Lub peb-theem Circuit Court

Lub ntsiab tam sim no system saws tam sim no universally yog peb theem circuits, uas muaj ob peb zoo dua ib leeg-theem.

Peb-theem tam sim no hu ua peb theem currents generated los ntawm peb cov electromotive rog muaj tib lub amplitude thiab zaus tab sis txav nrog kev sib hwm rau txhua lwm yam nyob rau hauv theem los ntawm 120⁰ los yog thaum lub sij hawm ib tug thib peb lub sij hawm lub sij hawm.

Txhua cais Circuit Court, xws li ib tug peb-theem system yog hais tias kom tsis txhob muaj cov theem.

Theem tam sim no, uas yog nqa tawm peb-theem Circuit Court yuav tsum tau ua los ntawm combining peb ntawm cov tib generator, muab ib tug ib-theem alternating tam sim no, rotors, uas yog nyob rau hauv ib tug taag txoj hauj lwm, yog rigidly txuas mus rau txhua lwm yam thiab tsis hloov lawv txoj hauj lwm thaum lub sij hawm kev sib hloov. Nyob rau hauv no generator stator windings yog unfolded los ntawm txhua lwm yam los ntawm 120⁰ nyob rau rotor sab. Nyob rau hauv tej yam, nws yog heev pom tseeb hais tias electromotive quab yuam ntawm lub thib ob generator yuav tseem yuav nyob hauv lawv cov kev hloov nyob rau hauv kev sib raug zoo mus rau tus thawj generator rau 120⁰, piv txwv li lub nqi siab tshaj plaws ntawm lub electromotive quab yuam ntawm cov tib cov kev taw qhia nyob rau hauv lub thib ob generator yuav tuaj tom qab tag nrho cov generator rotor yuav tig rau 120⁰. Lub electromotive quab yuam ntawm peb generator yuav kuj yuav raug ncua txheeb ze mus rau lub thib ob generator 120⁰.

Tab sis xws li ib txoj kev uas ua tam sim no, uas yog peb theem Circuit Court, yog tsis kev lag kev luam zaum thiab technically yooj yim. Ntau yooj yim rau peb stator windings yog kev cob cog rua nyob rau hauv ib lub pob. Xws li ib tug generator yog hu ua tus generator theem tam sim no.

Yog li, lub stator alternator tam sim no muaj peb windings (hu ua generator theem), nyob 120⁰ moog txheeb ze rau txhua tus lwm yam. Lub rotor yog ib tug peb-theem tam sim no generator nrog ib tug rotor structurally zoo tib yam nkaus xwb-theem AC generator.

Thaum lub sij hawm kev sib hloov ntawm lub rotor windings nyob rau hauv tag nrho cov zoo ib yam nyob rau hauv zaus thiab amplitude ntawm lub electromotive quab yuam, tab sis lawv tsis txhij mus txog lawv cov nyiaj pab ntau tshaj. Piv txwv tias yog tias cov nyiaj pab ntau tshaj electromotive dag zog yuam yog generated nyob rau lub sij hawm ntawm lub tso cai ntawm qhov chaw ntawm lub sab qaum teb ncej ntawm lub rotor thaum pib ntawm winding, nws yog ib qho yooj yim mus pom tias lub siab tshaj plaws electromotive quab yuam ntawm cov tib cov kev taw qhia nyob rau hauv lub thib ob kauj yuav tuaj tom qab txoj kev sib hloov ntawm lub rotor rau 120⁰, thiab lub thib peb - tom qab txoj siav 240⁰ txheeb ze mus rau tus thawj.

Txuas mus rau ib tug sab nraud Circuit Court txhua theem generator, peb muab tau cov peb theem tam sim no Circuit Court muaj tsis muaj sib thooj, tsis muaj hluav taws xob sib txuas, nyob rau txhua cais Circuit Court currents nyob rau tib lub lawv tsis kam yuav ua ncaj nyob rau hauv amplitude tab sis txav nyob rau hauv theem txheeb ze rau txhua tus lwm yam kuj nyob rau ntawm 120⁰.

Yuav kom txuas xws li ib tug generator mus rau ib qho sab nraud Circuit Court, yuav tsum rau ntawm tej. Yuav kom txo tau cov naj npawb ntawm cov xov hlau uas mus rau cov sab nraud Circuit Court, nws yog tsim nyog mus cuag lub receiver kauj thiab generator interconnected rau daim ntawv electrically coupled rau lub peb-theem system. Qhov no kev twb kev txuas yuav ua tau nyob rau hauv ob txoj kev sib txawv: ib daim duab peb sab thiab ib lub hnub qub.

Ob tebchaw ua rau nws tau mus cawm cov ntaub ntawv uas nyob rau hauv cov kis ntawm cov tib peev xwm los ntawm peb ywj siab peb-theem generators.

Peb-theem circuits ua nws tau los mus tsim ib tug yooj yim thiab yooj yim rau cov ntaus ntawv mus rau koj khiav lag luam cov hluav taws xob lub cev muaj zog, uas yog hu ua asynchronous. Nws ntaus ntawv raws li nyob rau hauv daim ntawv thov ntawm cov rotating magnetic teb. Nyob rau hauv lub nyuaj cov ntaub ntawv, ib tug sib nqus teb yuav tsum tau los ntawm yam tus horseshoe magnet.

Yog hais tias lub teb yog muab tso rau hauv ib yam kaw neeg xyuas pib, fastened mus rau lub axis, lub magnetic teb nyob rau hauv nws cov kev sib hloov kev sib tshuam sab Circuit Court neeg xyuas pib yuav induce ib electromotive quab yuam nyob rau ntawd induction uas generates ib tug induction tam sim no nyob rau hauv no lub voj kaw. Qhov no tam sim no interacting nrog lub magnetic teb ntawm lub rotating magnet kauj yuav tig. puv cov kev taw qhia kev sib hloov ntawm yog txiav txim los ntawm kev siv rau sab laug tes txoj cai.

Peb theem motors yog muaj li ntawm ob qhov chaw: ib yam ib feem - lub rotor thiab lub chaw - lub stator.

Lub rotating magnetic teb yog generated nyob rau hauv lub cav tsis yog los ntawm cov neeg kho tshuab kev sib hloov ntawm lub magnetic tug, thiab nyob ib tug khiav ntawm alternating tam sim no ntawm tsau-theem stator windings.

Peb-theem circuits tau tsim los ntawm ib tug ntawm cov loj tshaj hluav taws xob engineers ntawm lub XIX thiab thaum ntxov XX caug xyoo. - Lavxias teb sab engineer MO Dolivo-Dobrovolsky (1862-1919). Qhov no system tau qhib zoo kawg li lub sij hawm kom muaj kev siv hluav taws xob. Qhov tseem ceeb tshaj yog:

• savings nyob rau hauv xov kab txuas qhov chaw nres tsheb rau cov neeg siv khoom;
• tau yam magnetic teb thov nyob rau hauv peb-theem motors.
