Igijima kanjani injini?
1) Imoto ijikeleza ngosizo lukazibuthe, amandla kazibuthe
Ngaphakathi kukazibuthe unomphela one-shaft ejikelezayo,① uzungezisa uzibuthe(ukukhiqiza insimu kazibuthe ejikelezayo),② ngokomgomo wezigxobo zika-N kanye no-S eziheha izigxobo eziphambene futhi zihlekise ezingeni elifanayo,③ uzibuthe one-shaft ejikelezayo izojikeleza.
Lesi yisimiso esiyisisekelo sokujikeleza kwezimoto.
Inkambu kazibuthe ezungezayo (amandla kazibuthe) ikhiqizwa eduze kwentambo lapho i-current igeleza ocingweni, futhi uzibuthe uzungeza, okuyisimo sokusebenza esifanayo.
Ukwengeza, lapho ucingo lulinyazwe ngesimo sekhoyili, amandla kazibuthe ahlangene, kwakhiwa i-flux magnetic field (magnetic flux), futhi i-N pole kanye ne-S pole ziyakhiqizwa.
Ngaphezu kwalokho, ngokufaka umgogodla wensimbi ocingweni olugoqiwe, kuba lula ukuthi amandla kazibuthe adlule kuwo, futhi kungenziwa amandla amakhulu kazibuthe.
2) Injini yangempela ejikelezayo
Lapha, njengendlela esebenzayo yokujikeleza kwemishini kagesi, indlela yokukhiqiza insimu yamagnetic ejikelezayo isebenzisa izigaba ezintathu ezishintshanayo zamanje namakhoyili ethulwa.
(Izigaba ezintathu ze-AC isignali ye-AC enesikhawu sesigaba esingu-120°)
- Isizinda sokwenziwa kazibuthe kusimo esingenhla ① sihambisana nesibalo esilandelayo ①.
- Inkambu kazibuthe esifundazweni ② ngenhla ihambisana ② emfanekisweni ongezansi.
- Inkambu kazibuthe yokwenziwa esifundazweni esingenhla ③ ihambisana nesibalo esilandelayo ③.
Njengoba kuchazwe ngenhla, inxeba lekhoyili elizungeze umgogodla lihlukaniswe izigaba ezintathu, futhi ikhoyili ye-U-phase, i-V-phase coil, ne-W-phase coil ihlelwa ngezikhathi ze-120 °.Ikhoyili enamandla kagesi aphezulu ikhiqiza isigxobo esingu-N, kanti ikhoyili ene-voltage ephansi ikhiqiza i-S pole.
Njengoba isigaba ngasinye sishintsha njengegagasi elinesine, i-polarity (N pole, S pole) ekhiqizwa ikhoyili ngayinye kanye nenkundla yayo kazibuthe (amandla kazibuthe) iyashintsha.
Ngalesi sikhathi, bheka nje ikhoyili ekhiqiza isigxobo sika-N, bese ushintsha ukulandelana kwekhoyili ye-U-phase → Ikhoyili yesigaba se-V→ ikhoyili yesigaba se-W→ ikhoyili yesigaba U, ngaleyo ndlela iyazungeza.
Ukwakheka kwenjini encane
Isithombe esingezansi sibonisa ukwakheka okujwayelekile nokuqhathaniswa kwamamotho amathathu: i-stepper motor, i-brushed direct current (DC) motor, kanye ne-brushless direct current (DC) motor.Izingxenye eziyisisekelo zalawa ma-motor ikakhulukazi amakhoyili, odonsa kanye nama-rotor.Ngaphezu kwalokho, ngenxa yezinhlobo ezahlukene, zihlukaniswe zibe uhlobo lwekhoyili olungaguquki kanye nohlobo olumisiwe lwamagnetic.
Okulandelayo incazelo yesakhiwo esihlobene nomdwebo oyisibonelo.Njengoba kungase kube nezinye izakhiwo ngesisekelo se-granular, sicela uqonde ukuthi isakhiwo esichazwe kulesi sihloko singaphakathi kohlaka olukhulu.
Lapha, ikhoyili ye-stepper motor igxiliwe ngaphandle, futhi i-magnet ijikeleza ngaphakathi.
Lapha, omagnethi bemoto ye-DC ebhulashiwe bagxiliwe ngaphandle, futhi amakhoyili azungeziswa ngaphakathi.Amabhulashi kanye ne-commutator banomthwalo wemfanelo wokunikeza amandla kukhoyili kanye nokushintsha isiqondiso se-current.
Lapha, ikhoyili ye-brushless motor igxiliwe ngaphandle, futhi i-magnet ijikeleza ngaphakathi.
Ngenxa yezinhlobo ezahlukene zama-motor, noma ngabe izingxenye eziyisisekelo zifana, isakhiwo sihlukile.Imininingwane izochazwa ngokuningiliziwe esigabeni ngasinye.
motor brushed
Isakhiwo se-brushed motor
Ngezansi indlela ebukeka ngayo i-DC motor evame ukusetshenziswa kumamodeli, kanye ne-schematic eqhumayo yezigxobo ezimbili ezijwayelekile (ozibuthe aba-2) enenjini yohlobo lwamakhoyili amathathu.Mhlawumbe abantu abaningi banesipiliyoni sokuqaqa injini nokukhipha uzibuthe.
