Isimiso sokusebenza sokubhoboza kagesi okuxutshwe

I-HammerI-Drill 28MMisakhiwo esiyinhloko sokuprakthiza kukagesi okuxutshwe yi-stator + rotor + amabhulashi, athola i-torque ejikelezayo endaweni yamagnetic ejikelezayo, ngaleyo ndlela ikhiphe amandla e-kinetic.Ibhulashi nesihambisi ziyathintana njalo futhi ziyangqubuzana, futhi zidlala indima yokuqhuba nokushintsha ngesikhathi sokuzungezisa.

I-brushed drill kagesi ithatha ukushintsha kwemishini, isigxobo kazibuthe asinyakazi, futhi ikhoyili iyajikeleza.Uma i-drill kagesi isebenza, ikhoyili ne-commutator ziyazungeza, kodwa insimbi kazibuthe nebhulashi lekhabhoni azijikelezi.Isiqondiso samanje esishintshayo sekhoyili sishintshwa yi-inverter kanye nebhulashi likagesi elizungeza nge-drill kagesi.

Kule nqubo, iziphetho ezimbili zokufaka amandla ekhoyili zihlelwa ngendandatho ngokushintshana, zihlukaniswe komunye nomunye ngezinto zokuvikela ukuze zenze isilinda, esixhunywe ku-drill shaft kagesi.Ukunikezwa kwamandla kwenziwa ngezinto ezimbili ze-carbon.Izinsika ezincane (amabhulashi ekhabhoni), ngaphansi kokucindezela kwentwasahlobo, cindezela amaphuzu amabili kusilinda esingaphezulu samandla wekhoyili wokufaka amandla asuka ezindaweni ezimbili eziqondile ukuze unike ikhoyili amandla.

Njengoba i-drill kagesi izungeza, amakhoyili ahlukene noma izigxobo ezimbili zekhoyili efanayo zinikwa amandla ngezikhathi ezihlukene, ukuze isigxobo se-NS sekhoyili ekhiqiza amandla kazibuthe kanye nesigxobo se-NS sikazibuthe oseduze unomphela we-stator unomehluko ofanele we-engeli., Khiqiza amandla okuphusha umshini kagesi ukuze ujikeleze.I-carbon electrode islayida kutheminali yekhoyili, njengebhulashi ebusweni bento, ngakho ibizwa ngokuthi “ibhulashi” lekhabhoni.

Okubizwa ngokuthi "amabhulashi aphumelelayo, ukwehluleka nakho kuyabhulashi."Ngenxa ye-mutual sliding, amabhulashi ekhabhoni azokhuhlwa, okubangele ukulahlekelwa.Ukukhanyisa nokuvala amabhulashi ekhabhoni kanye namatheminali ekhoyili kuzoshintshana, futhi kuyovela izinhlansi zikagesi, kuzokwenziwa ukuphuka kwe-electromagnetic, futhi izinto zikagesi zizophazanyiswa.Ngaphezu kwalokho, ngenxa yokushelela nokushwibilika okuqhubekayo, amabhulashi azoguga njalo abuye abe yicala lokubhoboza ibhulashi lesikhashana.

Uma ibhulashi lilimele, lidinga ukulungiswa, kodwa ingabe kuyoba nzima ukulilungisa ngokuphindaphindiwe?Eqinisweni, ngeke, kodwa bekungeke yini kube ngcono uma kukhona i-drill kagesi engadingi ukushintsha ibhulashi?Lona i-brushless drill.

Umgomo wokusebenza we-brushless drill kagesi

I-brushless electric drill, njengoba negama liphakamisa, i-drill kagesi ngaphandle kwebhulashi likagesi.Manje njengoba lingekho ibhulashi likagesi, i-drill kagesi ingaqhubeka kanjani isebenza?

Kuvele ukuthi ukwakheka kwe-brushless drill kagesi kuphambene ncamashi ne-brushed electric drill:

Ku-drill kagesi ye-brushless, umsebenzi wokushintsha uqedwa yisekethe yokulawula kusilawuli (imvamisa inzwa ye-Hall + isilawuli, ubuchwepheshe obuthuthuke kakhulu buyisishumeki kazibuthe).

I-brushed drill kagesi ine-pole magnetic engaguquki futhi ikhoyili iyajika;i-brushless drill kagesi inekhoyili engashintshi futhi isigxobo kazibuthe siyajika.Ku-drill kagesi ye-brushless, inzwa yeHholo isetshenziselwa ukuzwa indawo yesigxobo kazibuthe sikazibuthe ongunaphakade, bese ngokwalo mbono, isekethe ye-elekthronikhi isetshenziselwa ukushintsha indlela yamanje ekhoyili ngesikhathi esifanele. ukuqinisekisa ukuthi amandla kazibuthe asendleleni efanele akhiqizwa ukushayela umshini wokubhoboza kagesi.Susa ukushiyeka kokusebenza kukagesi okuxutshwe.

Lawa masekhethi angabalawuli be-brushless drill kagesi.Bangakwazi futhi ukwenza imisebenzi ethile engakwazi ukufezeka ngokubhoboza kagesi okubhulashiwe, njengokulungisa i-angle yokushintsha amandla, ukubhuleka i-drill kagesi, ukwenza i-drill kagesi ihlehle, ikhiye i-drill kagesi, nokusebenzisa isignali yebhuleki ukuze kumiswe ukunika amandla i-drill kagesi. ..I-alamu yokukhiya yemoto yebhethri manje isebenzisa ngokugcwele le misebenzi.
