Mutemo wekuruboshwe, mutemo wekurudyi, mutemo wekurudyi wekurudyi.Mutemo wekuruboshwe, iyi ndiyo nheyo yekuongororwa kwesimba rekutenderera kwemotokari.Zvichitaurwa zviri nyore, ndiyo ikozvino-inotakura kondakita mune magnetic field, iyo ichabatwa nesimba.

Rega mutsara wemagnetic field upfuure mberi kwechanza, kutungamirirwa kweminwe ndiyo nzira yezvino, uye kutungamira kwechigunwe ndiko kutungamirirwa kwesimba remagineti.Kudhonza kwesimba kunocheka mitsara yemagineti kugadzira simba remagetsi.

Rega mutsara wemagineti upfuure nemuchanza, kutungamira kwechigunwe ndiko kutungamira kwekufamba, uye kutungamira kwemunwe ndiyo kutungamira kweiyo yakagadzirwa electromotive simba.Sei uchitaura nezve induced electromotive force?Handizivi kana une chimwe chiitiko chakafanana.Paunosanganisa waya matatu-chikamu chemota uye uchitenderedza mota neruoko, uchaona kuti kushorwa kwakakura kwazvo.Izvi zvinodaro nekuti induction inoitika panguva yekutenderera kwemota.Simba re electromotive rinogadzira ikozvino, uye ikozvino inoyerera kuburikidza nekondukita mune magnetic field ichaita simba rakapesana nekutungamira kwekutenderera, uye munhu wese achanzwa kuti pane zvakawanda zvinopesana nekutenderera.

Iwo matatu-chikamu waya akapatsanurwa uye mota inogona kushandurwa nyore

Iyo mitsetse mitatu-yechikamu inosanganiswa, uye kushorwa kwemota kwakakura kwazvo.Maererano nemutemo wekurudyi wekurudyi, bata solenoid ine simba neruoko rwerudyi, kuitira kuti zvigunwe zvina zvigove zvakaenzana nezvino, zvino kuguma kunongedzerwa nechigunwe ndiyo N pole ye energized solenoid.

Mutemo uyu ndiwo hwaro hwekutonga polarity ye coil ine simba, uye kutungamira kwemuseve mutsvuku ndiyo nzira iripo.Mushure mokuverenga mitemo mitatu, ngatitarisei nheyo dzekutanga dzekufambisa motokari.Chikamu chekutanga: DC mota modhi Isu tinowana modhi yeDC mota yakadzidzwa muchikoro chepamusoro fizikisi, uye kuita ongororo yakapusa kuburikidza nemagineti yedunhu yekuongorora nzira.

State 1 Kana ikozvino yaiswa kumakoiri kumagumo ese ari maviri, zvinoenderana nerudyi-kurudyi screw mutemo, inoiswa magineti induction intensity B (sezvinoratidzwa nemuseve wakakora) ichagadzirwa, uye rotor iri pakati ichaedza kugadzira. gwara remukati magineti induction line kusvika pazvinobvira.Kutungamira kwekunze kwemagineti mutsara kunopindirana kugadzira pfupi yakavharwa magineti mutsara mutsara, kuitira kuti rotor yemukati itenderere wachi.Kana kutungamira kweiyo rotor magnetic field kunoenderana nekutungamira kwekunze kwemagineti, iyo inotenderera torque ye rotor ndiyo yakakura.Ziva kuti "nguva" inonzi yakakura, kwete "simba".Ichokwadi kuti kana rotor magnetic field iri munzira imwechete neyekunze magnetic field, simba remagineti pa rotor ndiro guru, asi panguva ino rotor iri munzvimbo yakadzika uye simba resimba riri 0, uye re. chokwadi haizotenderere.Kuwedzera, nguva yacho chibereko chesimba uye ruoko rwesimba.Kana chimwe chazvo chiri zero, chigadzirwa chiri zero.Kana iyo rotor ichitendeukira kune yakachinjika chinzvimbo, kunyangwe iyo isingachabatiki neinotenderera torque, icharamba ichitenderera newachi nekuda kwe inertia.Panguva ino, kana hutungamiri huripo hwema solenoids maviri huchishandurwa, sezvinoratidzwa mumufananidzo uri pasi apa, rotor icharamba ichitenderera.tendeuka uchienda mberi,

