Chifukwa chiyani ma motors ambiri a zida zapakhomo amagwiritsa ntchito ma motors okhala ndi mithunzi, ndipo ubwino wake ndi wotani?

Galimoto yamtundu wa shaded ndi njira yosavuta yodzipangira yokha ya AC single-phase induction motor, yomwe ndi galimoto yaing'ono ya gologolo, yomwe imazunguliridwa ndi mphete yamkuwa, yomwe imatchedwanso mphete yamtengo wapatali kapena mphete yamtengo.Mphete yamkuwa imagwiritsidwa ntchito ngati mafunde achiwiri a injini.Zodziwika bwino za mota ya shaded-pole ndikuti mawonekedwe ake ndi osavuta, palibe chosinthira cha centrifugal, kutayika kwamphamvu kwa mota ya shaded-pole ndi yayikulu, mphamvu yamagalimoto ndiyotsika, ndipo torque yoyambira nayonso ndiyotsika kwambiri. .Zapangidwa kuti zikhalebe zazing'ono komanso kukhala ndi mphamvu zochepa.Liwiro la ma motors ndilofanana ndi kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito pamagetsi, zomwe nthawi zambiri zimagwiritsidwa ntchito kuyendetsa mawotchi.Ma motors a shaded-pole amangozungulira mbali ina yake, mota siyingazungulire kwina, kutayika kopangidwa ndi ma coil a shaded-pole, mphamvu yamagalimoto ndiyotsika, ndipo kapangidwe kake ndi kosavuta, ma mota awa amagwiritsidwa ntchito kwambiri pamafani apanyumba. ndi zida zina zazing'ono.

Momwe Shaded Pole Motor Imagwirira Ntchito

Motor Shaded-pole ndi AC single-gawo induction motor.Mapiringidwe othandizira amapangidwa ndi mphete zamkuwa, zomwe zimatchedwa shaded-pole coil.Zomwe zili mu koyiloyo zimachedwetsa gawo la maginito osinthasintha pagawo la maginito kuti apereke mphamvu ya maginito yozungulira.Njira yozungulira imachokera pamtengo wopanda mthunzi.ku mphete yamtengo.

Ma coil (mphete) okhala ndi mithunzi amapangidwa kuti nsonga ya maginito isunthike kuchoka kumtunda wamtengo waukulu, ndipo ma coil a maginito ndi ma coil owonjezera okhala ndi mithunzi amagwiritsidwa ntchito kuti apange mphamvu yozungulira yofooka.Pamene stator ipatsidwa mphamvu, mphamvu ya maginito ya matupi amtengowo imapanga magetsi muzitsulo zamtengo wapatali, zomwe zimakhala ngati mafunde achiwiri a thiransifoma.Pakalipano pamapiritsi achiwiri a thiransifoma simalumikizidwa ndi mafunde apano mumayendedwe oyambira, ndipo kusinthasintha kwa maginito amtengo wonyezimira sikumalumikizidwa ndi maginito amtundu waukulu.

Mu injini yamtundu wa shaded, rotor imayikidwa mu c-core yosavuta, ndipo theka la mtengo uliwonse umaphimbidwa ndi koyilo yamthunzi yomwe imapanga pulsating flux pamene njira yosinthira ikudutsa pa koyilo yoperekera.Pamene kusinthasintha kwa maginito kupyolera mu koyilo ya shading kumasintha, magetsi ndi zamakono zimapangidwira mu coil yamtengo wapatali, zomwe zimagwirizana ndi kusintha kwa maginito kuchokera ku koyilo yamagetsi.Chifukwa chake, kusinthasintha kwa maginito pansi pa koyilo yamithunzi kumalepheretsa kutulutsa kwa maginito mu koyilo yonseyo.Kuzungulira kwakung'ono kumapangidwa mu maginito othamanga ndi rotor, kotero kuti rotor imazungulira.Chithunzi chotsatira chikuwonetsa mizere ya maginito yomwe imapezedwa ndi kusanthula kwazinthu zomaliza.

Shaded Pole Motor Structure

Ma rotor ndi masitima apamtunda ochepetsera omwe amalumikizidwa amazingidwa mu aluminiyamu, mkuwa kapena nyumba yapulasitiki.Rotor yotsekedwa imayendetsedwa ndi maginito kudzera m'nyumba.Magiya oterowo amakhala ndi shaft yomaliza kapena zida zomwe zimayenda kuchokera ku 600 rpm mpaka 1 pa ola./ 168 zosintha (zosintha kamodzi pa sabata).Popeza nthawi zambiri palibe njira yoyambira yoyambira, rotor ya mota yomwe imayendetsedwa ndi ma frequency pafupipafupi iyenera kukhala yopepuka kwambiri kuti ifikire liwiro logwira ntchito mkati mwaulendo umodzi wa ma frequency operekera, rotor ikhoza kukhala ndi khola la gologolo, kotero kuti injini imayamba ngati injini yolowera, pomwe rotor ikakokedwa kuti ilumikizane ndi maginito ake, palibenso mphamvu yamagetsi mu khola la agologolo ndipo chifukwa chake sichimagwiranso ntchito, kugwiritsa ntchito ma frequency control control kumathandizira kuti pakhale mota wa shaded pole. kuyamba pang'onopang'ono ndikupereka torque yambiri.

Galimoto yamtengo wapataliliwiro

Shaded pole galimoto liwiro zimadalira mamangidwe a galimoto, liwiro synchronous (liwiro limene stator maginito azungulira) zimatsimikiziridwa ndi pafupipafupi athandizira AC mphamvu ndi chiwerengero cha mitengo mu stator.Mizati yochulukira ya koyiloyo, kuthamanga kwapang'onopang'ono, kuthamanga kwamagetsi komwe kumagwiritsidwa ntchito, kukwezeka kwa liwiro lofananira, ma frequency ndi kuchuluka kwa mitengo sikusintha, liwiro la synchronous la 60HZ motor ndi 3600, 1800, 1200. ndi 900rpm.Zimatengera kuchuluka kwa mizati mu kapangidwe koyambirira.

Pomaliza

Popeza torque yoyambira ndi yotsika ndipo siyingapangitse torque yokwanira kutembenuza zida zazikulu, ma mota amtundu wa shaded amatha kupangidwa m'magawo ang'onoang'ono, pansi pa ma watts 50, otsika mtengo komanso osavuta kwa mafani ang'onoang'ono, kuzungulira kwa mpweya ndi ntchito zina zotsika.Kuthamanga kwa injini kumatha kuchepetsedwa ndi kachitidwe kambiri kuti muchepetse matani apano ndi ma torque, kapena posintha kuchuluka kwa ma koyilo agalimoto.
