Injini ye-stepperisimiso sokusebenza
Ngokuvamile, i-rotor yemoto iyimagnethi ehlala njalo. Uma ugesi ugeleza ngokugoqa i-stator, ukugoqa i-stator kukhiqiza insimu yamagnetic ye-vector. Le nsimu yamagnetic iqhuba i-rotor ukuthi ijikeleze nge-engela ukuze isiqondiso sezinkundla zamagnetic ze-rotor ezimbili sihambisane nensimu ye-stator. Lapho insimu yamagnetic ye-vector ye-stator ijikeleza nge-engela.
Injini ye-stepperuhlobo lwenjini yokungenisa, isimiso sayo sokusebenza ukusetshenziswa kwesekethe kagesi, ugesi oqondile ungene kugesi okwabelana ngesikhathi, ugesi wokulawula isikhathi wezigaba eziningi, ngalo mshini wokunikeza amandla wenjini ye-stepper, imoto ye-stepper ingasebenza kahle, umshayeli ungowokunikezwa kwamandla okwabelana ngesikhathi kwenjini ye-stepper, umlawuli wesikhathi wezigaba eziningi.
Ngayinye ifaka i-pulse kagesi, injini ijikeleza i-engeli phambili isinyathelo esisodwa. Ukukhishwa kwayo kwe-angular displacement kuhambelana nenani lama-pulse okufakwayo, isivinini sihambisana nemvamisa ye-pulse. Shintsha i-oda lokufaka amandla okugoqa, imoto izobuyela emuva. Ngakho-ke ungalawula inani lama-pulse, imvamisa kanye ne-oda lokunika amandla isigaba ngasinye se-motor winding ukulawula ukujikeleza kwe-stepper motor.
Ukunemba kwenjini ye-stepper evamile kungu-3-5% we-engeli ye-stepper, futhi ayiqongeleli.
I-torque yemoto ye-stepper izokwehla njengoba ijubane likhuphuka. Njengoba imoto ye-stepper ijikeleza, ukuhanjiswa kwesigaba ngasinye sokugoqa kwemoto kuzokwakha amandla kagesi abuyela emuva; lapho imvamisa iphakama, amandla kagesi abuyela emuva ayanda. Ngaphansi kwesenzo sayo, imoto enemvamisa (noma isivinini) iyanda futhi ugesi wesigaba uyancipha, okuholela ekwehleni kwe-torque.
Injini ye-Stepper ingasebenza ngokujwayelekile ngesivinini esiphansi, kodwa uma iphakeme kunesivinini esithile ngeke iqale, futhi ihambisane nomsindo wokushaya ikhwela.
Imoto ye-Stepper inepharamitha yobuchwepheshe: imvamisa yokuqala engenamthwalo, okungukuthi, imoto ye-stepper uma kwenzeka imvamisa yokushaya engenamthwalo ingaqalwa ngokujwayelekile, uma imvamisa yokushaya iphezulu kunenani, imoto ayikwazi ukuqala ngokujwayelekile, ingahle ivele ngaphandle kwesinyathelo noma ivimbe.
Uma kwenzeka umthwalo, imvamisa yokuqala kufanele ibe phansi. Uma injini izokwenza ukujikeleza kwesivinini esikhulu, imvamisa yokushaya kwenhliziyo kufanele ibe nenqubo yokusheshisa, okungukuthi, imvamisa yokuqala iphansi, bese ikhuphukela kumvamisa ephezulu oyifunayo (isivinini senjini sisuka esivinini esiphansi siye esivinini esikhulu) ngokusheshisa okuthile.
Kunganiama-stepper motorskudingeka kulawulwe ngokunciphisa isivinini
Ijubane lemoto ye-stepper lincike ku-pulse frequency, inani lamazinyo e-rotor kanye nenani lama-beats. Ijubane layo le-angular lihambisana ne-pulse frequency futhi livumelaniswa ngesikhathi ne-pulse. Ngakho-ke, uma inani lamazinyo e-rotor kanye nenani lama-beats asebenzayo liqinisekile, ijubane elifunekayo lingatholakala ngokulawula i-pulse frequency. Njengoba imoto ye-stepper iqalwa ngosizo lwe-synchronous torque yayo, i-start frequency ayiphezulu ukuze ingalahlekelwa yisinyathelo. Ikakhulukazi njengoba amandla ekhuphuka, ububanzi be-rotor buyanda, i-inertia iyanda, futhi i-start frequency kanye ne-high running frequency ingahluka ngokuphindwe kayishumi.
