Ndi kuchulukitsidwa kwa magetsi osinthika pafupipafupi, vuto la injini yoyambira limathetsedwa mosavuta, koma kwamagetsi wamba, kuyambira kwa gologolo-cage rotor asynchronous motor nthawi zonse kumakhala kovuta.Kuchokera pakuwunika koyambira ndi kuthamanga kwa injini ya asynchronous, zitha kuwoneka kuti kuti muonjezere torque yoyambira ndikuchepetsa zomwe zikuchitika poyambira, kukana kwa rotor kumafunika kukhala kwakukulu;pamene galimoto ikuyenda, kuti muchepetse kugwiritsa ntchito mkuwa wa rotor ndikuwongolera kuyendetsa bwino kwagalimoto, kukana kwa rotor kumafunika kukhala kochepa;izi zikumveka zotsutsana.

Pakuti chilonda rotor galimoto, popeza kukana akhoza chikugwirizana mu mndandanda pa chiyambi, ndiyeno kudula pa nthawi ya ntchito, chofunika ichi bwino anakumana.Komabe, kapangidwe ka chilonda asynchronous motor ndizovuta, mtengo wake ndi wokwera, ndipo kukonza kumakhala kovuta, chifukwa chake kugwiritsa ntchito kwake kumakhala kochepa pamlingo wina;Resistors, pamene akuthamanga dala ndi resistors ang'onoang'ono.Malo ozama ndi ma motors a gologolo ozungulira awiri ali ndi ntchito yoyambira iyi.Lero, Ms. nawo kulankhula za deep slot rotor motor.

Makina ozama asynchronous motor

Pofuna kulimbitsa khungu, mawonekedwe a groove asynchronous motor rotor ndi ozama komanso opapatiza, ndipo chiŵerengero cha kuya kwa groove ndi m'lifupi mwake ndi 10-12.Zomwe zikuchitika pano zikadutsa mu bar ya rotor, kutulutsa kwa maginito komwe kumadutsa pansi pa bar kumakhala kochulukirapo kuposa komwe kumadutsana ndi gawo la notch.Choncho, ngati kapamwamba amaonedwa kuti ogaŵikana angapo ang'onoang'ono Ngati kondakitala olumikizidwa mu kufanana, kondakitala ang'onoang'ono pafupi ndi pansi pa kagawo ndi zambiri kutayikira reactance, ndi kuyandikira kagawo, ang'onoang'ono kutayikira anachita.

 

Poyambira, chifukwa mafupipafupi a rotor panopa ndi apamwamba ndipo kutayikira reactance ndi lalikulu, kugawa panopa pa kondakitala yaing'ono iliyonse kudzadalira reactance kutayikira, ndi yaikulu reactance kutayikira, ang'onoang'ono kutayikira panopa.Mwa njira iyi, pansi pa mphamvu zomwezo zomwe zimapangitsidwa ndi kusinthasintha kwakukulu kwa maginito a mpweya wa mpweya, kachulukidwe kameneka mu kapamwamba pafupi ndi pansi pa kagawo kamakhala kakang'ono kwambiri, ndipo pafupi ndi kagawo, kuwonjezereka kwamakono. kachulukidwe.

Chifukwa cha zotsatira za khungu, pambuyo poti zambiri zapano zikukanikizidwa kumtunda wa kalozera wotsogolera, ntchito ya kalozera pansi pa groove ndi yaying'ono kwambiri.Pezani zofunikira za kukana kwakukulu poyambira.Pamene galimoto yayamba ndipo galimoto ikuyenda bwino, popeza mafupipafupi a rotor panopa ndi otsika kwambiri, kutayikira kwa mafunde a rotor kumakhala kochepa kwambiri kusiyana ndi kukana kwa rotor, kotero kugawidwa kwa magetsi muzitsulo zomwe tatchulazi zidzakhala makamaka. kutsimikiziridwa ndi kukana.

