Abstract
The utility model relates to a neodymium-ferroboron permanent magnetic motor rotor used for a wind power generator, which comprises a rotary body, neodymium-ferroboron magnetic poles which are arranged on the rotary body and isolating layers, wherein the isolating layer is arranged between adjacent two neodymium-ferroboron magnetic poles. The utility model is characterized in that the utility model also comprises central through holes, fixing holes, fixing screws, adhesive glue and protective layers, wherein the central through holes are positioned on the central position of each neodymium-ferroboron magnetic pole, the fixing holes which correspond to the central through holes of the neodymium-ferroboron magnetic poles are positioned on the rotary body, the fixing screws and the adhesive glue are arranged in the central through holes and the fixing holes, and the protective layers are wrapped on the outer surfaces of the magnetic poles and the isolating layers. Because a double fixing structure is between the magnetic pole and the rotary body, therefore the fastness degree is good, the magnetic leakage is small, the through holes and the fixing holes can be sheathed with drilling holes, the processing is easy, and the precision is high. The protective layers can be used for preventing the oxidation of magnets.
Description
Technical field
The utility model relates to a kind of rotor that is used on the generator, particularly relates to a kind of Nd-Fe-B permanent-magnet motor rotor that is used on the wind-driven generator.
Background technology
Formerly in the technology, be fixed on the turning of rotor for ndfeb magnetic pole, the technology of generally taking is to be carved with stern notch on ndfeb magnetic pole, on turning, be carved with ndfeb magnetic pole on the corresponding dovetail groove of stern notch, in stern notch and dovetail groove, put fixing glue and ndfeb magnetic pole be fixed on turn.The structure that this simple splicing is fixing, firmness is not strong, and leakage field is bigger, even can loss of excitation.To the processing request precision height of rotor, labor content is bigger simultaneously.Because the matter of Nd-Fe-Bo permanent magnet material itself is more crisp, as easy as rolling off a log again oxidation is so processing request is than higher.Again because the magnetic of neodymium iron boron is more intense, therefore, install and fix when bonding at magnetic pole, difficulty is bigger.
Summary of the invention
The purpose of this utility model be for overcome ndfeb magnetic pole in the above-mentioned technology formerly and turn between glued joint the defective that fixing structure is brought merely; provide a kind of processing ratio to be easier to; magnetic pole with turn between combine firmly, have the Nd-Fe-B permanent-magnet motor rotor on the wind-driven generator of being used for of protective layer.
Nd-Fe-B permanent-magnet motor rotor of the present utility model comprises: turn; place ndfeb magnetic pole on turning to place separator between adjacent two ndfeb magnetic poles; be positioned at the central through hole on each ndfeb magnetic pole center; being positioned at has and the corresponding fixing hole of ndfeb magnetic pole central through hole on turning; place the ndfeb magnetic pole central through hole to go up hold-down screw and bonded adhesives in the fixing hole, and be wrapped in the protective layer on ndfeb magnetic pole and the separator outer surface with turn corresponding with it.
Nd-Fe-B permanent-magnet motor rotor remarkable benefit of the present utility model.
● in the rotor of the present utility model, by hold-down screw and bonded adhesives with ndfeb magnetic pole be fixed on turn on.The structure of this double fixed of the utility model, obviously to glued joint fixing sound construction good than simple in the technology formerly, and overcome the big defective of leakage field.
● in the rotor of the present utility model, on turning with ndfeb magnetic pole on the corresponding fixing hole of central through hole can two borehole jacks boring, i.e. two hole time processing moulding.Therefore handling ease and precision height.
● in the rotor of the present utility model, wrap in matcoveredn on magnetic pole and the separator outer surface, it is not oxidized that magnet is enclosed in the protective layer, also strengthened the integrally-built intensity of rotor simultaneously greatly.
