Iminyaka eminingana, besibona ama-brushless motors eqala ukubusa idrayivu yamathuluzi angenazintambo embonini yamathuluzi ayingcweti.Lokhu kuhle, kodwa yini enkulu?Ingabe ibalulekile ngempela inqobo nje uma ngingakwazi ukushayela leso sikulufu sokhuni?um, yebo.Kunomehluko obalulekile kanye nemiphumela lapho usebenzisana nezinjini ezibhulashiwe kanye nama-brushless motors.
Ngaphambi kokuthi sijule kubhulashi elinezinyawo ezimbili kanye namamothoni angenalutho, ake siqale siqonde ulwazi oluyisisekelo lomgomo wangempela wokusebenza wama-DC motors.Uma kuziwa ekushayeleni izinjini, konke kuhlobene nozibuthe.Ozibuthe abashajwe ngokuphambene badonsana.Umqondo oyisisekelo wemoto ye-DC uwukugcina icala likagesi eliphambene lengxenye ejikelezayo (i-rotor) ikhangwe uzibuthe onganyakazi (i-stator) ephambi kwayo, ngaleyo ndlela idonsele phambili ngokuqhubekayo.Kucishe kufane nokubeka i-Boston Butter Donut othini phambi kwami uma ngigijima-ngizoqhubeka ngizama ukuyibamba!
Umbuzo uwukuthi ungawagcina kanjani ama-donuts ehamba.Ayikho indlela elula yokwenza.Iqala ngesethi yamazibuthe abangapheli (ozibuthe baphakade).Isethi yozibuthe kagesi ishintsha ishaja (ihlehlisa i-polarity) njengoba izungeza, ngakho kuhlale kunozibuthe ongunaphakade oneshaje ehlukile ekwazi ukuhamba.Ngaphezu kwalokho, ukushaja okufanayo okutholwa ikhoyili kagesi uma ishintsha kuzoyiphusha ikhoyili.Uma sibheka ama-motor brushed nama-brushless motors, ukuthi i-electromagnet ishintsha kanjani i-polarity kuyisihluthulelo.
Emotweni ebhulashiwe, kunezingxenye ezine eziyisisekelo: odonsa abangapheli, ama-armatures, izindandatho namabhulashi.Umazibuthe unomphela wakha ingaphandle lomshini futhi akanyakazi (i-stator).Enye ishajwe kahle kanti enye ishajwe kabi, idala inkambu kazibuthe ehlala njalo.
I-armature iyikhoyili noma uchungechunge lwamakhoyili aba yizibuthe kagesi uma inikwe amandla.Lena futhi ingxenye ejikelezayo (i-rotor), ngokuvamile eyenziwe ngethusi, kodwa i-aluminium ingasetshenziswa futhi.
Iringi yokuthutha igxilwe kukhoyili yengalo yezikhali ngamabili (ukumiswa kwezigxobo ezi-2), ezine (ukumiswa kwezigxobo ezi-4) noma izingxenye eziningi.Zizungeza nezikhali.Ekugcineni, amabhulashi ekhabhoni ahlala ekhona futhi adlulisele inkokhiso kumgibeli ngamunye.
Uma i-armature isinamandla, ikhoyili eshajiwe izodonselwa kumagnethi oshajwe ngokuphambene.Uma indandatho yesihambisi ngenhla nayo izungeza, isuka ekuxhumekeni kwebhulashi yekhabhoni eyodwa iye kwelandelayo.Uma ifika kubhulashi elilandelayo, izothola ukuguqulwa kwe-polarity futhi manje ikhangwa omunye uzibuthe ongunaphakade kuyilapho ixoshwa uhlobo olufanayo lokushaja kagesi.Ngokubonakalayo, lapho isihambisi sifika kubhulashi elinegethivu, manje sikhangwa uzibuthe oqondile unomphela.I-commutator ifika ngesikhathi ukuze yakhe uxhumano nebhulashi le-electrode elihle futhi ilandele kuzibuthe unomphela ongemuhle.Amabhulashi ahamba ngamabili, ngakho ikhoyili ephozithivu izodonsela kumagnethi, kanti ikhoyili enegethivu izodonsela kumagnethi ngesikhathi esifanayo.
