Umgomo wokukhiqiza ukushisa wei-stepper motor.
1, imvamisa ukubona zonke izinhlobo zamamotho, ezangaphakathi ziyi-iron core kanye nekhoyili ejikajikayo.I-winging inokumelana, okunamandla kuzokhiqiza ukulahlekelwa, ubukhulu bokulahlekelwa bulingana nesikwele sokumelana nesimanje, okuvame ukubizwa ngokuthi ukulahlekelwa kwethusi, uma okwamanje kungeyona i-DC ejwayelekile noma i-sine wave, izophinde ikhiqize ukulahlekelwa kwe-harmonic; umgogodla unomphumela wamanje we-hysteresis eddy, endaweni eshintshanayo kazibuthe izophinde ikhiqize ukulahlekelwa, ubukhulu bayo kanye nezinto ezibonakalayo, zamanje, imvamisa, i-voltage, ebizwa ngokuthi ukulahlekelwa kwensimbi. Ukulahlekelwa kwethusi nokulahlekelwa kwensimbi kuzobonakala ngendlela yokushisa, ngaleyo ndlela kuthinte ukusebenza kahle kwemoto. Ama-Stepper motors ngokuvamile aphishekela ukunemba kokuma kanye nokuphuma kwe-torque, ukusebenza kahle kuphansi, okwamanje kuvamile, futhi izingxenye ezihambisanayo eziphezulu, imvamisa yokushintshashintsha kwamanje nayo iyahlukahluka ngesivinini, futhi ngenxa yalokho ama-stepper motors ngokuvamile anokushisa, futhi isimo sibi kakhulu kune-AC motor jikelele.
2, uhla olufanele lwei-stepper motorukushisa.
Ukushisa kwezimoto kuvunyelwe ukuthi kungakanani, ikakhulukazi kuncike ezingeni le-motor yangaphakathi lokufakwa. Ukusebenza kwe-insulation yangaphakathi emazingeni okushisa aphezulu (ama-130 degrees noma ngaphezulu) ngaphambi kokubhujiswa. Ngakho inqobo nje uma yangaphakathi ingeqi ama-degree angu-130, injini ngeke ilahlekelwe yindandatho, futhi izinga lokushisa elingaphezulu lizoba ngaphansi kwama-degree angu-90 ngalesi sikhathi.
Ngakho-ke, izinga lokushisa le-stepper motor surface ngama-70-80 degrees lijwayelekile. Indlela elula yokulinganisa izinga lokushisa ewusizo i-thermometer yephuzu, ungakwazi futhi ukunquma cishe: ngesandla singathinta imizuzwana engu-1-2, hhayi ngaphezu kwama-degree angu-60; ngesandla singathinta kuphela, cishe ama-70-80 degrees; amaconsi ambalwa amanzi ahwamuka ngokushesha, angaphezu kuka-90 degrees.
3, i-stepper motorukushisa ngezinguquko zejubane.
Uma usebenzisa ubuchwepheshe obuqhubekayo bedrayivu yamanje, ama-stepper motors ngesivinini esimile futhi esiphansi, yamanje izohlala ingashintshi ukuze kugcinwe ukuphuma kwe-torque njalo. Lapho ijubane liphakeme lifinyelela ezingeni elithile, amandla ekhawunta yangaphakathi yemoto ayakhuphuka, i-current izokwehla kancane kancane, futhi i-torque nayo izokwehla.
Ngakho-ke, isimo sokushisa ngenxa yokulahlekelwa kwethusi sizoxhomeka ngesivinini. Isivinini esiqinile nesiphansi ngokuvamile sikhiqiza ukushisa okuphezulu, kuyilapho isivinini esikhulu sikhiqiza ukushisa okuphansi. Kodwa ukulahlekelwa kwensimbi (nakuba ingxenye encane) izinguquko azifani, futhi imoto iyonke ukushisa kuyisamba salokhu okubili, ngakho-ke okungenhla kuyisimo esivamile kuphela.
4, umthelela wokushisa.
