Umgaqo wokusebenza we-brushed drill yombane

IHammerUkuqhuba 28MMIsakhiwo esiphambili se-drill yombane ebrashiweyo yi-stator + rotor + iibrashi, ezifumana i-torque ejikelezayo kwintsimi yamagnetic ejikelezayo, ngaloo ndlela ikhupha amandla e-kinetic.I-brush kunye ne-commutator zidibanisa rhoqo kunye ne-friction, kwaye zidlala indima yokuqhubela phambili kunye nokuguqulwa ngexesha lokujikeleza.

I-brushed drill yombane ithatha ukuguqulwa komatshini, i-pole magnetic ayishukumi, kwaye ikhoyili iyajikeleza.Xa i-drill yombane isebenza, i-coil kunye ne-commutator iyajikeleza, kodwa intsimbi yamagnetic kunye ne-carbon brush ayijikelezi.Isalathiso sangoku esitshintshileyo sekhoyili sitshintshwa yi-inverter kunye nebrashi yombane ejikelezayo nge-drill yombane.

Kule nkqubo, iziphelo zokufaka amandla amabini ekhoyili zicwangciswe kwindandatho ngokulandelelana, zihlulwe omnye komnye ngezinto ezikhuselayo zokwenza i-cylinder, edibaniswe ne-drill shaft yombane.Unikezelo lwamandla lwenziwe ngezinto ezimbini zekhabhoni.Iintsika ezincinci (iibhrashi zekhabhoni), phantsi kwentshukumo yoxinzelelo lwasentwasahlobo, cinezela amanqaku amabini kwi-cylinder yegalelo lamandla ecoil ephezulu ukusuka kwizikhundla ezibini ezimiselweyo ukunika amandla ikhoyili.

Njengoko i-drill yombane ijikeleza, iikhoyili ezahlukeneyo okanye izibonda ezimbini zekhoyili efanayo zinamandla ngamaxesha ahlukeneyo, ukwenzela ukuba i-NS pole yekhoyili evelisa intsimi yamagnetic kunye ne-NS pole ye-stator esondeleyo yemagnethi esisigxina inomahluko ofanelekileyo we-engile., Ukuvelisa amandla okutyhala i-drill yombane ukujikeleza.I-carbon electrode isilayidi kwi-terminal yekhoyili, njengebrashi ebusweni bento, ngoko ibizwa ngokuba yi-carbon "brush".

Oko kubizwa ngokuba "iibrashi eziyimpumelelo, ukungaphumeleli kunye neebrashi."Ngenxa ye-mutual sliding, iibrashi zekhabhoni ziya kuxutywa, zibangele ilahleko.Ukuvula kunye nokuvala iibhrashi zekhabhoni kunye neetheminali zekhoyili ziya kutshintshana, kwaye kuya kwenzeka iintlantsi zombane, ukuqhekeka kwe-electromagnetic kuya kuveliswa, kunye nezixhobo zombane ziya kuphazamiseka.Ngaphaya koko, ngenxa yokutyibilika okuqhubekayo kunye nokukhuhlana, iibhrashi ziya kuhlala zinxitywa rhoqo kwaye zikrazuka zikwangunobangela wokuqhutywa kwebrashi yexeshana elifutshane.

Ukuba i-brush yonakele, kufuneka ilungiswe, kodwa ngaba kuya kuba nzima ukuyilungisa ngokuphindaphindiweyo?Ngapha koko, ayizukuba njalo, kodwa ngaba bekungayi kuba ngcono ukuba kukho i-drill yombane engadingi kutshintsha ibrashi?Le yibrushless drill.

Umgaqo osebenzayo we-brushless drill yombane

I-Brushless drill yombane, njengoko igama libonisa, yi-drill yombane ngaphandle kwebrashi yombane.Ngoku ukuba akukho brashi yombane, i-drill yombane ingaqhubeka njani isebenza?

Kuyavela ukuba ulwakhiwo lwe-brushless drill yombane luchasene ngqo nolwe-brush yombane:

Kwi-drill yombane ye-brushless, umsebenzi wokutshintshwa ugqitywe yisiphaluka solawulo kumlawuli (ngokuqhelekileyo i-Hall sensor + controller, iteknoloji ephezulu kakhulu yi-encoder magnetic).

I-brushed drill drill ine-pole magnetic engaguqukiyo kwaye i-coil iyajika;i-brushless drill yombane ine-coil esisigxina kunye ne-pole magnetic ijika.Kwi-drill yombane ye-brushless, i-sensor yeHolo isetyenziselwa ukuva indawo yepoli yemagnethi yemagnethi esisigxina, kwaye ngokuhambelana nale ngcamango, isekethe ye-elektroniki isetyenziselwa ukutshintsha indlela yangoku kwikhoyili ngexesha elifanelekileyo. ukuqinisekisa ukuba amandla kazibuthe kwicala elichanekileyo iveliswa ukuqhuba i-drill yombane.Ukuphelisa ukusilela kwi-brushed drills yombane.

Ezi zijikelezo ngabalawuli bee-brushless drills zombane.Banokuphumeza eminye imisebenzi engenakufezekiswa ngokuqhutywa kombane okubrashiweyo, njengokuhlengahlengisa i-angle yokutshintshela amandla, ukuqhobosha i-drill yombane, ukwenza i-drill drill ibuyele umva, ukutshixa i-drill yombane, kunye nokusebenzisa isignali ye-brake ukuyeka ukunika amandla i-drill yombane. ..Isitshixo se-alam ye-elektroniki yemoto yebhetri ngoku sisebenzisa ngokupheleleyo le misebenzi.