Kuyabonakala ukuthi omazibuthe baphakade bemoto ye-DC ebhulashiwe balungisiwe, futhi amakhoyili emoto ebhulashiwe we-DC angazungeza isikhungo esingaphakathi.Uhlangothi olumile lubizwa ngokuthi "stator" kanti uhlangothi olujikelezayo lubizwa ngokuthi "rotor".
Okulandelayo umdwebo wohlelo lwesakhiwo esimele umqondo wesakhiwo.
Kunabagibeli abathathu (amashidi ensimbi agobile okushintsha kwamanje) kumngcele we-eksisi emaphakathi ezungezayo.Ukuze ugweme ukuthintana, abagibeli bahlelwa ngesikhawu esingu-120° (360°÷3 izingcezu).I-commutator iyazungeza njengoba shaft izungeza.
I-commutator eyodwa ixhunywe ne-coil end eyodwa kanye ne-coil end, futhi abagibeli abathathu namakhoyili amathathu bakha yonke (ring) njengenethiwekhi yesekethe.
Amabhulashi amabili amiswe ku-0° naku-180° ukuze axhumane nomgibeli.Ugesi wangaphandle we-DC uxhunywe kubhulashi, futhi owamanje ugeleza ngokuvumelana nendlela yebhulashi → isihambisi → ikhoyili → ibhulashi.
Umgomo wokuzungezisa wemoto ebhulashiwe
① Zungezisa ngokuphikisana newashi ukusuka kusimo sokuqala
Ikhoyili A ingaphezulu, xhuma amandla ebhulashi, kwesokunxele kube (+) futhi kwesokudla kube (-).I-current enkulu igeleza isuka ebhulashini elingakwesobunxele iye ku-A ikhoyili ku-commutator.Lesi yisakhiwo lapho ingxenye engaphezulu (uhlangothi olungaphandle) lwekhoyili A iba yi-S pole.
Njengoba i-1/2 yamanje yekhoyili A igeleza isuka ebhulashini lesokunxele iye kukhoyili B kanye nekhoyili C kwelinye icala ukuya kukhoyili A, izinhlangothi zangaphandle zekhoyili B kanye nekhoyili C ziba izigxobo ezibuthakathaka zika-N (okuboniswa ngamagama amancane kancane umfanekiso).
Amandla kazibuthe adalwe kulawa makhoyili kanye nemiphumela enyanyekayo nekhangayo kamazibuthe ibeka amakhoyili amandla ajikelezayo aphikisana newashi.
② Phendula ngokuphambene newashi
Okulandelayo, kucatshangwa ukuthi ibhulashi elilungile lixhumene nabagibeli ababili esimweni lapho ikhoyili A izungeziswe ngokuphikisana newashi ngo-30°.
Umsinga wekhoyili A uqhubeka ugeleza usuka ebhulashini lesokunxele uya ebhulashini elingakwesokudla, kanti ingaphandle lekhoyili ligcina isigxobo sika-S.
Igagasi elifanayo njengeKhoyili A ligeleza kuKhoyili B, kanti ingaphandle leKhoyili B liba yi-N pole enamandla.
Njengoba zombili iziphetho zekhoyili C zifinyezwa amabhulashi, akukho ukugeleza kwamanje futhi akukho mkhakha kazibuthe okhiqizwayo.
Nakulokhu, amandla okuzungeza okuphambene newashi ayatholakala.
Ukusuka ku-③ kuye ku-④, ikhoyili engenhla iyaqhubeka nokuthola amandla kwesokunxele, futhi ikhoyili engezansi iyaqhubeka nokuthola amandla kwesokudla, futhi iyaqhubeka nokuzungezisa ngokuphambene newashi.
Lapho ikhoyili izungeziswa ukuze ③ futhi ④ njalo ku-30°, lapho ikhoyili ibekwe ngaphezu kwe-eksisi evundlile emaphakathi, uhlangothi lwangaphandle lwekhoyili luba isigxobo sika-S;lapho ikhoyili ibekwe ngezansi, iba yi-N pole, futhi lokhu kunyakaza kuyaphindwa.
Ngamanye amazwi, ikhoyili engenhla iphoqelelwa ngokuphindaphindiwe kwesokunxele, futhi ikhoyili ephansi iphoqeleka ngokuphindaphindiwe kwesokudla (kokubili ngendlela ephikisana newashi).Lokhu kugcina i-rotor ijikeleza ngokuphambene newashi ngaso sonke isikhathi.
Uma uxhuma amandla ngakolunye uhlangothi lwesobunxele (-) kanye namabhulashi angakwesokudla (+), kwakhiwa izindawo eziphambene kazibuthe kumakhoyili, ngakho amandla asetshenziswa kumakhoyili nawo abheke kolunye uhlangothi, ajike ngokulandela iwashi.
Ngaphezu kwalokho, lapho amandla ecishiwe, i-rotor ye-brush motor iyayeka ukujikeleza ngenxa yokuthi ayikho insimu kazibuthe yokuyigcina ijikeleza.