Nakuba ukushisa kwemoto ngokuvamile akuthinti ukuphila kwemoto, iningi lamakhasimende akudingeki likunake. Kodwa ngokungathí sina kuzoletha umthelela omubi. Njengama-coefficients ahlukene okwanda okushisayo kwezingxenye zangaphakathi ze-motor eziholela ekushintsheni kokucindezeleka kwesakhiwo kanye nezinguquko ezincane emgodini womoya wangaphakathi, kuzothinta impendulo eguquguqukayo yemoto, isivinini esikhulu kuyoba lula ukulahlekelwa isinyathelo. Esinye isibonelo ukuthi ezinye izikhathi azikuvumeli ukushisa okweqile kwemoto, njengemishini yezokwelapha kanye nemishini yokuhlola enembile, njll. Ngakho-ke, ukushisa kwemoto kufanele kudingeke ukulawula.
5, indlela yokunciphisa ukushisa kwenjini.
Ukunciphisa isizukulwane sokushisa, ukunciphisa ukulahlekelwa kwethusi nokulahlekelwa kwensimbi. Nciphisa ukulahlekelwa kwethusi ngezindlela ezimbili, ukunciphisa ukumelana namanje, okudinga ukukhethwa kokumelana okuncane kanye nokulinganisa okwamanje kwe-motor ngangokunokwenzeka, i-motor yesigaba ezimbili, i-motor ingasetshenziswa ochungechungeni ngaphandle kwe-parallel motor. Kodwa lokhu kuvame ukuphikisana nezidingo ze-torque nesivinini esikhulu. Enjinini ekhethiwe, umsebenzi wokulawula uhhafu wedrayivu ozenzakalelayo kanye nokusebenza okungaxhunyiwe ku-inthanethi kufanele kusetshenziswe ngokugcwele, eyokuqala inciphisa ngokuzenzakalelayo yamanje lapho injini iphumule, bese eyakamuva imane inqamule yamanje.
Ngaphezu kwalokho, idrayivu yokuhlukanisa, ngoba i-waveform yamanje iseduze ne-sinusoidal, i-harmonics encane, ukushisa kwemoto nakho kuzoba kuncane. Kunezindlela ezimbalwa zokunciphisa ukulahleka kwensimbi, futhi izinga le-voltage lihlobene nalo. Nakuba i-motor eqhutshwa amandla kagesi aphezulu izoletha ukwanda kwezici zesivinini esikhulu, futhi iletha ukwanda kokukhiqizwa kokushisa. Ngakho-ke kufanele sikhethe izinga elifanele le-voltage yokushayela, sicabangela isivinini esikhulu, ukushelela nokushisa, umsindo nezinye izinkomba.
Amasu okulawula okusheshisa kanye nezinqubo zokunciphisa ama-motor stepper.
Ngokusetshenziswa kabanzi kwama-motor stepper, isifundo sokulawulwa kwe-stepper motor siyakhula, ekuqaleni noma ukusheshisa uma i-stepper pulse ishintsha ngokushesha kakhulu, i-rotor ngenxa ye-inertia futhi ingalandeli izinguquko zesignali kagesi, okuholela ekuvimbeni noma ekulahlekeni kwesinyathelo ekumiseni noma ekunciphiseni ngenxa yesizathu esifanayo kungase kukhiqize ukweqa. Ukuze uvimbele ukuvinjwa, ukulahleka kwesinyathelo kanye ne-overshoot, ngcono imvamisa yokusebenza, i-stepper motor ukuphakamisa isilawuli sejubane.
Isivinini se-stepper motor sincike kubuningi be-pulse, inani lamazinyo e-rotor kanye nenani lokushaywa. Ijubane layo elingu-angular lilingana nemvamisa yokushaya kwenhliziyo futhi livumelaniswa ngesikhathi neshayela. Ngakho-ke, uma inani lamazinyo e-rotor kanye nenani lama-beats agijimayo liqinisekile, isivinini esifunayo singatholakala ngokulawula imvamisa ye-pulse. Njengoba i-stepper motor iqalwa ngosizo lwe-torque yayo ehambisanayo, imvamisa yokuqala ayiphezulu ukuze ungalahlekelwa isinyathelo. Ikakhulukazi njengoba amandla ekhula, ububanzi be-rotor buyanda, i-inertia iyanda, futhi imvamisa yokuqala kanye nemvamisa yokugijima ephezulu ingase ihluke izikhathi eziyishumi.