Izici zemvamisa yokuqala yemoto ye-stepper ukuze isiqalo semoto ye-stepper singafinyeleli ngqo imvamisa yokusebenza, kodwa sibe nenqubo yokuqalisa, okungukuthi, kusukela esivinini esiphansi kancane kancane sikhuphukela esivinini sokusebenza. Yeka lapho imvamisa yokusebenza ingeke yehle ngokushesha iye ku-zero, kodwa ibe nokunciphisa isivinini kancane kancane iye enqubweni ye-zero.
Ngakho-ke, ukusebenza kwemoto ye-stepper ngokuvamile kufanele kudlule ekusheshiseni, isivinini esifanayo, ukwehlisa ijubane ngezigaba ezintathu, inqubo yokusheshisa nokwehlisa ijubane ibe mfushane ngangokunokwenzeka, isikhathi sejubane esingaguquki sibe side ngangokunokwenzeka. Ikakhulukazi emsebenzini odinga impendulo esheshayo, isikhathi esidingekayo ukuze siqale kusukela ekuqaleni kuze kube sekupheleni yisona esifushane kakhulu, okumele sidinge inqubo emfushane kakhulu yokusheshisa nokwehlisa ijubane, kanye nesivinini esiphezulu kakhulu ngesivinini esingaguquki.
I-algorithm yokusheshisa nokwehlisa ijubane ingenye yezindlela zobuchwepheshe ezibalulekile ekulawuleni ukunyakaza, futhi ingenye yezinto ezibalulekile zokufeza isivinini esikhulu kanye nokusebenza kahle okuphezulu. Ekulawuleni kwezimboni, ngakolunye uhlangothi, inqubo yokucubungula iyadingeka ukuthi ibe bushelelezi futhi izinzile, ibe nomthelela omncane wokuguquguquka; ngakolunye uhlangothi, idinga isikhathi sokuphendula okusheshayo kanye nokusabela okusheshayo. Esimweni sokuqinisekisa ukunemba kokulawula ukuthuthukisa ukusebenza kahle kokucubungula, ukuze kufezwe ukunyakaza okubushelelezi nokuzinzile kwemishini, ukucubungula kwamanje kwezimboni kube ukuxazulula inkinga ebalulekile. Ama-algorithm okusheshisa nokwehlisa ijubane avame ukusetshenziswa ezinhlelweni zokulawula ukunyakaza kwamanje afaka phakathi: ukusheshisa nokunciphisa ijika le-trapezoidal, ukusheshisa nokunciphisa ijika le-exponential, ukusheshisa nokunciphisa ijika elinomumo we-S, ukusheshisa nokunciphisa ijika le-parabolic, njll.
Ukusheshisa kanye nokwehla kwejika le-Trapezoidal
Incazelo: Ukusheshisa/ukwehlisa ijubane ngendlela eqondile (ukusheshisa/ukwehlisa ijubane kusukela esivinini sokuqala kuya esivinini esiqondiwe) ngesilinganiso esithile
Ifomula yokubala: v(t)=Vo+at
Izinzuzo nokungalungi: Ijika le-Trapezoidal libonakala nge-algorithm elula, ethatha isikhathi esincane, impendulo esheshayo, ukusebenza kahle okuphezulu kanye nokusetshenziswa okulula. Kodwa-ke, izigaba zokusheshisa kanye nokwehlisa ijubane ezifanayo azihambisani nomthetho wokushintsha isivinini se-stepper motor, futhi iphuzu lokushintsha phakathi kwesivinini esiguquguqukayo kanye nesivinini esifanayo alikwazi ukuba bushelelezi. Ngakho-ke, le algorithm isetshenziswa kakhulu ezinhlelweni zokusebenza lapho izidingo zenqubo yokusheshisa kanye nokwehlisa ijubane zingekho phezulu.
Ukusheshisa kwejika le-Exponential kanye nokwehla kwejubane
Incazelo: Kusho ukusheshisa kanye nokwehla kwejubane ngomsebenzi we-exponential.
Ukusheshisa kanye nokunciphisa izinga lokulawula ukuhlolwa kwenkomba:
1. Iphutha lomzila womshini kanye nesikhundla kufanele libe lincane ngangokunokwenzeka
2. Inqubo yokunyakaza komshini ibushelelezi, ukujiya kuncane, futhi impendulo ishesha
3, i-algorithm yokusheshisa kanye nokwehlisa ijubane kufanele ibe lula ngangokunokwenzeka, kube lula ukuyisebenzisa, futhi ingahlangabezana nezidingo zokulawula zesikhathi sangempela
