Ndedzipi nzira dzekuderedza simba rekutanga kwemota?

1. Kutanga zvakananga

Kutanga zvakananga inzira yekubatanidza zvakanangastatorkutenderedzwa kwemota yemagetsikumagetsi uye kutanga pamagetsi akarongwa. Ine hunhu hwe starting torque yakakwira uye nguva pfupi yekutanga, uye ndiyo nzira iri nyore yekutanga, isingadhuri zvakanyanya, uye yakavimbika. Kana uchitanga pamagetsi akazara, magetsi anowedzera uye starting torque haina kukura, zvichiita kuti zvive nyore kushanda uye nekukurumidza kutanga. Zvisinei, nzira iyi yekutanga ine zvinodiwa zvakanyanya zve grid capacity uye mutoro, uye inonyanya kukodzera ma starting motors ari pasi pe 1W.

2.Kudzivirira kwemotokari kutanga

Kutanga kwekudzivirira mota series inzira yekuderedza kutanga kwevoltage. Munguva yekutanga, resistor yakabatana mu series mu stator winding circuit. Kana startup current ichipfuura, voltage drop inogadzirwa pa resistor, zvichideredza voltage inoshandiswa pastatorIzvi zvinogona kuzadzisa chinangwa chekuderedza simba rekutanga.

3. Kutanga kwe transformer yekubatanidza yega

Kushandisa multi tap voltage reduction ye autotransformer hakungogumiri pazvinodiwa zvekutanga mutoro wakasiyana, asiwo kuwana starting torque yakakura. Iyi inzira inowanzo shandiswa yekudzikisa voltage yekutanga mota dzine simba rakakura. Chinhu chikuru chakanakira ndechekuti starting torque yakakura. Kana winding tap iri pa80%, starting torque inogona kusvika 64% ye direct starting torque, uye starting torque inogona kugadziriswa kuburikidza ne tap.

4. Kutanga kweDecompression yeNyeredzi Delta

Yekeji yesquirrel isina mota inoshanda zvakajairikastatorKutenderedza kwakabatana nenzira yetriangle, kana kutenderedza stator kwakabatana muchimiro chenyeredzi panguva yekutanga uye kwozobatanidzwa muchimiro chetriangle mushure mekutanga, kunogona kuderedza simba rekutanga uye kuderedza kukanganisa kwayo pagrid yemagetsi. Nzira iyi yekutanga inonzi star delta decompression kutanga, kana kungoti star delta kutanga (y&starting).

Pakushandisa nzira yekutanga ye star delta, simba rekutanga rinongori chikamu chimwe muzvitatu chenzira yekutanga yekutanga uchishandisa nzira yekubatanidza katatu. Pakutanga kwe star delta, simba rekutanga rinongori ka2-2.3 chete. Izvi zvinoreva kuti kana uchishandisa nzira yekutanga ye star delta, simba rekutanga rinodzikiswawo kusvika pachikamu chimwe muzvitatu chezvaraive pakutanga uchishandisa nzira yekubatanidza katatu.

Yakakodzera mamiriro ezvinhu apo pasina mutoro kana mutoro wakareruka unotanga. Uye kana tichienzanisa nedzimwe nzira dzekutanga vacuum, chimiro chayo ndicho chiri nyore uye mutengo wacho ndiwo wakachipawo.

Pamusoro pezvo, nzira yekutanga ye star delta ine mukanawo, ndeyekuti kana mutoro wakareruka, inogona kubvumira mota kushanda pasi penzira yekubatanidza nyeredzi. Panguva ino, torque yakayerwa nemutoro zvinogona kuenzaniswa, izvo zvinogona kuvandudza kushanda kwemota uye kuchengetedza kushandiswa kwemagetsi.

5. Kutanga kwechishanduri cheFrequency (kutanga kwakapfava)

 Chinoshandura ma frequency ndicho chishandiso chekutonga mota chakanyanya kufambira mberi, chinoshanda zvizere, uye chinoshanda zvakanaka mumunda wekutonga mota dzemazuva ano. Chinogadzirisa kumhanya uye torque yemota nekuchinja frequency yegrid yemagetsi. Nekuda kwekubatanidzwa kwetekinoroji yemagetsi emagetsi uye tekinoroji yema microcomputer, mutengo wacho wakakwira uye zvinodiwa nevanyanzvi vekugadzirisa zvakakwirirawo. Saka, inonyanya kushandiswa munzvimbo dzinoda kudzorwa kwekumhanya uye zvinodiwa zvekudzora kumhanya kwakanyanya.
