Sei mota dzema frequency akasiyana-siyana dziine ma cage rotor structures?

Rotor yerondamotaine resistor yakabatana nerotor, zvekuti mota ine torque yakakura zvakakwana yekutanga uye current diki kwazvo yekutanga (multiple ye starting current inenge yakaenzana ne multiple ye starting torque), uye inogonawo kuita basa rekudzora kumhanya kwenzvimbo diki.

Mota dzemafrequency akasiyana-siyana dzinogona kuita mabasa ekudzora kumhanya nekumhanya zvakapfava nekuchinja mafrequency. Mupfungwa, kumhanya kubva pa0 kusvika kuinfinity kunogona kugadziriswa zvakanaka, asi kutaura zvazviri, kumhanya kwakaderera kwakabatana nehunhu hwemafrequency akaderera emota, uye kumhanya kwakanyanya kunogumira nekumhanya kwemuganho wekubata; Nzvimbo yakachengeteka yekushanda inobva pa0 kusvika pakumhanya kwakarongwa, iyo inogona kushanda pasi kana kuenzana netorque yakarongwa, uye kubva pakumhanya kwakarongwa kusvika pakumhanya kukuru, iyo inogona kushanda pasi kana kuenzana nesimba rakarongwa. Naizvozvo, mota yefrequency inoshanduka ine torque inogara iripo kubva pa0 kusvika pakumhanya kwakarongwa uye yakakwira kupfuura kumhanya kwakarongwa. Hunhu hwekutonga kumhanya kwesimba nguva dzose.

Kubva pakuongorora chimiro chemota, mota yekeji ine chimiro chakareruka, haina kuoma kugadzira, uye yakasimba zvikuru maererano nesimba remuchina. Inoita mabasa ekudzora kudzika nekumhanya kuburikidza ne frequency converter, uye kumhanya kwayo kwakanyanya kupfuura kwe three-phase asynchronous winding rotor. Chimiro chemota ne commutator mota yeDC imota inotyaira nekukurumidza uye inodhura zvishoma uye yakavimbika.

Panyaya yedzidziso, mota ye rotor ye wound inogona kumhanya pa frequency inochinja-chinja, asi rotor ye wound inorasikirwa nehunhu hwakanaka hwekutanga ne resistance yekunze uye speed regulation. Kushanda kwe soft start kwe variable frequency method kwakaderera zvikuru pane kwe squirrel cage motor (resistance ye wound rotor idiki, uye starting torque idiki), uye rotor winds. Kune njodzi dzakavanda dzemagetsi dzakadai se turn-to-ground uye phase-to-phase short circuits uye high-speed shedding. Dambudziko rekuvimbika rakaderera zvikuru pane re solid squirrel cage rotor. Nokudaro, kuwedzera kune doubly-fed speed-regulated asynchronous generators kana internally-fed speed-regulated asynchronous motors, winding Line rotor motors hadzishandise variable frequency power supply.
