Uyini umgomo wokusebenza we-BLDC motor?-1

I-brushless DC motor (BLDC)iyinjini esebenzisa ubuchwepheshe be-electronic commutation. Ifinyelela isivinini esinembile nokulawula isikhundla ngokulawula okunembile kwe-elekthronikhi, okwenza i-brushless DC motor isebenze kahle futhi ithembeke. Lobu buchwepheshe bokushintshwa kwe-elekthronikhi buqeda ukungqubuzana kwebhulashi nokulahlekelwa amandla kumamotho endabuko e-DC abhulashiwe, okuwavumela ukuthi asebenze kahle kakhulu. Umgomo wayo wokusebenza usekelwe ku-electromagnetic induction kanye nobuchwepheshe bokuhamba nge-elekthronikhi. Uma kuqhathaniswa namamotho endabuko e-DC abhulashiwe, ama-brushless DC motors afinyelela ukuhamba nge-elekthronikhi ngezinzwa ezakhelwe ngaphakathi nezilawuli, ngaleyo ndlela azuze ukusebenza kahle okuphezulu, umsindo ophansi kanye nokusebenza okuphansi kokulungisa.

Amamotho e-Brushless DC ngokuvamile aqukethe i-rotor, i-stator, izinzwa nesilawuli. I-rotor ngokuvamile yenziwe ngezinto ezisebenza uzibuthe, kuyilapho i-stator iqukethe amakhoyili ocingo. Lapho i-current idlula ikhoyili ye-stator, inkambu kazibuthe ekhiqizwayo isebenzisana nezinto ezisetshenziswa uzibuthe unomphela ku-rotor, ngaleyo ndlela ikhiqize i-torque ukuze ishayele i-rotor ukuthi ijikeleze. Izinzwa zivame ukusetshenziselwa ukubona indawo kanye nesivinini se-rotor ukuze isilawuli sikwazi ukulawula ngokunembile isiqondiso nobukhulu bamanje. Isilawuli siwubuchopho be-brushless motor. Isebenzisa imininingwane yempendulo evela kwinzwa ukuze ifinyelele ukushintshwa kwe-elekthronikhi okunembayo, ngaleyo ndlela ishayele injini ukuthi isebenze kahle.

Inqubo yokusebenza ye-brushless DC motor ingahlukaniswa ngezigaba eziningana: okokuqala, lapho okwamanje idlula ikhoyili ye-stator, inkambu kazibuthe ekhiqiziwe ixhumana nezinto ezihlala unomphela zikazibuthe ku-rotor ukukhiqiza i-torque ukushayela i-rotor ukujikeleza. Okwesibili, inzwa ithola isikhundla nesivinini se-rotor futhi iphakele ulwazi emuva kumlawuli. Isilawuli silawula ngokunembile isiqondiso nosayizi wamanje ngokusekelwe kulwazi lwempendulo evela kunzwa ukuze kuzuzwe isikhundla esinembile nokulawula isivinini se-rotor. Ekugcineni, ngokusekelwe kulwazi lwesikhundla kanye nesivinini se-rotor, isilawuli silawula ngokunembile isiqondiso nobukhulu bamanje ukuze kuzuzwe ukushintshwa kwe-elekthronikhi, ngaleyo ndlela ngokuqhubekayo ushayela i-rotor ukuze ijikeleze.

Uma kuqhathaniswa namamotho endabuko e-DC axutshwe, ama-brushless DC motors asebenza kahle kakhulu nokuthembeka, ngakho asetshenziswe kabanzi emikhakheni eminingi. Embonini yezimoto, yethuSinbadama-brushless DC motors asetshenziswa ezinhlelweni zokushayela zezimoto zikagesi. Ukusebenza kwabo okuphumelelayo nokuthembekile kwenza izimoto zikagesi zifinyelele ibanga elide lokuhamba kanye nokusheshisa ngokushesha. Emkhakheni wezinto zikagesi zasendlini, ama-motor e-DC e-Sinbad brushless asetshenziswa ezintweni zasendlini ezihlukahlukene, njengemishini yokuwasha, izicoci ze-vacuum, njll. Umsindo wawo ophansi nokusebenza kahle okuphezulu kwenza izinto zikagesi zasekhaya zonge kakhulu amandla futhi zivumelane nemvelo. Ngaphezu kwalokho, ama-brushless DC motors nawo asetshenziswa kabanzi ku-automation yezimboni, i-aerospace, ama-drones neminye imikhakha.
