Kutaura nezve kumashure emagetsi emagetsi echigarire magineti synchronous mota

1. Kumashure kwe electromotive simba kunogadzirwa sei?

Back electromotive force inonziwo induced electromotive force. Nheyo: conductor inocheka mitsara yemagineti yesimba.

Iyo rotor yekusingaperi magineti synchronous mota igineti yekusingaperi, uye stator yakakuvadzwa nemakoiri. Kana rotor ichitenderera, iyo magineti inogadzirwa negineti yekusingaperi inochekwa nemakoiri ari pa stator, ichigadzira kumashure emagetsi emagetsi pacoil (mune nzira yakatarisana neiyo terminal voltage U).

2. Ukama pakati pemusana electromotive simba uye terminal voltage

3. Chirevo chemuviri chemusana electromotive simba

Kumashure EMF: inogadzira simba rinobatsira uye inopindirana nekupisa kurasikirwa (inoratidza kugona kwekushandura kwechishandiso chemagetsi).

4. Hukuru hwemusana electromotive simba

Pfupiso:

(1) Iyo kumashure EMF yakaenzana neyero yekuchinja kwemagineti flux. Iyo yakakwirira kumhanya, iyo yakakura chiyero chekuchinja uye yakakura kumashure EMF.

(2) Flux pachayo yakaenzana nenhamba yekutendeuka inowedzerwa nekuyerera pachedu. Naizvozvo, iyo yakakwira nhamba yekutendeuka, yakakura iyo flux uye yakakura kumashure EMF.

(3) Nhamba yekutendeuka inoenderana nechirongwa chekutenderera, nyeredzi-delta yekubatanidza, nhamba yekutendeuka pane slot, nhamba yezvikamu, nhamba yemazino, nhamba yematavi akafanana, uye yakazara-pitch kana pfupi-pitch scheme;

(4) Iyo single-turn flux yakaenzana neiyo magnetomotive simba rakakamurwa nemagineti kuramba. Naizvozvo, iyo yakakura iyo magnetomotive simba, idiki iyo magineti kuramba munzira yekuyerera uye yakakura kumashure kwemagetsi emagetsi.

(5) Magnetic kuramba ine hukama nemhepo gap uye pole-slot kurongeka. Iyo yakakura iyo gap yemhepo, iyo yakakura iyo magineti kuramba uye diki kumashure emagetsi emagetsi. Iyo pole-slot coordination yakaoma uye inoda ongororo chaiyo;

(6) Iyo magnetomotive simba ine hukama neasara magineti egineti uye inoshanda nzvimbo yemagineti. Iyo yakakura magineti yakasara, inokwidza kumashure emagetsi emagetsi. Nzvimbo inoshanda ine hukama negwara remagineti, saizi uye kuiswa kwemagineti, izvo zvinoda kuongororwa kwakadzama;

(7) Remanence zvakare inoenderana nekupisa. Iyo yakakwirira tembiricha, iyo idiki kumashure EMF.

Muchidimbu, izvo zvinokanganisa kumashure EMF zvinosanganisira kumhanya kwekutenderera, nhamba yekutendeuka pane slot, nhamba yezvikamu, nhamba yematavi akafanana, yakazara pitch uye pfupi pitch, mota magineti wedunhu, kureba kwemhepo, pole-slot matching, magineti simbi remanence, magineti simbi kuiswa uye saizi, magineti simbi magnetization kutungamira, uye tembiricha.