Kufana nokuthi ngiyikhoyili yezikhali ngijaha i-Boston Butter Donut.Ngasondela, kodwa ngashintsha umqondo wami futhi ngaphishekela i-smoothie enempilo (i-polarity yami noma isifiso sami sashintsha).Phela, ama-donuts anothe ngama-kilojoule namafutha.Manje ngijaha ama-smoothies ngenkathi ngixoshwa e-Boston cream.Lapho ngifika lapho, ngabona ukuthi ama-donuts angcono kakhulu kunama-smoothies.Uma nje ngidonsa i-trigger, njalo lapho ngifika ebhulashini elilandelayo, ngizoshintsha umqondo wami futhi ngesikhathi esifanayo ngixoshe izinto engizithandayo embuthanweni ophithizelayo.Kuyisicelo esiphezulu se-ADHD.Ngaphezu kwalokho, sibabili lapho, ngakho-ke ama-Boston Butter Donuts nama-Smoothies ahlala ejahwa ngomunye wethu ngentshiseko, kodwa anqikaze.
Emotweni engenabhulashi, ulahlekelwa isihambisi namabhulashi futhi uthole isilawuli se-elekthronikhi.Imagnethi ehlala njalo manje isebenza njengerotha futhi izungeza ngaphakathi, kuyilapho i-stator manje seyakhiwe ikhoyili kagesi engaguquki yangaphandle.Isilawuli sinikeza amandla kukhoyili ngayinye ngokusekelwe eshadini elidingekayo ukuze lihehe uzibuthe ongunaphakade.
Ngokungeziwe ekuhambiseni amashaji nge-elekthronikhi, isilawuli singahlinzeka ngamashaji afanayo ukuze simelane nozibuthe baphakade.Njengoba amashaji ohlobo olufanayo ephambene, lokhu kuphusha uzibuthe unomphela.Manje i-rotor ihamba ngenxa yamandla okudonsa nokuphusha.
Kulokhu, omazibuthe baphakade bayanyakaza, ngakho manje sebengozakwethu abagijimayo kanye nami.Asisawushintshi umqondo walokho esikufunayo.Esikhundleni salokho, sasazi ukuthi ngifuna i-Boston Butter Donuts, futhi umlingani wami wayefuna ama-smoothie.
Izilawuli zama-elekthronikhi zivumela ubumnandi bethu besidlo sasekuseni ukuba buhambe phambi kwethu, futhi besilokhu siphishekela izinto ezifanayo ngaso sonke isikhathi.Isilawuli siphinde sibeke izinto esingafuni ngemuva ukuze sikunikeze ukuphusha.
Izinjini ezixutshiwe ze-DC zilula futhi zishibhile ukwenza izingxenye (yize ithusi lingashibhile).Njengoba i-brushless motor idinga i-electronic communicator, empeleni uqala ukwakha ikhompiyutha ngethuluzi elingenazintambo.Lesi yisizathu sokukhuphula izindleko zama-motorless brushless.
Ngenxa yezizathu zokuklama, ama-brushless motors anezinzuzo eziningi ngaphezu kwama-motor abhulashiwe.Iningi lazo lihlobene nokulahleka kwamabhulashi kanye nabagibeli.Njengoba ibhulashi lidinga ukuxhumana nomshayeli ukuze lidlulise ukushaja, liphinde libangele ukungqubuzana.I-Friction inciphisa isivinini esifinyelelekayo futhi ngesikhathi esifanayo ikhiqiza ukushisa.Kufana nokugibela ibhayisikili elinamabhuleki alula.Uma imilenze yakho isebenzisa amandla afanayo, ijubane lakho lizohamba kancane.Ngokuphambene, uma ufuna ukugcina isivinini, udinga ukuthola amandla engeziwe emilenzeni yakho.Uzofudumeza namarimu ngenxa yokushisa okushayisanayo.Lokhu kusho ukuthi, uma kuqhathaniswa namamotho ama-brushed, ama-brushless motors agijima ezingeni lokushisa eliphansi.Lokhu kuzinikeza ukusebenza kahle okuphezulu, ngakho-ke ziguqula amandla kagesi amaningi zibe amandla kagesi.
Amabhulashi ekhabhoni nawo azoguga ngokuhamba kwesikhathi.Yilokhu okubangela izinhlansi ngaphakathi kwamanye amathuluzi.Ukuze ugcine ithuluzi lisebenza, ibhulashi kufanele lishintshwe ngezikhathi ezithile.Amamotho angama-brushless awadingi lolu hlobo lokunakekelwa.
