1,Yiziphi izici ze-bipolar kanye ne-unipolar zenjini?
AmaMoto e-Bipolar:
Ama-motor ethu e-bipolar ngokuvamile anezigaba ezimbili kuphela, isigaba A nesigaba B, futhi isigaba ngasinye sinezintambo ezimbili eziphumayo, ezigoqekayo ezihlukene. Akukho ukuxhumana phakathi kwezigaba ezimbili. Ama-motor e-bipolar anezintambo ezine eziphumayo.
Ama-motor a-Unipolar:
Amamotha ethu e-unipolar ngokuvamile anezigaba ezine. Ngokusekelwe ezigabeni ezimbili zamamotha e-bipolar, kunezelwa imigqa emibili evamile.
Uma izintambo ezivamile zixhunywe ndawonye, izintambo eziphumayo ziyizintambo ezi-5.
Uma izintambo ezivamile zingaxhunywanga ndawonye, izintambo eziphumayo ziyizintambo ezi-6.
Injini ye-unipolar inemigqa emi-5 noma emi-6 ephumayo.
2,Iyini imvamisa yokusebenza ephezulu/imvamisa ephezulu yokukhipha？
Imvamisa ephezulu yokusebenza/Imvamisa ephezulu yokudonsa
Imvamisa yokusebenza ephezulu, eyaziwa nangokuthi imvamisa ephezulu yokushefa / imvamisa ephezulu yokudonsa, imvamisa ephezulu lapho imoto ingaqhubeka nokujikeleza ngaphansi kwefomu elithile lokushayela, i-voltage kanye nogesi olinganiselwe, ngaphandle kokwengeza umthwalo.
Ngenxa yokungabi namandla kwe-rotor, injini ejikelezayo idinga i-torque encane ukuze ijikeleze uma kuqhathaniswa nenjini engashintshi, ngakho-ke imvamisa yokusebenza ephezulu izoba nkulu kunemvamisa ephezulu yokuziqala.
3,Iyini i-torque yokudonsa kanye ne-torque yokudonsa yemoto ye-stepper?
I-torque yokukhipha
I-torque yokudonsa yi-torque ephezulu kakhulu engalethwa ngaphandle kokulahlekelwa yizinyathelo. Ifinyelela kuyo
esiphezulu ngesivinini noma imvamisa ephansi kakhulu, futhi iyancipha njengoba imvamisa ikhuphuka. Uma umthwalo ku-
Injini yokunyathela ngesikhathi sokujikeleza iyanda ngale kwe-torque yokudonsa, imoto izowa esitebhisini
futhi ukusebenza okunembile ngeke kwenzeke.
I-torque yokudonsa
I-torque yokudonsa yi-torque ephezulu kakhulu lapho injini ingaqala ukujikeleza khona ngemvamisa ethile kusukela
isimo sokuma. I-stepper ayikwazi ukuqala ukujikeleza nge-torque yomthwalo edlula i-torque yokudonsa.
I-torque yokudonsa incane kune-torque yokudonsa, ngenxa yokungabi namandla kwe-rotor yemoto.
4,Iyini i-torque yokuzibeka yemoto ye-stepper?
I-torque eqondile yi-torque ekhona esimweni sokungasebenzi kahle ngenxa yokusebenzisana kwe-permanent
omaginethi namazinyo e-stator. Ukuphazamiseka okuphawulekayo noma ukugoba kungazwakala ngokujikelezisa injini
isandla. Ngokuvamile, injini ye-stepper izolahlekelwa ukuvumelanisa lapho i-torque yokudonsa idlula ngenxa
ukulayisha ngokweqile. Ama-motor avame ukukhethwa futhi ahlolwe kusetshenziswa amanani e-torque okudonsa ngaphezu kwe-
izidingo zesicelo sokuvimbela ukulahleka kokubalwa noma izindawo zokupaka izimoto.
5,Yiziphi izindlela zokushayela zama-stepper motors?
Ukushayela ngegagasi/ngesigaba esisodwa kusebenza ngesigaba esisodwa kuphela
ivuliwe ngesikhathi, eboniswe esithombeni ohlangothini lwesokudla. Lapho idrayivu inika amandla ipali A (ipali yaseningizimu) eboniswe ngombala oluhlaza okotshani, idonsela ipali yasenyakatho yerotor. Lapho idrayivu inika amandla u-B futhi icima u-A, i-rotor ijikeleza ama-90 ° futhi lokhu kuyaqhubeka njengoba idrayivu inika amandla ipali ngayinye ngesikhathi.
Ukushayela Ngezigaba Ezi-2-2 kunegama layo ngoba izigaba ezimbili zivuliwe ngesikhathi esisodwa. Uma idrayivu inika amandla izigaba ezimbili ze-A ne-B njengezigxobo zaseningizimu (eziboniswe ngombala oluhlaza), khona-ke i-north pole ye-rotor idonsela kuzo zombili ngokulinganayo futhi iqondane phakathi kwalezi ezimbili. Njengoba ukulandelana okunika amandla kuqhubeka kanje, i-rotor igcina iqondana phakathi kwezigxobo ezimbili. Ukushayela ngezigaba ezimbili-2 akutholi sisombululo esihle kune-one-phase on, kodwa kukhiqiza i-torque eyengeziwe. Lena yindlela yokushayela esiyisebenzisa kakhulu ezivivinyweni zethu, eyaziwa nangokuthi "ukushayela ngesinyathelo esigcwele".
Ukushayela ngesigaba esingu-1-2 kuqanjwe ngemuva kokuthi umshayeli eshintsha phakathi kwesigaba esingu-1 kanye nesigaba esingu-2 sokuvuselela. Umshayeli unika amandla i-pole A, bese enika amandla zombili izigxobo A no-B, bese enika amandla i-pole B, bese enika amandla zombili izigxobo A no-B, njalo njalo. (Kuboniswe engxenyeni eluhlaza ohlangothini lwesokudla) Ukushayela ngesigaba esingu-1-2 kunikeza isinqumo sokunyakaza esingcono. Uma izigaba ezimbili zinikwe amandla, injini ine-torque eyengeziwe. Nasi isikhumbuzo: I-torque ripple iyinkinga, ngoba ingabangela ukuzwakala nokudlidliza. Uma kuqhathaniswa nokushayela okugcwele/ukushayela ngesigaba esingu-2-2, i-engeli yesinyathelo sokushayela ngesigaba esingu-1-2 ihlukaniswa phakathi kuphela, futhi kuthatha izinyathelo ezimbili ukujikeleza ukujikeleza okukodwa, ngakho-ke ukushayela ngesigaba esingu-1-2 kubizwa nangokuthi “ukushayela ngesinyathelo esiphakathi” Ukushayela ngesigaba esingu-1-2 kungabhekwa njengokushayela okuyisisekelo kakhulu kokuhlukanisa.
6，Ungayikhetha kanjani imoto ye-stepper efanelekile?
Ukuze uthole ukukhetha okuhle kakhulu, lezo
imithetho eyisisekelo yemfundiso kufanele ihlonishwe:
Umsebenzi wokuqala ukukhetha injini ye-stepper efanele yohlelo lokusebenza.
1. Khetha injini ngokusekelwe ku-torque/iphuzu lesivinini esiphezulu elidingwa uhlelo lokusebenza (ukukhetha ngokusekelwe esimweni esibi kakhulu)
2. Sebenzisa okungenani umkhawulo womklamo ongu-30% kusukela ku-torque eshicilelwe vs. i-speed curve (i-draw-out curve).
3. Qinisekisa ukuthi isicelo ngeke sivinjwe yimicimbi yangaphandle.
