Asynchronous lub cev muaj zog: tsim thiab apparatus

Peb-theem asynchronous lub cev muaj zog nrog tus nas ncuav tawb twb yees ua rov qab rau hauv 1889, nyob rau 8 Lub peb hlis ntuj, tus naas ej Lavxias teb sab neeg kawm xaij thiab engineer Mikhail Osipovich Dolivo-Dobrovolsky. Twb tau nyob rau cia li ib lub xyoo, lub Kaum Ob Hlis 15, 1890, yog invented thiab patented lub cev muaj zog nrog plam-ntiv nplhaib motors.

Peb-theem asynchronous tsav - ib qho ntawm feem ntau hluav taws xob pab kiag li lawm nyob rau hauv kev ua lag luam. Nws yog yooj yim rau koj khiav lag luam, txhim khu kev qha thiab muaj ib tug ncaj uas tsis muaj nqi. Asynchronous lub cev muaj zog yuav siv sij hawm zoo cuaj caum feem pua ntawm tag nrho cov xov tooj ntawm xyaw thoob ntiaj teb. Nws muaj peev xwm yuav nrhiav tau txhua txhia qhov chaw - los ntawm tus tsim ntawm ib tug pa, ntxuav lub tshuab, mus rau loj industrial khw, tsis hais lub hwj chim. Nws ua ib tug zoo hauj kiv puag ncig nyob rau hauv lub ntiaj teb no kev lag luam.

Asynchronous lub cev muaj zog - ib lub tshuab uas yog tsim los hloov hluav taws xob lub zog mus rau hauv cov neeg kho tshuab zog. "Asynchronous" tsuas txhais tau tias "tsis synchronous". Nws yog to taub hais tias xws li ib tug tshuab lub zaus uas ib yam magnetic teb generated los ntawm cov stator, yuav nco ntsoov yuav ntau dua tus nqi uas rotates lub rooj noj ib feem ntawm lub cev muaj zog - rotor.

Asynchronous lub cev muaj zog muaj ib tug taag ib feem - cov stator thiab lub rooj noj yam ib feem - lub rotor.

Lub stator yog tau koom ua ke los ntawm cov ntawv txheeb ntawm compressed hluav taws xob hlau thiab feem ntau muaj ib tug cylindrical zoo. Lub grooves ntawm cov tub ntxhais yog stacked stator winding yog ua los ntawm winding hlau. Stator windings ntawm ib tug ob peb. Cov ntaub ntawv winding axis feem ntau txav los ntawm lub kaum sab xis ntawm 120 degrees txheeb ze rau txhua tus lwm yam. Lub xaus ntawm cov windings tej zaum yuav nrog nyob rau hauv lub hnub qub los yog delta (nyob ntawm seb uas voltage yog thov).

Lub rotors muaj xws li ib tug tshuab, raws li cov induction lub cev muaj zog, thiab yog cov luv luv-circuited theem.

Tus thawj hom (ib tug luv luv-circuited rotor) - ib tug tseem ceeb uas yog tau koom ua ke los ntawm tooj liab los yog txhuas rods nteg nyob rau ntawd winding. Cov rods yog kev cob cog rua rau thaum xaus rings, thiab lawv cov tsos tsa ib tug nas tawb. Los ntawm txoj kev, yog li no rotor ntaus feem ntau xa mus rau raws li "nas-tawb". Lub rotor yog nyob rau hauv cov ntaub ntawv no dua sau los ntawm hluav taws xob steel los xij, nias thiab ncuav txhuas.

Theem rotor yog feem ntau hu ua lub rotor ris hauv qab lub nplhaib. Nws muaj ib tug peb-theem winding, uas yog ua tau txawv heev los ntawm cov stator windings. Yeej, qhov xaus ntawm lub windings ntawm lub rotor ris hauv qab lub nplhaib (theem) kev cob cog rua nyob rau hauv ib lub hnub qub. Cov dawb xaus yog kev cob cog rua rau lub ris hauv qab ib ncig li. Lub winding Circuit Court yog feem ntau ntxiv ntxiv resistor vim lub xub ntiag ntawm tshwj xeeb txhuam, kev cob cog rua rau lub rings. Xws li ib tug resistor tsub kom lub kuj nyob rau hauv lub rotor Circuit Court, uas muaj txhawb rau ib tug smoother starting thiab txo qhov tseem ceeb inrush tam sim no - nws yog ib qho tseem ceeb heev rau tej tshuab, xws li peb-theem asynchronous motors.
