Umthetho osesandleni sobunxele, umthetho wesandla sokudla, umthetho wesikulufa sesandla sokudla.Umthetho ongakwesokunxele, lokhu kuyisisekelo sokuhlaziywa kwamandla okujikeleza kwemoto.Kalula nje, yi-conductor ephethe njengamanje endaweni kazibuthe, ezothintwa amandla.

Vumela umugqa we-magnetic field udlule phambi kwesandla, isiqondiso seminwe isiqondiso se-current, futhi isiqondiso sesithupha isiqondiso samandla kazibuthe.Ukudonswa kwamandla kunqamula imigqa yakazibuthe ukuze kukhiqizwe amandla e-electromotive.

Vumela umugqa wamagnetic udlule entendeni yesandla, isiqondiso sesithupha isiqondiso sokunyakaza, futhi isiqondiso somunwe isiqondiso samandla e-electromotive akhiqizwayo.Kungani ukhuluma nge-electromotive force eyenziwe?Angazi noma unakho yini isipiliyoni esifanayo.Uma uhlanganisa izintambo zezigaba ezintathu ze-motor bese uvula imoto ngesandla, uzothola ukuthi ukumelana kukhulu kakhulu.Lokhu kungenxa yokuthi ukungeniswa kwenzeka ngesikhathi sokujikeleza kwemoto.Amandla e-electromotive akhiqiza amandla amanje, futhi amandla amanje ageleza ku-conductor endaweni kazibuthe azokhiqiza amandla aphikisana nesiqondiso sokujikeleza, futhi wonke umuntu uzozwa ukuthi kunokuningi ukumelana nokujikeleza.

Izintambo ezinezigaba ezintathu zihlukene futhi injini ingaphendulwa kalula

Imigqa yezigaba ezintathu ihlangene, futhi ukumelana kwemoto kukhulu kakhulu.Ngokomthetho wesikulufu esisesandleni sokudla, bamba i-solenoid enikwe amandla ngesandla sokudla, ukuze iminwe emine igobe iqonde endaweni yamanje, bese isiphetho esikhonjwe ngesithupha isigxobo esingu-N se-solenoid enikwe amandla.

Lo mthetho uyisisekelo sokwahlulela i-polarity yekhoyili enamandla, futhi isiqondiso somcibisholo obomvu isiqondiso samanje.Ngemva kokufunda le mithetho emithathu, ake sibheke izimiso eziyisisekelo zokujikeleza kwezimoto.Ingxenye yokuqala: Imodeli yemoto ye-DC Sithola imodeli yemoto ye-DC eye yafundwa esikoleni samabanga aphezulu, futhi senza ukuhlaziya okulula ngokusebenzisa indlela yokuhlaziya isekethe kazibuthe.

Isimo 1 Uma i-current isetshenziswa kumakhoyili kuzo zombili iziphetho, ngokomthetho wesikulufu sangakwesokudla, amandla okungenisa kazibuthe asetshenziswayo asetshenziswayo B (njengoba kuboniswa umcibisholo owugqinsi) azokwenziwa, futhi i-rotor emaphakathi izozama ukwenza. isiqondiso somugqa wokungenisa kazibuthe wangaphakathi ngangokunokwenzeka.Ukuqondiswa komugqa wangaphandle kazibuthe kuyavumelana ukwenza iluphu yomugqa wensimu kazibuthe evaliwe, ukuze i-rotor engaphakathi izozungezisa ngokwewashi.Lapho isiqondiso se-rotor magnetic field sibhekene nesiqondiso sensimu yamagnetic yangaphandle, i-torque ejikelezayo ye-rotor inkulu kakhulu.Qaphela ukuthi “umzuzu” kuthiwa mkhulu, hhayi “amandla”.Kuyiqiniso ukuthi uma i-rotor magnetic field isendleleni efanayo ne-magnetic field yangaphandle, amandla kazibuthe ku-rotor inkulu, kodwa ngalesi sikhathi i-rotor isesimweni esivundlile futhi ingalo yamandla ingu-0, futhi vele ngeke ijikele.Ukwengeza, isikhathi siwumkhiqizo wamandla kanye nengalo yamandla.Uma enye yazo inguziro, umkhiqizo unguziro.Lapho i-rotor iphendukela endaweni evundlile, nakuba ingasathinteki i-torque ejikelezayo, izoqhubeka nokujikeleza ngokwewashi ngenxa ye-inertia.Ngalesi sikhathi, uma isiqondiso samanje se-solenoid ezimbili sishintshiwe, njengoba kuboniswe esithombeni esingezansi, i-rotor izoqhubeka nokujikeleza.jikela phambili ngokwewashi,

