Dc brushless motorsebopeho sea utloahala, lebelo la eona ha e le hantle le tsitsitse haholoanyane, kahoo ka kakaretso, ka seoelo ho laola lebelo le leholo.Hobane motlakase o na le mefuta e mengata ea likopo 'me e ka sebelisoa ke mechine e mengata, ho hlokahala hore u fetole lebelo la eona ho ea ka liketsahalo tse fapaneng. Empa mokhoa oa taolo ea koloi oa brushless dc le taolo ea lebelo o hloka hore motho e mong le e mong a ithute, e le hore a sebelise kapele:
1. Ka ho laola tatellano eo coil e matlafalitsoeng ka eona, coil e hanyetsanang e arotsoe ka sehlopha 'me hona joale e matlafatsoa ho hlahisa matla a khoheli ka tsela e tšoanang.
2. Palo ea lipalo tsa brushless dc motor ke tse tharo, e le hore para e 'ngoe le e' ngoe ea "magnetic poles" e ka etsoa ka tatellano e itseng ho finyella phello ea ho potoloha ha matla a khoheli. bohareng kamehla ho na le tšekamelo ea ho boloka matla a khoheli ka lehlakoreng le le leng 'me a tla potoloha le matla a khoheli a potolohang.
H1H2H3 ke lisensara tse tharo tsa Holo tse behiloeng ka har'a lekhalo la moea la coil e tsosang takatso, e sebelisoang e le ntho ea ho lemoha matla a khoheli.Voltage e ka fetoloa ho latela tataiso ea matla a khoheli, 'me tlhahiso ke lets'oao la dijithale.
3. Coil ea stator e matlafatsoa ho ea ka tatellano e latelang, 'me matla a khoheli a rotor le matla a khoheli a stator a tlameha ho ba le Angle.Ha ho hlokahale ho ahlola hore na brushless dc motor e sa tsoa qala, e hloka feela ho phethahatsa taelo e latelang ho latela ho boemo ba ho sebetsa bo khutliselitsoeng ke sensor ea Holo.
Taelo ea eona ke ho romela lipara tse tharo tsa coil le ho tima, li-switches tsena li finyelloa ka transistor.
Ho potoloha ha mekhahlelo e meraro ea BLDC ho ka bonoa ka ho matlafatsa kapa ho khaola lipara tse tharo tsa transistors ka tatellano e itseng.
4. Ha rotor e ntse e potoloha, bokhoni bo susumelitsoeng ba coil e 'ngoe le e' ngoe bo tloha holimo ho ea holimo ho ea ho zero le ho khutlela morao hape. Hobane ha coil e matlafatsoa ka lehlakoreng le fapaneng, matla a motlakase a ka morao a tla thibela motlakase o ka morao, kahoo karolo ea maqhubu a trapezoidal e tla. hlaha.Motlakase o motle le o mobe oa karolo ea trapezoidal ea zero e fapane, kahoo boemo ba ho sebetsa ba motor stator bo ka khethoa ka ho lemoha matla a matle le a fosahetseng ka mor'a comparator ea motlakase.
Kaha ntlha ea zero e bohareng ba trapezoid, ho potoloha ha BLDC ho ka laoloa ka mor'a hore letšoao la taolo la tatellano ea nako e lumellanang le tsoe ka mor'a ho lieha ha 30 °. Mokhoa ona oa ho laola ha o hloke Hall sensor, 'me lithapo tse tharo li ka khona. khanna theBLDC.Haeba waveform e batla e loketse, li-curve tse tharo tsa li-coil voltage li ka fumanoa ka ho kopanya motlakase ka ho toba.Kahoo brushless dc motor e ka laoloa.
5. Etsa qeto ea tataiso ea ho qala, matlafatsa coil e ka tlaase ka tsela eo pele, etsa hore rotor e fetohele sebakeng sa ho qala ka nako e khutšoanyane, 'me u matlafatse motlakase ho ea ka tatellano e latelang ea liketso.
Bakeng sa ho ntlafatsa ts'ebeliso ea mochini oa brushless dc motor, re hloka ho ithuta ho latela tikoloho e fapaneng ea ts'ebeliso, taolo e fapaneng le taolo ea lebelo, ho ntlafatsa ts'ebeliso ea enjene, mokhoa oa taolo le lebelo o ka sebelisoa ho lokisa lebelo.
