Peb -Phase Asychronous Motor Structure

Lub hauv paus qauv ntawmpeb theem asychronous lub cev muaj zogmuaj peb yam: sib nqus Circuit Court, hluav taws xob Circuit Court thiab mechanical Cheebtsam.

Lub tshuab hluav taws xob sib nqus suav nrog ob hom hlau cores; stator thiab rotor cores ua haujlwm tib lub hom phiaj.

Cov hluav taws xob hluav taws xob muaj cov windings, qhov txhab nrog cov xov tooj cua insulated.

Cov khoom siv tshuab muaj ntau yam khoom: kawg npog, rotating shafts thiab bearings.

Cov kiv cua thiab cov kiv cua shrouds ua kom sov dissipation; qhov sib txawv ntawm huab cua muaj qhov dav ruaj khov.

Cov ntsiab lus tseem ceeb

Txawm hais tias muaj ntau hompeb theem asynchronous lub cev muaj zog(xws li lub qhov txhab-rotor motors thiab squirrel-cage motors), lawv cov qauv yooj yim yog tib yam, feem ntau muaj peb ntu: lub tshuab hluav taws xob sib nqus, hluav taws xob hluav taws xob thiab cov khoom siv tshuab.

Sib nqus Circuit Court: suav nrog stator core thiab rotor core.

Hluav taws xob Circuit Court: suav nrog stator winding thiab rotor winding.

Mechanical ib feem: nrog rau ncej, terminals, ncej, bearings, thiab lwm yam.

Lus ceeb toom phooj ywg

Lub thawv davhlau ya nyob twg yog ib qho tseem ceeb ntawm kev sib txuas ntawm lub cev muaj zog windings rau cov khoom siv hluav taws xob sab nraud. Nyob rau hauv lub thawv davhlau ya nyob twg, muaj lub rooj tsav xwm davhlau ya nyob twg uas 6 xaim kawg ntawm peb -theem windings tau teem rau hauv kab sab saud thiab qis. Feem ntau, peb -theem windings txuas nrog hauv lub hnub qub lossis delta configuration.

Qhov sib txawv ntawm huab cua ntawm stator thiab rotor feem ntau yog 0.2-2 hli. Qhov loj ntawm qhov sib txawv ntawm huab cua muaj qhov cuam tshuam loj rau kev ua haujlwm ntawm kev ua haujlwmpeb theem asynchronous lub cev muaj zog. Qhov loj dua qhov sib txawv ntawm huab cua, qhov loj dua qhov excitation tam sim no muab los ntawm daim phiaj hluav taws xob, thiab qhov qis zog ntawm cosΦ. Txhawm rau txhim kho qhov zoo ntawm lub zog, qhov sib txawv ntawm huab cua yuav tsum tsawg li tsawg tau; Txawm li cas los xij, vim qhov yuav tsum tau ua los ua ke thiab lwm yam laj thawj, qhov sib txawv ntawm huab cua tsis tuaj yeem me me dhau.