 

Popeza kukana kwa woyendetsa kakang'ono kalikonse ndi kofanana, zomwe zili mu bar zidzagawidwa mofanana, kotero kuti khungu la khungu limatha, ndipo kukana kwa rotor bar kumakhala kochepa, pafupi ndi DC kukana.Zitha kuwoneka kuti kukana kwa rotor pakugwira ntchito kwanthawi zonse kumangotsika, potero kukhutiritsa zotsatira zochepetsera kugwiritsa ntchito mkuwa ndikuwongolera bwino.

Kodi khungu limakhudza bwanji?Zotsatira za khungu zimatchedwanso zotsatira za khungu.Pamene njira yosinthira ikudutsa pa kondakitala, yamakono idzayang'ana pamwamba pa kondakitala ndikuyenda.Chodabwitsa ichi chimatchedwa khungu effect.Pamene magetsi kapena magetsi akuyenda mu conductor okhala ndi ma electron apamwamba kwambiri, amasonkhana pamwamba pa kondakitala wathunthu m'malo mogawidwa mofanana m'madera ozungulira a conductor yonse.

Chikopa cha khungu sichimangokhudza kukana kwa rotor, komanso kumakhudzanso kutulutsa kwa rotor.Kuchokera panjira ya kutayikira kwa slot, zitha kuwoneka kuti zomwe zikudutsa pa kokondakita yaying'ono zimangotulutsa kutuluka kwamadzi kuchokera pa kokondakita yaying'ono kupita ku notch, ndipo sikutulutsa kutuluka kwamadzi kuchokera kwa kokondakita yaying'ono mpaka pansi. kagawo.Chifukwa chomalizacho sichimalumikizidwa ndi panopo.Mwanjira iyi, chifukwa cha kukula komweko kwapano, pafupi ndi pansi pa kagawo, kutulutsa kwamadzi kumapangidwanso, ndipo kuyandikira kutseguka kwa slot, kutulutsa kocheperako kumapangidwa.Zitha kuwoneka kuti mawonekedwe a khungu akamafinya zomwe zikuchitika mu bar kupita ku notch, kagawo kakang'ono ka kutayikira kwa maginito komwe kamapangidwa ndi komweko kumachepa, motero kutayikira kwa slot kumachepa.Chifukwa chake mawonekedwe a khungu amawonjezera kukana kwa rotor ndikuchepetsa kutayikira kwa rotor.

Mphamvu ya khungu zotsatira zimadalira pafupipafupi wa rotor panopa ndi kukula kwa kagawo mawonekedwe.Kukwera kwafupipafupi, kuzama kwa mawonekedwe a slot, komanso kufunikira kwa khungu.Rotor yemweyo wokhala ndi ma frequency osiyanasiyana amakhala ndi zotsatira zosiyana za khungu, ndipo chifukwa chake magawo a rotor adzakhalanso osiyana.Pachifukwa ichi, kukana kwa rotor ndi kutayikira pakugwira ntchito moyenera ndikuyambira kuyenera kuzindikirika bwino ndipo sikungasokonezeke.Pafupipafupi, zotsatira za khungu la deep groove rotor ndi zamphamvu kwambiri, koma zotsatira za khungu zimakhalanso ndi chikoka pamtundu wamba wa gologolo khola rotor.Chifukwa chake, ngakhale kwa rotor ya gologolo yokhala ndi mawonekedwe wamba, magawo a rotor poyambira ndikugwira ntchito ayenera kuwerengedwa mosiyana.

The rotor kutayikira reactance ya deep slot asynchronous motor, chifukwa mawonekedwe a rotor slot ndi ozama kwambiri, ngakhale amachepetsedwa ndi chikoka cha khungu, akadali wamkulu kuposa wamba wamba agologolo khola rotor leakage reactance pambuyo kuchepetsa.Chifukwa chake, mphamvu yamagetsi ndi torque yayikulu ya motor slot yakuya ndizotsika pang'ono kuposa zamagalimoto wamba agologolo.
