Isimiso sokukhiqiza ukushisainjini ye-stepper.
1, ngokuvamile ubona zonke izinhlobo zama-motor, angaphakathi aqukethe i-iron core kanye ne-winding coil.Ukugoqa kunokumelana, amandla azokhiqiza ukulahlekelwa, ubukhulu bokulahlekelwa buhambisana nesikwele sokumelana kanye nogesi, okuvame ukubizwa ngokuthi ukulahlekelwa kwethusi, uma ugesi ungeyona i-DC ejwayelekile noma i-sine wave, uzokhiqiza nokulahlekelwa kwe-harmonic; i-core ine-hysteresis eddy current effect, ensimini yamagnetic eshintshanayo izokhiqiza nokulahlekelwa, usayizi wayo nezinto zayo, ugesi, imvamisa, i-voltage, okubizwa ngokuthi ukulahlekelwa kwensimbi. Ukulahlekelwa kwethusi kanye nokulahlekelwa kwensimbi kuzobonakala ngesimo sokushisa, ngaleyo ndlela kuthinte ukusebenza kahle kwemoto. Ama-Stepper motors ngokuvamile aphishekela ukunemba kokubeka kanye nokukhishwa kwe-torque, ukusebenza kahle kuphansi, ugesi ngokuvamile mkhulu, kanye nezingxenye eziphezulu ze-harmonic, imvamisa yokushintshana kwamanje nayo iyahlukahluka ngesivinini, futhi ngaleyo ndlela ama-stepper motors ngokuvamile anokushisa, futhi isimo sibi kakhulu kunemoto ejwayelekile ye-AC.
2, ububanzi obufaneleinjini ye-stepperukushisa.
Ukushisa kwemoto okuvunyelwe ngezinga elingakanani, kuncike kakhulu ezingeni lokufakwa kwemoto ngaphakathi. Ukusebenza kokufakwa kwemoto ngaphakathi emazingeni okushisa aphezulu (ama-degrees angu-130 noma ngaphezulu) ngaphambi kokubhujiswa. Ngakho-ke uma nje okwangaphakathi kungadluli ama-degrees angu-130, imoto ngeke ilahlekelwe yindandatho, futhi izinga lokushisa lobuso lizoba ngaphansi kwama-degrees angu-90 ngalesi sikhathi.
Ngakho-ke, izinga lokushisa lobuso be-stepper motor ngama-degree angu-70-80 livamile. Indlela elula yokulinganisa izinga lokushisa ewusizo, unganquma futhi: ungathinta imizuzwana engaphezu kwe-1-2 ngesandla, hhayi ngaphezu kwama-degree angu-60; ungathinta kuphela ngesandla, cishe ama-degree angu-70-80; amaconsi ambalwa amanzi aphenduka ngokushesha abe ngumswakama, angaphezu kwama-degree angu-90.
3, injini ye-stepperukushisa ngezinguquko zesivinini.
Uma usebenzisa ubuchwepheshe bokushayela bamanje obuqhubekayo, ama-stepper motors ngesivinini esingaguquki nesiphansi, ugesi uzohlala ungaguquki ukuze kugcinwe ugesi ophumayo ongaguquki. Uma isivinini siphezulu sifinyelela ezingeni elithile, amandla angaphakathi enjini ayakhuphuka, ugesi uzokwehla kancane kancane, futhi ugesi uzokwehla.
Ngakho-ke, isimo sokushisa esibangelwa ukulahleka kwethusi sizoncika esivinini. Isivinini esingaguquki nesiphansi ngokuvamile sikhiqiza ukushisa okuphezulu, kuyilapho isivinini esikhulu sikhiqiza ukushisa okuphansi. Kodwa ukulahleka kwensimbi (nakuba kuyisilinganiso esincane) izinguquko azifani, futhi injini njengokushisa okuphelele iyisamba salokhu okubili, ngakho-ke okungenhla kuyisimo esijwayelekile kuphela.
4, umthelela wokushisa.
Nakuba ukushisa kwemoto ngokuvamile kungathinti impilo yemoto, iningi lamakhasimende akudingeki liyinake. Kodwa ngokungathi sína kuzoletha umthelela omubi. Njengezinhlanganisela ezahlukene zokwanda kokushisa kwezingxenye zangaphakathi zemoto kuholela ekushintsheni kokucindezeleka kwesakhiwo kanye nezinguquko ezincane esikhaleni somoya wangaphakathi, kuzothinta impendulo enamandla yemoto, isivinini esikhulu sizoba lula ukulahlekelwa yisinyathelo. Esinye isibonelo ukuthi ezinye izikhathi azivumeli ukushisa okweqile kwemoto, njengemishini yezokwelapha kanye nemishini yokuhlola enembile kakhulu, njll. Ngakho-ke, ukushisa kwemoto kufanele kudingeke ukuze kulawulwe.
5, indlela yokunciphisa ukushisa kwenjini.
Ukunciphisa ukukhiqizwa kokushisa, kunciphisa ukulahleka kwethusi kanye nokulahlekelwa yinsimbi. Ukunciphisa ukulahleka kwethusi ngezindlela ezimbili, kunciphisa ukumelana kanye nogesi, okudinga ukukhethwa kokumelana okuncane kanye nogesi olinganisiwe wemoto ngangokunokwenzeka, imoto enezigaba ezimbili, imoto ingasetshenziswa ochungechungeni ngaphandle kwemoto ehambisanayo. Kodwa lokhu kuvame ukungqubuzana nezidingo ze-torque kanye nesivinini esiphezulu. Kumoto ekhethiwe, umsebenzi wokulawula wesigamu-samandla okuzenzakalelayo wedrayivu kanye nomsebenzi ongaxhunyiwe ku-inthanethi kufanele kusetshenziswe ngokugcwele, owokuqala wehlisa ngokuzenzakalelayo ugesi lapho imoto iphumula, kanti owokugcina umane unqamule ugesi.
