Asynchronous ib leeg-theem lub cev muaj zog tsev thiab nws cov kev twb kev txuas

Tib theem asynchronous lub cev muaj zog yog ib lub tshuab uas converts hluav taws xob lub zog mus rau hauv cov neeg kho tshuab zog, nyob rau hauv daim ntawv ntawm ib tug tso tawm torque nyob rau hauv nws ncej. Nws tau txais nws lub npe vim hais tias los ntawm kev ua tus ncej ceev txo nws load, qab lub rotating teb zaus. Qhov txawv ntawm cov speeds yog hu ua ris hauv qab.

Nws muaj asynchronous ib leeg-theem lub cev muaj zog, raws li zoo raws li tag nrho cov hluav taws xob lub tsheb, ntawm ob lub ntsiab qhov chaw - lub stator thiab rotor. Hauv lub davhlau ya nyob twg box, tsau mus rau lub cev, cov lus xaus, qhia nyob rau hauv ntau txoj kev. Plaub ntawm lawv, thiab mus cuag lawv kom raug, koj yuav tsum to taub lub ntsiab ntawm txhua tus ntawm ob tug officers ntawm nyob ntawm tej.

Los ntawm cov ib txwm peb-theem asynchronous electric tsav tib theem lub cev muaj zog sib txawv tus naj npawb ntawm coils thiab lawv configuration. Ob tug ntawm lawv, thiab lawv yuav tsis tib yam. Lub hom Winding tsim los ua ib tug yam magnetic teb elliptical zoo.

Thaum ib txoj cai lub nrog hwm thereto yog ib tug ntxiv los yog koom haum pab kauj, generating torque, tsim nyog mus impart ib tug thawj zaug kev sib hloov ntawm lub rotor. Qhov yuav tsum tau rau no caij vim rau qhov tseeb hais tias ib tug hluav taws xob winding excites lub magnetic teb symmetry axis uas tseem taag, thiab yog li ntawd, kom tshem tau cov rotor los ntawm qhov chaw yuav tsum tau ntxiv dag zog. Nws elliptical daim ntawv no, thiab nws yuav tuaj raws li lub sum ntawm ob ncig teb nrog opposite qhia, yog ib tus uas muaj txhawb rau txoj kev sib hloov, thiab lwm yam ua rau nws. Cov yam ntxwv ntawm xws li ib tug tshuab rau qhov no yog vim li cas, heev npaum li cas tshaj peb theem, tab sis mus rau muab tso rau mus nrog no tsis muaj peev xwm nyob rau hauv ib tug ca los yog lub tsev.

Raws li txoj cai, ib leeg-theem asynchronous tsav - lub tsheb uas tsis muaj hwj chim uas koj siv ntau rau hluav taws xob khoom vaj khoom tsev. Piv txwv yog cov plaub hau tshuab, nqus nqus tsev vacuum, kas fes li los yog khoom noj khoom haus processor. Nrog rau qhov teeb meem ntawm no hom ntawm motors tiv zoo, tshwj xeeb tshaj yog txij thaum lawv yog suab tsis muaj lwm txoj kev.

Txuas ib zaug xwb-theem induction lub cev muaj zog muaj nws tus kheej cov yam ntxwv uas ua los ntawm cov specifics ntawm tus tsim. Qhov tseeb yog hais tias tus pib kauj yog tsis tsim rau lub lag luam nruam. Khiav cov cav tov ua nyob rau hauv lub luv luv-term lub lag luam. Tom qab ua hauj lwm txheej angular ceev saw ntxiv excitation teb yuav tsum tau qhib, txwv tsis pub nws yuav txaus ntshai overheating thiab tau ua hauj lwm. Pib lub sij hawm, feem ntau yog tsis muaj ntau tshaj li peb mus rau tsib seconds. Disconnection yuav ua tau yog manually (tsuas tso lub khawm "Start") los yog txiav (siv cov interrupter timer relays). Qhov tseem sophisticated systems yog centrifugal pab kiag li lawm tsim rau disabling lub koob kauj ntawm lub caij thaum cov asynchronous ib leeg-theem lub cev muaj zog nce mus txog ib tug nyob ceev.

Nyob rau hauv tas li ntawd mus rau lub ntxiv winding thiab pib khawm muaj lwm lub caij tsim nyog yuav ua rau ib leeg-theem induction lub cev muaj zog rau tig. Kev twb kev txuas tswvyim muab ib tug series kev twb kev txuas nrog ib tug inductance Circuit Court, kom ntseeg tau theem ua haujlwm. Feem ntau, qhov no capacitor, thaum lub sij hawm cov zaj uas los ntawm lub fais tam sim no vector hloov cov kev taw qhia uas muaj kev sib hwm mus rau lub voltage vector.
