Umthetho wesandla sasekhohlo, umthetho wesandla sasekunene, umthetho wesandla sasekunene sesijifu.Umthetho wesandla sasekhohlo, oku kusisiseko sohlalutyo lwamandla okujikeleza kwemoto.Ukubeka nje, ngumqhubi ophetheyo ngoku kwintsimi yamagnetic, eya kuchaphazeleka ngamandla.

Vumela umgca wemagnethi udlule phambi kwesundu, isalathiso seminwe sisalathiso sangoku, kwaye isalathiso sesithupha sisalathiso samandla kazibuthe.Ukutsalwa kwamandla kusika imigca yomhlaba wemagnethi ukuvelisa amandla e-electromotive.

Vumela umgca wemagnethi udlule entendeni, isalathiso sobhontsi sisikhokelo sokunyakaza, kwaye isalathiso somnwe sisalathiso samandla ombane avelisiweyo.Kutheni uthetha malunga ne-electromotive force eyenziwe?Andazi ukuba unawo nawaphi na amava afanayo.Xa udibanisa iingcingo ezithathu zemoto kwaye ujike i-motor ngesandla, uya kufumanisa ukuba ukuchasana kukhulu kakhulu.Oku kungenxa yokuba ukuqaliswa kwenzeka ngexesha lokujikeleza kwemoto.I-electromotive force ivelisa i-current, kwaye i-current flowing through conductor in the magnetic field iya kuvelisa amandla achasene nolwalathiso lokujikeleza, kwaye wonke umntu uya kuziva ukuba kukho ukuchasana okukhulu ukujikeleza.

Iingcingo zamanqanaba amathathu ziyahlukana kwaye i-motor inokujika ngokulula

Imigca yesigaba sesithathu idibaniswe, kwaye ukuchasana kwemoto kukhulu kakhulu.Ngokomthetho we-screw wesandla sasekunene, bamba i-solenoid ene-energized ngesandla sokunene, ukuze iminwe emine igobe kwicala elifanayo njengangoku, emva koko isiphelo esikhonjwe ngubhontsi yiN pole ye-solenoid energized.

Lo mgaqo usisiseko sokugweba i-polarity yekhoyili esebenzayo, kwaye isalathiso sotolo olubomvu lukhokelo lwangoku.Emva kokufunda imigaqo emithathu, makhe sijonge imigaqo esisiseko yokujikeleza kweemoto.Inxalenye yokuqala: Imodeli yeemoto ze-DC Sifumana imodeli yemoto ye-DC eye yafundwa kwi-physics yesikolo samabanga aphakamileyo, kwaye yenza uhlalutyo olulula ngokusebenzisa indlela yohlalutyo lwesekethe yemagnethi.

Isimo 1 Xa i-current isetyenziswe kwiikhoyili kuzo zombini iziphelo, ngokomthetho we-screw wesandla sasekunene, i-induction intensity esetyenzisiweyo ye-B (njengoko kubonisiwe lutolo olungqindilili) iya kuveliswa, kwaye i-rotor embindini iya kuzama ukwenza. isalathiso somgca wayo wangaphakathi wokungenisa imagnethi kangangoko kunokwenzeka.Isalathiso somgca wemagnethi yangaphandle iyahambelana ukwenza i-loop yomgca wemagnethi evaliweyo, ukwenzela ukuba i-rotor yangaphakathi ijikeleze ngewotshi.Xa i-rotor magnetic field i-perpendicular ukuya kwicala le-magnetic field yangaphandle, i-torque ejikelezayo ye-rotor inkulu.Qaphela ukuba "umzuzu" kuthiwa ngowona mkhulu, kungekhona "umandla".Kuyinyani ukuba xa i-rotor magnetic field ikwicala elifanayo kunye ne-magnetic field yangaphandle, amandla amagnetic kwi-rotor ngowona mkhulu, kodwa ngeli xesha i-rotor ikwimeko ethe tye kwaye ingalo yamandla ngu-0, kwaye ngokuqinisekileyo ayiyi kujikeleza.Ukongeza, umzuzu uyimveliso yamandla kunye nengalo yomkhosi.Ukuba enye yazo ingu-zero, imveliso ingu-zero.Xa i-rotor ijika kwindawo ethe tye, nangona ingasachatshazelwa yi-torque ejikelezayo, iya kuqhubeka ijikeleza nge-clockwise ngenxa ye-inertia.Ngeli xesha, ukuba ulwalathiso lwangoku lwee-solenoids ezimbini lutshintshile, njengoko kuboniswe kumzobo ongezantsi, i-rotor iya kuqhubeka ijikeleza.jikela phambili ngasekunene,

