Yuav ua li cas yog asynchronous tshuab thiab cov uas yees ua lawv

Yog vim li cas hais tias asynchronous tshuab yog dav siv, yog lub simplicity ntawm lawv tsim, kev cia siab thiab manufacturability. Lub applicability ntawm lub peb-theem thiab ib theem network, muaj ntau ntau yam ntawm daim ntawv Tuition Waiver, yooj yim uas hloov cov kev coj ntawm kev sib hloov - tag nrho cov no ua rau lawv indispensable li lub ntsiab ntau yam ntawm pab kiag li lawm, xws li cov cav tov thiab conveying systems.

Ib tug tseem ceeb kom zoo dua enjoyed los ntawm asynchronous tshuab, yog lawv cov qib high theem ntawm efficiency.

Cov feem ntau motors - kilomatt, lawv daim ntawv thov yog dav heev, yuav luag txhua txhua industrial enterprise, lawv ua tau ib tug loj ib feem ntawm tus tsav units.

Lub npe ntawm lub asynchronous fais tshuab tau txais vim hais tias ntawm lawv cov angular tshaj tawm nyob rau ntawm tus neeg kho tshuab load rau tus ncej. Lub siab dua tus kuj torque, yog li lawm nws rotates maj mam. Cov lag angular tshaj tawm los ntawm lub rotor los ntawm cov muab kev ceev ntawm lub magnetic teb generated los ntawm tam sim no ntws los ntawm cov stator windings, yog hu ua ris hauv qab. Nws yog xam raws li txoj cai, raws li ib tug txheeb ze tus nqi:

S = (ωn-ωp) / ωn

qhov twg:

ωn - magnetic teb muab ceev, Rev. / min.;.

ωp - rotor ceev, Rev. / min ..

Tus kwv tij qhov tseem ceeb ntawm lub load rau ntawm tus nqi rau ncej qhia nyob rau hauv kev nyob rau hauv uas lub hom ntawm idling S yog zoo pes tsawg.

Tus ntaus ntawv asynchronous tshuab yog tib yam li lwm yam electric tsav los yog generator. Lub puab nto ntawm lub stator yog muab nrog tshwj xeeb grooves, uas yog pw nyob rau hauv lub winding (nyob rau hauv cov ntaub ntawv ntawm peb-theem mov, thiab rau ib theem motors - ob). Lub rotor kuj yooj yim, nws cov qauv tsa ib tug nas tawb, thiab tau shorted windings los yog hu rau rings.

Nyob rau hauv cov ntaub ntawv ntawm ib tug nas-tawb rotor vim inductive pickup los ntawm tam sim no nyob rau hauv lub stator windings ntawm lub rotor electromotive quab yuam tshwm sim raws li txoj cai txhais tes txoj cai. Ces txhua yam yog yooj yim: ob ntas, uas kis tau ib tug hluav taws xob tam sim no, pib nrog txhua lwm yam, thiab muaj yog torque.

Asynchronous tshuab, uas rotor yog muab nrog hu rings khiav lag luam txawm yooj yim hwj chim rau tus rotating winding yog noj ncaj qha los ntawm cov pa roj carbon txhuam. Tej rotors yog hu ua theem.

Ib leeg-theem induction motors muaj ob windings, thiab pib ua hauj lwm, rau generating thawj torque thiab cov rotor angular unwinding mus khiav hauj lwm ceev. Cov motors siv qhov peb theem network yog tsis muaj, piv txwv li, tsav tsheb lub rotating qhov chaw ntawm khoom vaj khoom tsev.

Nyob rau hauv tas li ntawd mus rau lub engine induction yog cov opposite lub hom phiaj machines, generators. Lawv ntaus ntawv yog tshuam zoo sib xws. Rau cov credit ntawm Lavxias teb sab hluav taws xob engineering, peb yuav confidently tham txog ua ntej ntawm peb lub teb chaws nyob rau hauv lub teb ntawm hluav taws xob motors ntawm no hom. MO Dolivo-Dobrovolsky rov qab nyob rau hauv 1889, lub ntiaj teb no tus thawj peb-theem hwj chim thov thiab tau txais ib yam magnetic teb. Niaj hnub nimno asynchronous tshuab tsis txawv los ntawm tus thawj peb-theem motors ntawm tus poj Lavxias teb sab inventor thiab paub txog.
