Uyawazi umahluko phakathi kwe-brushless motor ne-brush ye-motor
Thelekisa ii-brushless kunye ne-brushless motors
Umahluko kumgaqo wokufakelwa kombane phakathi kwe-brushless motor kunye ne-brushless motor: i-brushless motor isebenzisa i-carbon brush kunye ne-commutator ukwenza i-commutator yomatshini, ngelixa i-brushless motor isebenzisa i-signal element induction yokugqiba i-commutator ye-elektroniki ngumlawuli.
Iimoto ezingenakubrashi kunye nebrashi zinemigaqo eyahlukeneyo yombane kunye nolwakhiwo lwangaphakathi. Iimoto zehabhu, indlela yokuphuma yetorque yemoto (nokuba iyacaciswa ngesixhobo sokunciphisa izixhobo) yahlukile, kunye nobume bayo boomatshini bohlukile.
Ulwakhiwo lwangaphakathi olwenziwe ngesantya esiphezulu sebrashi yemoto. Uhlobo lwehabhu leemoto luqukethe isantya esiphezulu sebrashi yemoto, iseti yokunciphisa izixhobo, iklatshi ebambe ongezantsi, ikepusi yehabhu kunye nezinye izinto. Isantya esiphezulu sebrashi kunye ne-gear hub yeemoto yeyangaphakathi kwirotor motor.
I-2, isantya esisezantsi esiqhelekileyo sokuxubha imoto esenziwe ngaphakathi. Olu hlobo lwe-hub-motor lwenziwe ngebrashi yekhabhoni, isiguquli sesigaba, i-motor rotor, i-motor stator, i-motor shaft, ikhava yokuphela kwemoto, ukuthwala kunye nezinye izinto. Isantya esisezantsi esinebrashi yehabhu engenamoto yeyomatshini ongaphandle wevili.
3.Umatshini wangaphakathi womatshini oqhelekileyo ohamba ngesantya esiphezulu. Uhlobo lwehabhu leemoto luqukethe isantya esingaphezulu sebrashi esine-motor, i-roller ye-friction roller, i-clutch egqithisileyo, ukuphuma kwesikhuselo, ikhava yokuphela, indawo yokuhlala kunye nezinye izinto. Isantya esiphakamileyo se-motor brushless hub sise-motor rotor yangaphakathi.
Ulwakhiwo lwangaphakathi olwenziwe ngesantya esiphantsi sebrashi. Uhlobo lwehabhu leemoto lwenziwe ngevili lemoto, i-motor stator, ishafti yemoto, ikhava yokuphela kwemoto, ethwele kunye nezinye izinto. Isantya esisezantsi esinebrashi kunye nezixhobo zohlobo lwehabhu zegiya yeyomatshini wangaphandle weRotor.
Umgaqo osebenzayo weemoto
Iimoto sisixhobo esiguqula amandla ombane abe ngamandla oomatshini. Umazibuthe ojikelezayo uveliswa yikhoyili yangoku (i-stator ejija) kwaye isetyenziselwa isakhelo sokuvalwa kwe-aluminium yesikwere ukwenza ifom ejikelezayo yamandla ombane. Ngokwemithombo eyahlukeneyo yamandla, iimoto zombane zahlulwe zangumatshini we-dc kunye nemoto ye-ac. Uninzi lwee-motor zombane kwinkqubo yamandla zii-ac motors, ezinokuthi zibe ziimotor ezihambelanayo okanye ii-asynchronous motors (isantya sendawo yemagnethi yesantya kunye nesantya sokujikeleza asigcini isantya esihambelanayo). Imoto ikakhulu iqulunqwe stator kunye Rotor, kwaye ulwalathiso intshukumo ngamandla yocingo lokuqhuba endle ngemagneti inxulumene ulwalathiso lwangoku kunye nolwalathiso umgca induction magnetic (ulwalathiso kumazibuthe). Umgaqo wokusebenza kwemoto yintsimi yamagnetic kumandla okwangoku, yenza ukujikeleza kwemoto.
