Lebelo le Phahameng la AC Motor
Enjene ea ACke sesebediswa se fetolang matla a motlakase a matla a feto-fetohang ho ba matla a motjhini.Enjene ea AC e na haholo-holo le matsoelintsoeke a makenete ea elektronike kapa matsoelintsoeke a stator a phatlalalitsoeng a sebelisetsoang ho hlahisa matla a khoheli le letsoho le potolohang kapa rotor.Enjene e entsoe ka ho sebelisa ts'ebetso ea ho potoloha khoele e matlafalitsoeng ka matla a khoheli.Ho na le mefuta e 'meli ea li-motor tsa AC: li-motor tsa synchronous AC le li-motors tsa induction.
The stator winding ea mekhahlelo e meraro ea AC motor ha e le hantle ke li-coil tse tharo tse arohaneng ka likhato tse 120 ho tloha ho tse ling, tse hokahaneng ka sebopeho sa kgutlotharo kapa sa linaleli.Ha motlakase oa mekhahlelo e meraro o sebelisoa, matla a khoheli a hlahisoa ho coil ka 'ngoe,' me matla a mararo a khoheli a kopantsoe ho fumana matla a khoheli a potolohang.
Enjene ea ACe na le stator le rotor, 'me ho na le mefuta e' meli ea li-motor tsa AC: enjene ea AC ea synchronous le motor induction.Mefuta ena ka bobeli ea li-motor e hlahisa matla a khoheli a potolohang ka ho fetisa AC hona joale sebakeng sa stator winding, empa moea oa rotor oa synchronous AC motor hangata o hloka ho fanoa ka DC ea hajoale (excitation current) ke exciter, ha moea oa rotor oa induction motor o sa etse joalo. hloka ho feptjoa ka metsi.
The stator winding ea mekhahlelo e meraro ea AC motor ha e le hantle ke li-coil tse tharo tse arohaneng ka likhato tse 120 ho tloha ho tse ling 'me li hokahane ka kgutlotharo kapa sebopeho sa naleli.Ha motlakase oa mekhahlelo e meraro o sebelisoa, matla a khoheli a hlahisoa ka har'a coil ka 'ngoe,' me masimo a mararo a kopantsoe ho fumana tšimo e potolohang.Ha motlakase o qeta ho thothomela ka botlalo, matla a khoheli a potolohang a potoloha hantle beke e le 'ngoe, ka hona, liphetoho ka motsotso oa matla a khoheli a potolohang N=60f.Equation f ke maqhubu a phepelo ea motlakase.
Li-motor tsa AC li ka aroloa ka li-motor tse lumellanang le li-asynchronous motors (kapa li-motor tse seng tsa synchronous) ho latela sekhahla sa ho potoloha ha rotor.Lebelo la rotor la motor synchronous le lula le lekana le lebelo la matla a khoheli a potolohang ho sa tsotelehe mojaro, ka hona lebelo lena le bitsoa lebelo la synchronous, mme joalo ka ha ho boletsoe ka holimo, le khethoa feela ka makhetlo a phepelo ea matla.Lebelo la motlakase oa asynchronous ha le fetohe, empa le itšetlehile ka boholo ba mojaro le matla a motlakase.Har'a li-motor tse tharo tsa asynchronous motors, ho na le li-motor tse sa lokiseng le li-motor tse nchafatsang.Boholo ba li-motor tsa asynchronous tse sebetsang ke li-induction motors ntle le rectifier (empa parallel le letoto la likarolo tse tharo tsa asynchronous rectifier motors li na le melemo ea lebelo le feto-fetohang maemong a mangata le matla a phahameng), 'me lebelo la eona le lula le le tlase ho feta lebelo la synchronous. .
Lisebelisoa tse ka sehloohong
Enjene ea ACe na le katleho e phahameng ea ho sebetsa, 'me ha e na mosi, lerōle le monko, ha e na tšilafalo ea tikoloho, le lerata le fokolang.Ka lebaka la letoto la melemo ea eona, e sebelisoa haholo likarolong tse fapaneng tse kang tlhahiso ea indasteri le ea temo, lipalangoang, tšireletso ea naha, lisebelisoa tsa khoebo le tsa malapa, lisebelisoa tsa motlakase tsa bongaka, joalo-joalo.
