Ukukhuluma ngamandla angemuva e-electromotive of unomphela uzibuthe motor synchronous

1. Amandla angemuva e-electromotive akhiqizwa kanjani?

I-back electromotive force ibizwa nangokuthi i-electromotive force eyenziwe. Isimiso: umqhubi usika imigqa yamandla kazibuthe.

I-rotor ye-magnetic synchronous motor unomphela iyizibuthe unomphela, futhi i-stator ilinyazwe ngamakhoyili. Lapho i-rotor ijikeleza, inkambu kazibuthe ekhiqizwa uzibuthe unomphela isikwa amakhoyili ku-stator, ikhiqize amandla e-electromotive angemuva kukhoyili (ngaphesheya kwe-terminal voltage U).

2. Ubudlelwano phakathi kwamandla e-electromotive angemuva kanye ne-terminal voltage

3. Incazelo ebonakalayo yamandla e-electromotive angemuva

I-EMF Emuva: ikhiqiza amandla awusizo futhi ihlotshaniswa ngokuphambene nokulahlekelwa ukushisa (ibonisa ikhono lokuguqula into esebenza ngogesi).

4. Ubukhulu bamandla e-electromotive angemuva

Fingqa:

(1) I-EMF yangemuva ilingana nezinga lokushintsha kwe-flux kazibuthe. Lapho ijubane liphakeme, izinga loshintsho likhulu futhi i-EMF yangemuva inkulu.

(2) I-flux ngokwayo ilingana nenani lokujika eliphindwe ngokushintshashintsha ngokujika ngakunye. Ngakho-ke, lapho inani lokujika liphakeme, i-flux inkulu futhi i-EMF yangemuva inkulu.

(3) Inani lokujika lihlobene nohlelo lokujikajika, ukuxhunywa kwenkanyezi ne-delta, inani lamajika endaweni ngayinye, inani lezigaba, inani lamazinyo, inani lamagatsha ahambisanayo, nohlelo lwephimbo eligcwele noma le-short-pitch;

(4) I-single-turn flux ilingana namandla kazibuthe ahlukaniswe amandla kazibuthe. Ngakho-ke, amandla amakhulu e-magnetomotive, amancane amandla kazibuthe ekuqondeni kwe-flux kanye namandla angemuva e-electromotive.

(5) Ukumelana namagnetic kuhlobene negebe lomoya kanye nokuxhumana kwesigxobo sesigxobo. Uma sikhulu igebe lomoya, amandla amakhulu kazibuthe kanye namandla e-electromotive angemuva. Ukuxhumanisa i-pole-slot kuyinkimbinkimbi futhi kudinga ukuhlaziywa okuqondile;

(6) Amandla kazibuthe ahlobene nozibuthe osalayo kanye nendawo esebenzayo kazibuthe. Uma uzibuthe osele umkhulu, amandla e-electromotive angemuva aphezulu. Indawo ephumelelayo ihlobene nesiqondiso samagnetization, ubukhulu kanye nokubekwa kwamagnet, okudinga ukuhlaziywa okuqondile;

(7) I-Remanence nayo ihlobene nezinga lokushisa. Uma izinga lokushisa liphakeme, i-EMF yangemuva incane.

Kafushane, izici ezithinta i-EMF emuva zifaka isivinini sokujikeleza, inani lokujika kwendawo ngayinye, inani lezigaba, inani lamagatsha ahambisanayo, iphimbo eligcwele kanye nephimbo elifushane, isekethe kazibuthe yemoto, ubude begebe lomoya, ukufanisa i-pole-slot, i-magnetic steel remanence, ukubekwa kwensimbi kazibuthe nosayizi, isiqondiso sikazibuthe ensimbi, kanye nezinga lokushisa.
