms, etc.
Description
The utility model discloses a kind of tile-shaped magnet steel that adopts high-performance rare-earth permanent magnet material to be processed into to have centre bore, rotor magnetic pole is combined into by the rare earth tile-shaped magnet steel of 1～n sheet same polarity, with Luo bolt and adhesive the rare earth tile-shaped magnet steel is fixed in the circular rotating shaft of magnetic conduction to form rare-earth permanent magnet generator rotor.
Skewed slot closed assembly structure is adopted in stator core of the present utility model, can suppress the interference of slot ripples effectively to the generator voltage waveform, the resistance that magnetic pull produces when reducing generator no-load running has solved the big technical barrier of the wasted work of rare earth permanent-magnetic generator reluctance force in the past.
The utility model adopts magnetic saturation constant voltage method can eliminate the harmful effect of the radio frequency interference of the electronic component generation in the conventional generator excitation circuit to electrical appliance, improved the power supply quality of generator, the implementation method of magnetic saturation constant voltage is the saturation that increase and decrease stator and rotor cores length is regulated magnetic circuit.
The utility model adopts the rare-earth rotor excitation, does not have the excitation winding of conventional generator, field coil, the control circuit that electric capacitor and electronic component are formed.Thereby can improve the operational reliability of generator, reduce the failure rate of generator, and it is little to have a load irregularity of wave form, the voltage transient value is good and take advantage of distinguishing features such as year inductive load ability is strong.
Zinc-plated grade for overcoat is adopted on rare earth tile-shaped magnet steel of the present utility model surface, can prevent corrosion, can reduce thermal radiation again, can also prolong the useful life of rare earth magnetic steel, solve rare earth magnetic steel and in motor application, be difficult to the technical barrier of lowering the temperature, thereby opened up a feasible way for the application technology of high-power rare-earth electric motor.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model; Fig. 2, Fig. 3, Fig. 4 are stator structure schematic diagram of the present utility model; Fig. 5, Fig. 6 are rare earth tile-shaped magnet steel structural representation of the present utility model; Fig. 7, Fig. 8 are rare earth magnetic steel rotor structure schematic diagram of the present utility model.Among the figure: 1 is the rare earth tile-shaped magnet steel; 2 is bolt; 3 are rotating shaft; 4 is the stator assembly;
5 is shell.
The rare earth tile-shaped magnet steel [1] of 1～n sheet same polarity is combined into rotor magnetic pole, rare earth tile-shaped magnet steel [1] is fixed in the circular rotating shaft [3] of magnetic conduction, put into stator assembly [4] again with bolt [2].
But the mounting structure reference structure schematic diagram 1 of motor integral body, installation method and conventional products are similar, no longer narration.
In sum, its performance of high-performance rare-earth permanent-magnetic generator is good, the reliability height, and failure rate is low, is particularly suitable for demanding power supply places such as army, post and telecommunications, communication, bank, hospital and computer floor.