Ezona mpawu ziphambili
Imoto yebrushless dc isetyenziswa ngokubanzi kwizithuthi zombane kuba inezi zinto zimbini zilandelayo xa kuthelekiswa nemoto yendalo ye-brushless dc motor.
(1) ubomi inkonzo ende, ulondolozo-free nokuthembeka eliphezulu. Kwi-brush ye-dc motor, kuba isantya seemoto siphezulu, ibrashi kunye ne-commutator inxiba ngokukhawuleza, umsebenzi oqhelekileyo ojikeleze iiyure ezili-1000 kufuneka ubeke endaweni yebrashi. Ukongeza, ubunzima bezobuchwephesha kwibhokisi yokunciphisa izixhobo bukhulu ngakumbi, ngakumbi ingxaki yokuthambisa kwezixhobo zokudlulisela, eyingxaki enkulu kwisikim sebrashi sangoku. Ke kukho ingxolo yebrashi yemoto, ukusebenza kancinci, kulula ukuvelisa iingxaki ezinje ngokusilela. Ke izibonelelo ze-brushless dc motor zicacile.
(2) ukusebenza okuphezulu nokonga umbane. Ngokubanzi, ukusebenza kwe-brushless dc motor kungangaphezulu kwama-85% ngenxa yokungabikho kwempixano yelahleko yokuhamba komatshini, ukusetyenziswa kwebhokisi yezixhobo, kunye nelahleko yesantya esilawula isekethe. Nangona kunjalo, kuthathelwa ingqalelo eyona ndleko isebenzayo kuyilo lokwenyani, ukwenzela ukunciphisa ukusetyenziswa kwezinto, uyilo ngokubanzi ngama-76%. Ukusebenza ngokukuko kwe-brushless dc motors ngenxa yokusetyenziswa kwebhokisi yebhokisi kunye ne-clutch egqithisileyo ihlala ijikeleze i-70%.
Iimpazamo eziqhelekileyo
Iimpazamo eziqhelekileyo ezine-brushless dc motors zihlala zivavanywa kwizinto zazo ezintathu. Xa indawo enesiphoso ingacacanga, isiqu semoto kufuneka sihlolwe kuqala, silandelwe sisixhobo sokuma, kwaye ekugqibeleni sijonge isekethe yolawulo lokuqhuba. Kumzimba weemoto kunokubonakala
Ingxaki yile: A, motor jiko zoqhakamshelwano embi, eyaphukileyo okanye elifutshane wesekethe. Iyakwenza ukuba imoto ingajiki; Imoto ingaqala kwezinye iindawo, kodwa ayinakuqala kwezinye iindawo; Imoto iphelile. Idemagnetization yepali ephambili yemagnethi yombane iya kwenza ukuba torque yemoto icace ukuba incinci, ngelixa isantya sokungabikho komthwalo siphezulu kwaye okwangoku sikhulu. Kwi-sensor yendawo, iingxaki eziqhelekileyo kukungonakali kweholo, ukungahambi kakuhle, ukutshintsha indawo, kuya kwenza ukuba i-motor ikhuphe i-torque encinci, enzulu iya kwenza ukuba i-motor ingashukumi okanye idibanise emva nangexesha elithile. Isitshintshi samandla sesona sinomdla wokungaphumeleli kwisekethe yolawulo lwedrive, okt, itransistor yamandla yonakele ngenxa yokugcwala kwexesha elide, ngaphezulu kwamandla okanye isekethe emfutshane. Oku kungasentla kuhlalutyo olulula lweziphene eziqhelekileyo zemoto engasebenziyo, ekusebenzeni kweemoto kuya kuba neengxaki ezahlukeneyo, abahloli kufuneka banike ingqwalaselo kule meko, hayi kumandla angacwangciswanga, ukuze angonakalisi. kwamanye amacandelo eemoto.
