1, AC motor asynchronous

I-AC i-asynchronous motor yimoto yombane ehamba phambili ye-AC, esetyenziswa kakhulu kwiifeni zombane, iifriji, oomatshini bokuhlamba, i-air conditioner, izomisi zeenwele, izicoci zokucoca, iihoods zoluhlu, oomatshini bokuhlamba izitya, oomatshini bokuthunga bombane, oomatshini bokulungisa ukutya kunye nezinye izixhobo zasekhaya, njengoko kunye nezixhobo zombane ezahlukeneyo kunye nezixhobo zombane ezincinci.

I-AC ye-asynchronous motor yahlulwe kwi-induction motor kunye ne-AC commutator motor.I-motor induction yahlulwe yangakwinqanaba elinye le-asynchronous motor, i-AC / DC motor kunye ne-repulsion motor.

Isantya se-motor (isantya se-rotor) singaphantsi kwesantya se-magnetic field ejikelezayo, ngoko kuthiwa yi-asynchronous motor.Ngokusisiseko iyafana nemoto yokungenisa.S = (ns-n) / NS.S lizinga lokutyibilika,

I-NS yisantya semagnethi kwaye i-N isantya serotor.

Umgaqo osisiseko:

1. Xa inqanaba lesithathu lenqanaba le-asynchronous motor liqhagamshelwe kwisigaba sesithathu sombane we-AC, inqanaba lesithathu le-stator elijikelezayo liqukuqela ngamandla amanqanaba amathathu emagnetomotive (i-stator ejikelezayo ye-magnetomotive force) eyenziwe yi-symmetrical current yesigaba sesithathu kwaye ivelisa. indawo yemagnethi ejikelezayo.

2. Intsimi yamagnetic ejikelezayo inentshukumo yokusika isalamane kunye ne-rotor conductor.Ngokomgaqo wokungeniswa kwe-electromagnetic induction, i-rotor conductor ivelisa amandla e-electromotive kunye ne-induced yangoku.

3. Ngokomthetho wamandla ombane we-electromagnetic force, i-rotor conductor yangoku ichaphazeleka ngamandla e-electromagnetic kwintsimi yamagnetic ukwenza i-torque ye-electromagnetic kwaye iqhube i-rotor ukuba ijikeleze.Xa kukho umthwalo womatshini kwi-motor shaft, iya kukhupha amandla oomatshini ngaphandle.

I-Asynchronous motor luhlobo lwe-AC motor, kwaye umlinganiselo wesantya phantsi komthwalo ukuya rhoqo kwigridi yamandla edibeneyo ayitshintshi.Ikwatshintsha kunye nobukhulu bomthwalo.Inkulu i-torque yomthwalo, isantya esisezantsi se-rotor.I-Asynchronous motor ibandakanya i-induction motor, i-motor induction induction ephindwe kabini kunye ne-AC commutator motor.Injini yokungenisa yeyona isetyenziswa kakhulu.Ngokuqhelekileyo inokubizwa ngokuba yi-asynchronous motor ngaphandle kokubangela ukungaqondi okanye ukudideka.

I-stator winding ye-motor ye-asynchronous eqhelekileyo ixhunyiwe kwigridi yamandla e-AC, kwaye i-rotor winding ayifuni ukudibaniswa neminye imithombo yamandla.Ngoko ke, ineenzuzo zesakhiwo esilula, ukuveliswa okulula, ukusetyenziswa kunye nokugcinwa, ukusebenza okuthembekileyo, umgangatho ophantsi kunye neendleko eziphantsi.I-Asynchronous motor inokusebenza okuphezulu kunye neempawu ezilungileyo zokusebenza.Ibaleka ngesantya esingaguqukiyo ukusuka ekungangeni mthwalo ukuya kumthwalo opheleleyo, onokuhlangabezana neemfuno zothumelo lwemveliso emininzi yoomatshini bemveliso yezolimo.Iinjini zeAsynchronous zikwalula ukuvelisa iintlobo ezahlukeneyo zokhuseleko ukuhlangabezana neemfuno zeemeko ezahlukeneyo zokusingqongileyo.Xa i-asynchronous motor isebenza, amandla okuvuselela asebenzayo kufuneka afunwe kwigridi yamandla ukuze wonakalise amandla ombane wegridi yamandla.Ke ngoko, iimotor ezilungelelanisiweyo zihlala zisetyenziselwa ukuqhuba izixhobo zombane eziphezulu kunye nesantya esisezantsi esinje ngeebhola zebhola kunye neecompressors.Ngenxa yokuba isantya semoto ye-asynchronous inobudlelwane obuthile bokutyibilika kunye nesantya semagnethi esijikelezayo, ukusebenza kwayo kokulawulwa kwesantya kubi (ngaphandle kwemoto yokuhambisa i-AC).Imoto ye-DC inoqoqosho ngakumbi kwaye ilungele oomatshini bothutho, ilitye lokusila, isixhobo esikhulu somatshini, ukuprinta kunye nokudaya kunye noomatshini bokwenza amaphepha abafuna uluhlu olubanzi nolugudileyo lolawulo lwesantya.Nangona kunjalo, ngophuhliso lwezixhobo zombane ezinamandla aphezulu kunye nenkqubo yokulawula isantya se-AC, ukusebenza kolawulo lwesantya kunye noqoqosho lwemoto ehambelana neasynchronous efanelekileyo kulawulo lwesantya esibanzi xa ithelekiswa nemoto yeDC.