Nakuba ama-brushless motors adinga abalawuli be-electronic, inhlanganisela ye-rotor/stator ihlangene kakhulu.Lokhu kuholela emathubeni esisindo esilula kanye nosayizi ohlangene.Kungakho sibona amathuluzi amaningi afana nomshayeli womthelela we-Makita XDT16 onomklamo we-ultra-compact namandla anamandla.
Kubonakala kunokungaqondi mayelana nama-brushless motors kanye ne-torque.Idizayini ye-brushless motor ngokwayo ayikhombisi ngempela ubukhulu betorque.Isibonelo, i-torque yangempela ye-Milwaukee M18 fuel drill isando sikaphethiloli yayincane kunemodeli yangaphambili ebhulashiwe.
Nokho, ekugcineni umenzi wabona izinto ezibucayi kakhulu.Izinto zikagesi ezisetshenziswa kuma-brushless motors zinganikeza amandla engeziwe kulawa ma-motor uma kudingeka.
Njengoba ama-brushless motors manje asebenzisa isilawuli se-elekthronikhi esithuthukisiwe, ayakwazi ukuzwa lapho eqala ukwehla ngaphansi komthwalo.Inqobo nje uma ibhethri nemoto kungaphakathi kwebanga lokucaciswa kwezinga lokushisa, i-brushless motor electronics ingacela futhi yamukele okwamanje okwengeziwe ephaketheni lebhethri.Lokhu kuvumela amathuluzi afana nama-brushless drill namasaha ukugcina isivinini esiphezulu ngaphansi komthwalo.Lokhu kubenza basheshe.Ngokuvamile kuyashesha kakhulu.Ezinye izibonelo zalokhu zihlanganisa i-Milwaukee RedLink Plus, i-Makita LXT Advantage ne-DeWalt Perform and Protect.
Lobu buchwepheshe buhlanganisa kalula izinjini zamathuluzi, amabhethri, nezinto zikagesi zibe isistimu ehlangene ukuze kuzuzwe ukusebenza okuphelele nesikhathi sokusebenza.
Ukushintsha—shintsha i-polarity yokushaja—qalisa injini ye-brushless futhi uyigcine ijikeleza.Okulandelayo, udinga ukulawula isivinini kanye ne-torque.Ijubane lingalawulwa ngokushintsha i-voltage ye-BLDC motor stator.Ukushintsha i-voltage ngemvamisa ephezulu kukuvumela ukuthi ulawule isivinini semoto ngezinga elikhulu.
Ukuze ulawule i-torque, lapho umthwalo we-torque we-motor ukhuphuka ngaphezu kwezinga elithile, unganciphisa i-stator voltage.Kunjalo, lokhu kwethula izidingo ezibalulekile: ukuqapha motor kanye izinzwa.
Izinzwa ze-Hall-effect zinikeza indlela engabizi yokuthola indawo ye-rotor.Bangakwazi futhi ukubona isivinini ngesikhathi kanye nemvamisa yokushintshwa kwenzwa yesikhathi.
Inothi lomhleli: Bheka yethu Ithini indatshana yemoto engenazinzwa ukuze ufunde ukuthi ubuchwepheshe bezimoto ze-BLDC buwashintsha kanjani amathuluzi amandla.
Inhlanganisela yalezi zinzuzo inomunye umphumela-isikhathi eside sempilo.Nakuba iwaranti yama-brushless motors (namathuluzi) ngaphakathi komkhiqizo ngokuvamile iyafana, ungalindela impilo ende yamamodeli angenalutho.Lokhu ngokuvamile kungaba iminyaka eminingana ngemva kwesikhathi sewaranti.
Uyakhumbula ngenkathi ngithi izilawuli zikagesi zakha amakhompyutha kumathuluzi akho?Amamotho angama-Brushless nawo ayiphoyinti lempumelelo lamathuluzi ahlakaniphile okuthinta imboni.Ngaphandle kokuthembela kwamamotho e-brushless ekuxhumaneni ngogesi, ubuchwepheshe benkinobho eyodwa ye-Milwaukee ngeke busebenze.
Ewashini, uKenny uhlola ngokujulile ukulinganiselwa okusebenzayo kwamathuluzi ahlukahlukene futhi aqhathanise umehluko.Ngemva kokuphuma emsebenzini, ukholo lwakhe nothando lwakhe ngomndeni wakhe luyizinto eziza kuqala kuye.Ngokuvamile uzobe usekhishini, ugibele ibhayisikili (uyi-triathlon) noma ukhiphe abantu bayodoba usuku eTampa Bay.