Kwimeko ye-2, ulwalathiso lwangoku lwee-solenoids ezimbini luhlala lutshintshwa, kwaye i-rotor yangaphakathi iya kuqhubeka ijikeleza.Esi senzo sokutshintsha indlela yangoku sibizwa ngokuba kukuhamba.Inqaku elisecaleni: Ixesha lokuhamba lihambelana kuphela nendawo ye-rotor kwaye ayihambelani ngokuthe ngqo naluphi na ubuninzi.Isigaba 2: Isigaba sesithathu semotor yerotor yangaphakathi enepoleni ezimbini Ngokuqhelekileyo, izigaba ezithathu zokujija zestator zinemowudi yoqhagamshelo lwenkwenkwezi kunye nemowudi yoqhagamshelo lwedelta, kwaye "imowudi yokuqhuba ezimbini-ezimbini zoqhagamshelo lweenkwenkwezi ezithathu" yeyona ixhaphakileyo. esetyenzisiweyo, esetyenziswa apha.Lo mzekelo usetyenziselwa uhlalutyo olulula.

Umfanekiso ongasentla ubonisa indlela i-stator windings edibeneyo ngayo (i-rotor ayiboniswa njenge-hypothetical-pole-pole magnet), kwaye i-windings emithathu idibaniswe kunye kwi-"Y" imilo ngendawo yokudibanisa ephakathi.Imoto yonke ikhokelela kwiingcingo ezintathu A, B, C. Xa zinikwe amandla ngambini ngambini, kukho iimeko ezi-6, ezizezi: AB, AC, BC, BA, CA, CB.Qaphela ukuba oku kulungile.

Ngoku ndijonge inqanaba lokuqala: Inqanaba le-AB linamandla

Xa isigaba se-AB senziwe amandla, isalathiso somgca wemagnethi oveliswa yi-A pole coil iboniswa lutolo olubomvu, kwaye isalathiso somgca wemagnethi oveliswe sisibonda esingu-B siboniswa lutolo oluluhlaza, emva koko isalathiso somgca wemagnethi esiveliswe sisibonda esingu-B siboniswa lutolo oluluhlaza. Isiphumo samandla esiphumo siboniswa lutolo oluluhlaza, ngoko Ukucinga ukuba kukho imagnethi enepoleni ezimbini, ulwalathiso lwe-N-pole luya kuhambelana nolwalathiso oluboniswa lutolo oluluhlaza ngokwe “rotor embindini uya kuzama ukugcina intsingiselo yemigca yayo yangaphakathi yemagnethi ehambelana nelathiso yemigca yemagnethi yangaphandle”.UC yena akananto yakwenza naye okwangoku.

Inqanaba lesi-2: Inqanaba le-AC elinikwe amandla

Inqanaba lesithathu: BC isigaba sokufakelwa kombane

Inqanaba lesithathu: Inqanaba le-BA linikwe amandla

Oku kulandelayo ngumzobo wemeko yemagnethi ephakathi (irotha):Irotha yenkqubo nganye ijikeleza idigri ezingama-60.

Ujikelezo olupheleleyo luqukunjelwa kwiinkqubo ezintandathu, apho kwenziwa uhlengahlengiso ezintandathu.Inxalenye yesithathu: inqanaba lesithathu i-multi-winding multi-pole yangaphakathi ye-rotor motor Makhe sijonge inqaku elinzima ngakumbi.Umzobo (a) yinqanaba lesithoba elijikela kwipali ezintandathu (inqanaba lesithathu, elithoba-ukujikajika, elineepali ezintandathu).Ipali echaseneyo) i-rotor motor yangaphakathi, uxhulumaniso lwayo olujikelezayo luboniswa kumfanekiso (b).Ingabonwa ukusuka kuMzobo (b) ukuba i-winding phases ezintathu nayo idibaniswe kunye kwindawo ephakathi, ekwalunxibelelwano lweenkwenkwezi.Ngokuqhelekileyo, inani le-winding ye-motor alihambelani nenani leepali zemagnethi ezisisigxina (umzekelo, i-9 windings kunye neepali ezi-6 zisetyenziswa endaweni ye-6 windings kunye neepali ezi-6), ukukhusela amazinyo e-stator kunye ne-stator. iimagnethi zerotor ukusuka ekutsaleni nasekulungelelaniseni.

Umgaqo wokuhamba kwayo ngulo: I-N pole ye-rotor kunye ne-S pole ye-energized winding inomkhuba wokulungelelanisa, kunye ne-S pole ye-rotor kunye ne-N pole ye-energized winding inomkhuba wokulungelelanisa.Oko kukuthi, u-S no-N batsalelana.Qaphela ukuba ihluke kwindlela yokuhlalutya yangaphambili.Kulungile, masikuncede uyihlalutye kwakhona.Inqanaba lokuqala: Inqanaba le-AB lifakelwa umbane

Inqanaba lesi-2: Inqanaba le-AC elinikwe amandla

Inqanaba lesithathu: BC isigaba sokufakelwa kombane