Munyika 2, hutungamiri huripo hwema solenoids maviri anogara achichinjwa, uye rotor yemukati icharamba ichitenderera.Ichi chiito chekushandura nzira yezvino inonzi commutation.Chinyorwa chepadivi: Nguva yekufamba inongoenderana nechinzvimbo che rotor uye haina hukama zvakananga kune chero humwe huwandu.Chikamu 2: Matatu-chikamu maviri-pole inner rotor mota Kazhinji, matatu-chikamu mahwindi e stator ane nyeredzi yekubatanidza modhi uye delta yekubatanidza modhi, uye "mbiri-mbiri conduction modhi yetatu-phase nyeredzi yekubatanidza" ndiyo inonyanya kuzivikanwa. rinoshandiswa, rinoshandiswa pano.Uyu muenzaniso unoshandiswa pakuongorora nyore.

Mufananidzo uri pamusoro unoratidza kuti stator windings yakabatana sei (rotor haina kuratidzwa seyekufungidzira maviri-pole magineti), uye matatu mhepo yakabatana pamwe chete mu "Y" chimiro kuburikidza nepakati pekubatanidza nzvimbo.Motokari yose inotungamirira kumawaya matatu A, B, C. Pavanenge vapiwa simba maviri maviri, pane 6 kesi, dzinoti AB, AC, BC, BA, CA, CB.Ziva kuti izvi zvakarongeka.

Zvino ini ndinotarisa padanho rekutanga: AB chikamu chinopihwa simba

Kana iyo AB chikamu ichisimbiswa, kutungamira kweiyo magineti mutsara unogadzirwa neA pole coil inoratidzwa nemuseve mutsvuku, uye kutungamira kweiyo magnetic field line inogadzirwa neB pole inoratidzwa nemuseve webhuruu, ipapo kutungamira. yesimba rinoguma rinoratidzwa nemuseve wegirini, zvino Tichifunga kuti kune magineti maviri-pole, iyo N-pole kutungamira ichaenderana negwara rinoratidzwa nemuseve wegirini zvinoenderana ne "rotor iri pakati ichaedza kuchengeta nzira yemitsara yayo yemukati yemagineti inopindirana negwara remitsara yekunze yemagineti”.Kana ari C, haana chekuita naye panguva ino.

Inotevera dhiyagiramu yemamiriro epakati magineti (rotor):Yese process rotor inotenderera 60 madhigirii.

Kutenderera kwakazara kunopedzwa mumatanho matanhatu, ayo matanhatu ekuchinja anoitwa.Chikamu chechitatu: matatu-phase multi- winding multi-pole inner rotor motor Ngatitarisei pane imwe pfungwa yakaoma.Figure (a) ichitatu-chikamu chepfumbamwe-inotenderedza matanhatu-pole (nhatu-chikamu, mapfumbamwe-inopeperetswa, matanhatu-pole) mota.Opposite pole) yemukati rotor mota, iyo inomonereka yekubatanidza inoratidzwa mumufananidzo (b).Zvinogona kuonekwa kubva kuMufananidzo (b) kuti mafungu matatu-matatu akabatanidzwa zvakare pamwe chete panzvimbo yepakati, iyo iriwo nyeredzi yekubatanidza.Kazhinji, nhamba yemhepo inotenderera yemotokari haienderane nehuwandu hwemagineti echigarire (semuenzaniso, 9 windings uye mapango matanhatu anoshandiswa panzvimbo ye6 windings nemapango matanhatu), kuitira kudzivirira mazino e stator uye magineti e rotor kubva pakukwezva uye kubatanidza.

Nheyo yekufamba kwayo ndeyokuti: N danda re rotor uye S danda remhepo ine simba rine maitiro ekugadzirisa, uye S danda re rotor uye N danda remhepo ine simba rine tsika yekuenzanisa.Ndiko kuti, S uye N zvinokwezva mumwe nemumwe.Cherechedza kuti yakasiyana nenzira yekuongorora yapfuura.Zvakanaka, ngatikubatsirei kuiongorora zvakare.Danho rekutanga: AB chikamu chinoiswa magetsi