Ngaphezu kwalokho, idrayivu yokuhlukanisa, ngoba i-waveform yamanje iseduze ne-sinusoidal, ama-harmonics amancane, ukushisa kwemoto nakho kuzoba kuncane. Zimbalwa izindlela zokunciphisa ukulahleka kwensimbi, futhi izinga le-voltage lihlobene nalo. Nakuba injini eqhutshwa yi-voltage ephezulu izoletha ukwanda kwezici zesivinini esikhulu, futhi iletha ukwanda kokukhiqizwa kokushisa. Ngakho-ke kufanele sikhethe izinga le-voltage yedrayivu efanele, sicabangela isivinini esiphezulu, ukushelela nokushisa, umsindo nezinye izinkomba.
Amasu okulawula izinqubo zokusheshisa kanye nokunciphisa ijubane lama-stepper motors.
Njengoba ukusetshenziswa kabanzi kwama-stepper motors kuyanda, ucwaningo lokulawula ama-stepper motor luyanda, ekuqaleni noma ekusheshiseni uma i-stepper pulse ishintsha ngokushesha kakhulu, i-rotor ngenxa ye-inertia futhi ingalandeli izinguquko zesignali kagesi, okuholela ekuvinjweni noma ekulahlekelweni kwesinyathelo ekumisweni noma ekwehleni kwejubane ngesizathu esifanayo kungabangela ukweqa. Ukuze kuvinjelwe ukuvinjelwa, ukulahlekelwa kwesinyathelo kanye nokweqa ngokweqile, thuthukisa imvamisa yokusebenza, i-stepper motor iphakamisa ukulawula 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 yehliswe ngokushesha ibe yi-zero, kodwa ibe nokunciphisa isivinini kancane kancane kube yi-zero inqubo.
I-torque yokukhipha yemoto ye-stepper iyancipha ngokukhuphuka kwemvamisa yokushaya kwenhliziyo, lapho imvamisa yokuqala iphakama, i-torque yokuqala incane, ikhono lokushayela umthwalo liphansi, ukuqala kuzobangela ukulahlekelwa yisinyathelo, futhi ekumisweni kuzokwenzeka lapho kuqhuma kakhulu. Ukuze imoto ye-stepper ifinyelele ngokushesha isivinini esidingekayo futhi ingalahlekelwa yisinyathelo noma i-overshoot, isihluthulelo ukwenza inqubo yokusheshisa, i-torque yokusheshisa edingekayo ukuze isebenzise ngokugcwele i-torque enikezwa yimoto ye-stepper ku-frequency ngayinye yokusebenza, futhi ingadluli le torque. Ngakho-ke, ukusebenza kwemoto ye-stepper ngokuvamile kufanele kudlule ekusheshiseni, isivinini esifanayo, i-deceleration izigaba ezintathu, isikhathi senqubo yokusheshisa kanye ne-deceleration sibe sifushane ngangokunokwenzeka, isikhathi sesivinini esingaguquki sibe side ngangokunokwenzeka. Ikakhulukazi emsebenzini odinga impendulo esheshayo, kusukela ekuqaleni kuze kube sekupheleni kwesikhathi sokusebenza esidingekayo ukuze sibe sifushane kakhulu, okumele sidinge ukusheshisa, inqubo yokwehlisa ijubane iyona emfushane kakhulu, kuyilapho ijubane eliphakeme kakhulu ngesivinini esingaguquki.
Ososayensi nabachwepheshe basekhaya nakwamanye amazwe benze ucwaningo oluningi ngobuchwepheshe bokulawula isivinini sama-stepper motors, futhi basungula izinhlobo ezahlukene zamamodeli ezibalo zokulawula ukusheshisa nokwehlisa isivinini, njengemodeli ye-exponential, imodeli eqondile, njll., futhi ngokusekelwe kulolu klamo nokuthuthukiswa kwezifunda ezahlukene zokulawula ukuthuthukisa izici zokunyakaza kwama-stepper motors, ukukhuthaza ububanzi bokusetshenziswa kwama-stepper motors, ukusheshisa nokwehlisa isivinini kubheka izici zemvamisa yesikhashana zama-stepper motors, kokubili ukuqinisekisa ukuthi imoto ye-stepper iyaqhubeka ngaphandle kokulahlekelwa yisinyathelo, kodwa futhi inikeze ukudlala okugcwele ezicini zemoto, ifinyeze isikhathi sesivinini sokuphakamisa, kodwa ngenxa yezinguquko emthwalweni wemoto, kunzima ukufeza ngenkathi ukusheshisa nokwehlisa isivinini okuqondile kucabangela kuphela imoto ebangeni lomthamo womthwalo wejubane le-angular kanye ne-pulse elihambisana nalobu budlelwano, hhayi ngenxa yokuguquguquka kwe-voltage yokuphakelwa, indawo yomthwalo kanye nezici zoshintsho, le ndlela yokusheshisa ijubane ihlala njalo, ububi ukuthi ayicabangi ngokugcwele i-torque yokukhipha imoto ye-stepper. Ngezici zokushintsha kwesivinini, imoto ye-stepper ngesivinini esiphezulu izophuma ngaphandle kwesinyathelo.
Lesi isingeniso sesimiso sokushisa kanye nobuchwepheshe bokulawula inqubo yokusheshisa/yokunciphisa ijubane lama-stepper motors.
