Njengento yokusebenza kwedijithali, i-stepper motor isetshenziswa kabanzi ohlelweni lokulawula ukunyakaza. Abasebenzisi abaningi nabangane ekusebenziseni ama-stepper motors, banomuzwa wokuthi i-stepper motor isebenza ngokushisa okukhulu, inhliziyo iyangabaza, abazi ukuthi lesi simo sijwayelekile yini. Eqinisweni, ukushisa kuyinto evamile yama-stepper motors, kodwa yiliphi izinga lokushisa elibhekwa njengelijwayelekile, nokuthi unganciphisa kanjani ukushisa kwe-stepper motor?
Ukuze uqonde ukuthi kungani injini ye-stepper izoshisa.
Kuzo zonke izinhlobo zama-stepper motors, ingaphakathi lakhiwe nge-iron core kanye ne-winding coil. Ukumelana nokugoba, amandla kuzokhiqiza ukulahlekelwa, usayizi wokulahlekelwa kanye nokumelana kanye nomsinga kuyalingana nesikwele, yilokhu esivame ukukubiza ngokuthi ukulahlekelwa kwethusi, uma umsinga ungeyona i-DC ejwayelekile noma i-sine wave, kuzokhiqiza nokulahlekelwa kwe-harmonic; umphumela wamanje we-core hysteresis eddy, ensimini yamagnetic eshintshanayo kuzokhiqiza nokulahlekelwa, usayizi wezinto ezibonakalayo, umsinga, imvamisa, okuhlobene ne-voltage, okubizwa ngokuthi ukulahlekelwa kwensimbi. Ukulahleka kwethusi kanye nokulahlekelwa kwensimbi kuzobonakala ngesimo sokukhiqiza ukushisa, ngaleyo ndlela kuthinte ukusebenza kahle kwemoto.
Injini yokwenyuka ngokuvamile iphishekela ukunemba kokubeka kanye nokukhipha i-torque, ukusebenza kahle kuphansi, ugesi ngokuvamile mkhulu, kanye nezingxenye eziphezulu ze-harmonic, imvamisa yamandla kagesi ishintshana ngesivinini kanye noshintsho, ngakho-ke ama-stepping motor ngokuvamile anesimo sokushisa, futhi isimo sibi kakhulu kunenjini ejwayelekile ye-AC.
Futhi, ukulawula ukushisa kwe-stepper motor ngaphakathi kobubanzi obufanele.
Ukushisa kwemoto okuvunyelwe ngezinga elingakanani, kuncike kakhulu ezingeni lokufakwa kwemoto ngaphakathi. Ukufakwa kwemoto ngaphakathi akubhujiswa kuze kube yilapho sekusezingeni lokushisa eliphezulu (ngaphezu kwama-degrees angu-130). Ngakho-ke uma nje okwangaphakathi kungadluli ama-degrees angu-130, imoto ngeke yonakale, bese izinga lokushisa lobuso lizoba ngaphansi kwama-degrees angu-90. Ngakho-ke, izinga lokushisa lobuso bemoto ye-stepper lama-degrees angu-70-80 livamile. Indlela elula yokulinganisa izinga lokushisa nge-thermometer, ungahlulela futhi ngokucophelela: ngesandla singathinta imizuzwana engaphezu kwe-1-2, hhayi ngaphezu kwama-degrees angu-60; ngesandla singathinteka kuphela, cishe ama-degrees angu-70-80; amaconsi ambalwa amanzi aphenduka ngokushesha, angaphezu kwama-degrees angu-90; vele, ungasebenzisa nesibhamu sokushisa ukuthola.
Ngaphezu kwalokho, i-stepper motor efudumeza ngokushintsha kwesivinini.
Uma usebenzisa ubuchwepheshe bokushayela bamanje obuqhubekayo, i-stepper motor ngesivinini esingaguquki nesiphansi, ugesi uzohlala ungaguquki ukuze ugcine ukukhishwa kwe-torque okungaguquki.
Uma ijubane liphezulu ngezinga elithile, amandla angemuva ngaphakathi kwenjini ayakhuphuka, amandla kagesi azoncipha kancane kancane, futhi i-torque nayo izoncipha. Ngakho-ke, ukukhiqizwa kokushisa ngenxa yokulahlekelwa yithusi kuhlobene nejubane.
Ukukhiqizwa kokushisa ngokuvamile kuphezulu ngesivinini esingaguquki nesiphansi futhi kuphansi ngesivinini esiphezulu. Kodwa ukushintsha kokulahlekelwa yinsimbi (nakuba kuyisilinganiso esincane) akunjalo, futhi ukushisa kwenjini yonke kuyisamba salokhu okubili, ngakho-ke okungenhla kumane kuyisimo esijwayelekile.
Umthelela wokushisa
Ukushisa kwenjini, nakuba ngokuvamile kungathinti impilo yenjini, amakhasimende amaningi akudingeki aqaphele. Kodwa-ke, ukushisa okukhulu kuzoletha imiphumela emibi.
Njengezingxenye zangaphakathi ze-coefficient yokwanda kokushisa kwemoto yokucindezeleka okuhlukahlukene kwesakhiwo okubangelwa izinguquko kugebe lomoya wangaphakathi kanye nezinguquko ezincane zizothinta impendulo enamandla yemoto, isivinini esikhulu sizoba lula ukulahlekelwa yisinyathelo.
Esinye isibonelo ukuthi ezinye izikhathi azivumeli ukushisa ngokweqile kwenjini, njengemishini yezokwelapha kanye nemishini yokuhlola enembile kakhulu. Ngakho-ke, ukushisa kwenjini kufanele kube ukulawula okudingekayo.
五、 nciphisa ukushisa kwemoto.
Nciphisa ukushisa, ukunciphisa ukulahlekelwa kwethusi nokulahlekelwa yinsimbi. Nciphisa ukulahlekelwa kwethusi kunezindlela ezimbili, ukunciphisa ukumelana kanye nokwamanje, okudinga ukukhethwa kokumelana okuncane kanye nokwamanje okulinganiselwe ngangokunokwenzeka ekukhetheni izinjini ezincane, izinjini zesigaba ezimbili, ezingasetshenziswa ochungechungeni lwezinjini akudingeki zihambisane nezinjini.
Kodwa lokhu kuvame ukungqubuzana nezidingo ze-torque kanye nesivinini esikhulu.
Njengoba injini isikhethiwe, kufanele isebenzise ngokugcwele umsebenzi wokulawula we-half-current othomathikhi wedrayivu kanye nomsebenzi ongaxhunyiwe ku-inthanethi, owokuqala wehlisa ngokuzenzakalelayo ugesi uma imoto isesimweni esingaguquki, owokugcina umane unqamule ugesi.
Ngaphezu kwalokho, idrayivu ehlukaniswe kahle ngenxa yesimo segagasi lamanje esiseduze ne-sinusoidal, ama-harmonics amancane, ukushisa kwenjini kuzoba kuncane. Azikho izindlela eziningi zokunciphisa ukulahleka kwensimbi, izinga le-voltage lihlobene ne-motor yedrayivu ye-voltage ephezulu, yize izoletha izici zesivinini esikhulu sokuthuthukiswa, kodwa futhi ilethe ukwanda kokushisa.
Ngakho-ke, kufanele sikhethe izinga elifanele le-drive voltage, sicabangela isivinini esiphezulu, ukushelela nokushisa, umsindo nezinye izinkomba.