Izici zokuqala zemvamisa ye-stepper motor ukuze i-stepper motor iqale ingakwazi ukufinyelela ngqo imvamisa yokusebenza, kodwa ibe nenqubo yokuqalisa, okungukuthi, isuka ngesivinini esiphansi kancane kancane ikhuphuke ifinyelele isivinini sokusebenza. Misa lapho i-frequency yokusebenza ingeke yehliswe ngokushesha ibe yiziro, kodwa ibe nokwehliswa kwesivinini esinesivinini esikhulu kancane kancane sibe yinqubo enguziro.
I-torque ephumayo ye-stepper motor iyancipha ngokukhuphuka kwemvamisa ye-pulse, imvamisa yokuqala ikhuphuka, i-torque yokuqala incane, ikhono eliphansi lokushayela umthwalo, ukuqala kuzodala ukulahleka kwesinyathelo, futhi esitobhini kuzokwenzeka lapho i-overshoot. Ukwenza i-stepper motor ifinyelele ngokushesha isivinini esidingekayo futhi ingalahlekelwa isinyathelo noma i-overshoot, isihluthulelo siwukwenza inqubo yokusheshisa, i-torque yokusheshisa edingekayo ukuze usebenzise ngokugcwele i-torque ehlinzekwa yi-stepper motor ku-frequency ngayinye yokusebenza, futhi ungadluli le torque. Ngakho-ke, ukusebenza kwe-stepper motor ngokuvamile kufanele kudlule ukusheshisa, isivinini esifanayo, ukwehla kwezinyathelo ezintathu, ukusheshisa kanye nesikhathi senqubo yokunciphisa sibe sifushane ngangokunokwenzeka, isikhathi sesivinini esingaguquki eside ngangokunokwenzeka. Ikakhulukazi emsebenzini odinga impendulo esheshayo, kusukela ekuqaleni kuze kube sekupheleni kwesikhathi sokugijima esidingekayo ukuze sibe mfushane kakhulu, okumele kudinge ukusheshisa, inqubo yokunciphisa ijubane iyona emfushane kakhulu, kuyilapho isivinini esiphezulu kakhulu ngesivinini esingaguquki.
Ososayensi nochwepheshe ekhaya nasemazweni angaphandle benze ucwaningo oluningi ngobuchwepheshe bokulawula isivinini sama-stepper motors, futhi basungula izinhlobo zezibalo zokulawula ukusheshisa nokunciphisa ukwehla, njengemodeli ye-exponential, imodeli yomugqa, njll. izici zemvelo zemvamisa ye-stepper motors, zombili zokuqinisekisa ukuthi i-stepper motor inyakaza ngaphandle kokulahlekelwa isinyathelo, kodwa futhi inikeze ukudlala okugcwele ezicini zemvelo zemoto, ifinyeze isikhathi sejubane lokuphakamisa, kodwa ngenxa yezinguquko kumthwalo wemoto, kunzima ukufeza ngenkathi ukusheshisa okuqondile kanye nokwehla kwejubane kucabangela kuphela i-motor in the range umthamo we-angular velocity kanye ne-angular velocity kanye ne-voltage yokuhlinzeka ngenxa yalokhu kuphazamiseka kwe-voltage. kanye nezici zoshintsho, le ndlela yokusheshisa ukusheshisa ihlala njalo, ukonakala ukuthi ayicabangi ngokugcwele i-torque ye-stepper motor Enezici zokushintsha isivinini, i-stepper motor ngesivinini esikhulu izokwenzeka ngaphandle kwesinyathelo.
Lesi yisingeniso sesimiso sokushisa kanye nobuchwepheshe bokulawula inqubo yokusheshisa/yokwehlisa ama-stepper motors.
