1. Yenziwa njani amandla e-electromotive angasemva?
Amandla e-electromotive angasemva abizwa ngokuba yi-electromotive force. Umgaqo: umqhubi we-conductor usika imigca yemagnethi yamandla.
I-rotor yemagnethi esisigxina ye-synchronous motor yimagnethi esisigxina, kwaye i-stator inxeba ngeekhoyili. Xa i-rotor ijikeleza, intsimi yamagnetic eveliswa yimagnethi esisigxina inqunywe yi-coil kwi-stator, ivelisa amandla ombane ongemva kwi-coil (kwicala elichasene ne-terminal voltage U).
2. Ubudlelwane phakathi kwamandla e-electromotive angasemva kunye ne-terminal voltage
3. Intsingiselo yomzimba yamandla e-electromotive angasemva
I-EMF yangasemva: ivelisa amandla aluncedo kwaye ihambelana ngokungafaniyo nokulahleka kobushushu (ibonisa amandla okuguqula isixhobo sombane).
4. Ubungakanani be-electromotive force yangasemva
Shwankathela:
(1) I-EMF yangasemva ilingana nezinga lokutshintsha kwe-magnetic flux. Isantya esiphezulu, isantya esikhulu sokutshintsha kunye ne-EMF enkulu ngasemva.
(2) I-flux ngokwayo ilingana nenani lokujika liphindaphindwe ngokuguquguquka ngokujika. Ngoko ke, inani eliphezulu lokujika, i-flux enkulu kunye ne-EMF enkulu yangasemva.
(3) Inani lokujika linxulumene neskimu sokujija, uqhagamshelo lwenkanyezi-delta, inani lokujikela kwindawo nganye, inani lezigaba, inani lamazinyo, inani lamasebe ahambelanayo, kunye neskimu esipheleleyo okanye i-short-pitch scheme;
4 Ke ngoko, ubukhulu be-magnetomotive force, buncinci ukuchasana kwamagnetic kwicala le-flux kunye nobukhulu be-electromotive force yangasemva.
(5) Ukumelana nemagnethi kunxulumene nomsantsa womoya kunye nolungelelwaniso lwe-pole-slot. Okukhona umkhulu umsantsa womoya, kokukhona uxhathiso lwemagnethi kwaye umncinci umva wamandla e-electromotive. Ulungelelwaniso lwe-pole-slot lunzima kwaye lufuna uhlalutyo oluthile;
(6) Amandla emagnetomotive anxulumene nentsalela umazibuthe kunye nendawo esebenzayo umazibuthe. Ubukhulu bemagnethi eyintsalela, kokukhona iphezulu amandla e-electromotive angasemva. Indawo esebenzayo inxulumene nolwalathiso lwemagneti, ubungakanani kunye nokubekwa kwemagnethi, efuna uhlalutyo oluthile;
(7) Ukuhlala kwakhona kunxulumene nobushushu. Ukuphakama kweqondo lokushisa, i-EMF encinci yangasemva.
Isishwankathelo, izinto ezichaphazela i-EMF ngasemva ziquka isantya sokujikeleza, inani lokujika kwi-slot nganye, inani lezigaba, inani lamasebe ahambelanayo, i-pitch epheleleyo kunye ne-pitch emfutshane, i-motor magnetic circuit, ubude be-gap yomoya, i-pole-slot match, i-magnetic steel remanence, ukubekwa kwentsimbi yemagnethi kunye nobungakanani, ulwalathiso lwemagnethi yentsimbi, kunye nobushushu.