Esimweni sesi-2, isiqondiso samanje se-solenoids emibili sishintsha njalo, futhi i-rotor yangaphakathi izoqhubeka nokujikeleza.Lesi senzo sokushintsha isiqondiso se-current sibizwa ngokuthi ukuhamba.Inothi eseceleni: Ukuhamba nini kuhlobene kuphela nendawo yerotha futhi akuhlobene ngokuqondile nanoma yibuphi obunye ubuningi.Ingxenye 2: Injini yerotha yangaphakathi yezigaba ezintathu enezigxobo ezimbili Ngokuvamile, amawindi esigaba sesithathu se-stator anemodi yokuxhuma inkanyezi kanye nemodi yokuxhuma i-delta, futhi "imodi yokuqhuba ezimbili-ezimbili yoxhumano lwezinkanyezi ezintathu" iyona evame kakhulu. esetshenzisiwe, esetshenziswa lapha.Le modeli isetshenziselwa ukuhlaziya okulula.

Isibalo esingenhla sibonisa ukuthi i-stator windings ixhunywe kanjani (i-rotor ayiboniswa njenge-hypothetical uzibuthe wezigxobo ezimbili), futhi ama-windings amathathu axhunywe ndawonye ngesimo esithi "Y" ngokusebenzisa indawo yokuxhuma emaphakathi.Imoto yonke iholela ezintanjeni ezintathu A, B, C. Uma zinikwa amandla ngambili ngababili, kukhona amakesi ayi-6, okuyi-AB, AC, BC, BA, CA, CB.Qaphela ukuthi lokhu kuhlelekile.

Manje ngibheka isigaba sokuqala: Isigaba sika-AB sinomfutho

Lapho isigaba se-AB sinikezwa amandla, isiqondiso somugqa wensimu kazibuthe okhiqizwe ikhoyili yesigxobo esiboniswa umcibisholo obomvu, futhi isiqondiso somugqa wenkundla kazibuthe okhiqizwe isigxobo esingu-B siboniswa umcibisholo oluhlaza okwesibhakabhaka, bese isiqondiso amandla angumphumela aboniswa umcibisholo oluhlaza, bese Ngokucabanga ukuthi kukhona uzibuthe onezigxobo ezimbili, isiqondiso se-N-pole sizoqondana nesiqondiso esiboniswa umcibisholo oluhlaza ngokusho "i-rotor phakathi izozama ukugcina isiqondiso semigqa yayo yangaphakathi yakazibuthe ehambisana nesiqondiso semigqa yangaphandle kazibuthe”.Mayelana no-C, akahlanganise lutho naye okwamanje.

Isigaba 2: Isigaba se-AC Sinikwe Amandla

Isigaba sesithathu: BC isigaba sokufakwa kukagesi

Isigaba sesithathu: Isigaba se-BA sinikwe amandla

Okulandelayo umdwebo wesimo sikazibuthe ophakathi (irotha):Irotha yenqubo ngayinye izungeza amadigri angama-60

Ukuzungezisa okuphelele kuphothulwa ezinqubweni eziyisithupha, lapho kwenziwa izinguquko eziyisithupha.Ingxenye yesithathu: isigaba sesithathu esinama-multi-pole multi-pole inner rotor motor Ake sibheke iphuzu eliyinkimbinkimbi.Umfanekiso (a) uyinjini yesigaba sesishiyagalolunye enamawindi ayisithupha (isigaba sesithathu, esinamawindi ayisishiyagalolunye, esinamapali ayisithupha).Isigxobo esiphambene) i-rotor motor yangaphakathi, uxhumano lwayo olumazombezombe luboniswa kumfanekiso (b).Kungabonakala kuMfanekiso (b) ukuthi ama-windings ezigaba ezintathu nawo axhunywe ndawonye endaweni ephakathi, okubuye kube uxhumano lwenkanyezi.Ngokuvamile, inani lama-winding enjini alihambisani nenani lezigxobo zikazibuthe ezihlala njalo (isibonelo, ama-windings angu-9 nezigxobo ezingu-6 zisetshenziswa esikhundleni sama-windings angu-6 nezigxobo ezingu-6), ukuze kuvinjelwe amazinyo e-stator kanye ozibuthe be-rotor ekukhangeni nasekuqondaniseni.

Umgomo wokunyakaza kwayo uthi: I-N pole ye-rotor kanye ne-S pole yokujika okunamandla inomkhuba wokuqondanisa, futhi i-S pole ye-rotor kanye ne-N pole yokujika okunamandla inomkhuba wokuqondanisa.Okusho ukuthi, u-S no-N badonsana.Qaphela ukuthi ihlukile endleleni yokuhlaziya yangaphambilini.Hhayi-ke, asikusize ukuthi uyihlaziye futhi.Isigaba sokuqala: Isigaba sika-AB sifakwa ugesi

Isigaba 2: Isigaba se-AC Sinikwe Amandla

Isigaba sesithathu: BC isigaba sokufakwa kukagesi
