Nei zvechigarire magineti mota dzichichengetedza simba?

Mumakore mashoma apfuura, iyo mota indasitiri kana iyo yakakwirira chimiro chechigarire magineti mota, dhigirii remukurumbira rinoratidza maitiro ari kukura. Zvinoenderana nekuongorora, chikonzero nei magineti echigarire angave ane hanya zvakapetwa kaviri, asingaparadzanisiki kubva pakutsigirwa kwakasimba kweiyo nyika marongero kusvika kune yakakwira-inoshanda magineti mota semumiriri wemhando yepamusoro, yepamusoro-yepamusoro-inoshanda zvigadzirwa zvemotokari zvinogona kukurumidza kufarirwa kubatsira kuchengetedza simba uye kuderedza kuburitsa, kuchengetedza makomo akasvibira nemvura yakasvibira. Kuchengetedza magetsi uye kuchengetedzwa kwezvakatipoteredza kunofanira kunge kuri kweramangwana rekusimudzira maitiro, kunyanya muindasitiri yemotokari, magineti echigarire emagetsi ekuchengetedza simba maficha anoratidza mabhenefiti ayo kubva pachiyero chekuchengetedza simba anogona kunge akakwira kupfuura 20%, pasirese isingawanzo magineti emagetsi ekuchengetedza simba anotevera:

Rare pasi pechigarire magineti mota zvitanhatu zvekuchengetedza simba zvakanakira

1, inogara magineti mota pane yakajairwa mota simba rekuchengetedza 5% -30%, chaiyo michina yekushanda mamiriro eakasiyana ekuchengetedza magetsi akasiyana.

2, yekusingaperi magineti synchronous mota kuti iwane mwero wesimba rekuita, kushanda nesimba kweanopfuura 95%; akajairwa matatu-chikamu asynchronous mota ine matatu simba rekuita, simba rekuita rinongosvika 90%.

3, magineti echigarire synchronous mota rotor ine isingawanzo pasi isingaperi magineti simbi, haidi stator kuti ipe induction simba, pane yakajairika mota kurasikirwa idiki;

4, inogara magineti synchronous mota stator lead waya ndeye nyeredzi (Y) yekubatanidza, inogona kuchengetedza simba risingachinjiki ikozvino idiki; mota dzakajairwa kazhinji △ kubatana;

5, inogara magineti synchronous mota mukuita basa, kana mutoro uchichinja kana kukosha kwesimba kuchigona kuramba kusachinjika, yakajairwa asynchronous mota kana mutoro uchichinja kana kukosha kwesimba kuchichinja, yakajairwa asynchronous mota mumutoro unosvika pamatatu ehukoshi hwekusimba kwesimba haina kuchinjika, kana mutoro usiri pasi pe70% yekukosha kwesimba rayo.

6, magineti echigarire synchronous mota hapana-mutoro wazvino idiki, chikamu chimwe chete mugumi cheyakayerwa ikozvino, nepo yakajairwa asynchronous mota mune isina-mutoro wazvino kusvika pachikamu chimwe chete muzvitatu.

Rare pasi pechigarire magineti mota zvikamu zvitatu zvikuru

1, Rare pasi pechigarire magineti mota inotora yakakwirira-inoshanda magineti isingaperi, iyo inobvisa iko zvino kunakidzwa kweiyo stator kana rotor chikamu chemota, saka inobvisa kurasikirwa kwemhangura kwechikamu ichi (kupeta kupisa kurasikirwa);

2, kushandiswa kwebrushless chimiro, hapana kabhoni brashi chimiro chekurasikirwa kwemechani, asi brushless mota iri kuburikidza nemagetsi commutation chimiro kuona kutenderera, pano pane chikamu chemagetsi zvikamu zvekurasikirwa, uye chengetedza kurasikirwa kwemakanika kana kuenzaniswa nekurasikirwa kukosha idiki, saka chikamu chekuchinja chekurasikirwa pane kurasikirwa kwebhurashi mota kurasikirwa idiki;

3, kushandiswa kweakakwirira-isingawanzo epasi magineti asingagumi, mune imwechete yakayerwa simba uye yakayerwa kumhanya, iyo mota vhoriyamu inogona kuitwa idiki, kuchengetedza mota silicon simbi pepa, kuderedza chikamu chekurasika kwesimbi. Madiki emagetsi mota anoshandisa isingawanzo pasi isingaperi magineti mota inogona kusvika pedyo ne90% kunyatsoshanda, iyo general mota ingangoita 75%.

Iko kushandiswa kwePMSM kwave kuita kuti mabhizinesi achengetedze simba, kuderedza kuburitswa, uye kuwana kukunda-kuhwina girinhi budiriro.
