Magawo atatu amagetsi amagetsi amakhala ndi zomangamanga zolimba ndi magawo osiyanasiyana komanso makina ogwirira ntchito.Masiku ano, ma motors a 3-phase ac induction motors amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana azamalonda ndi malonda chifukwa cha liwiro lawo komanso torque.Kumvetsetsa magawo osiyanasiyana a 3 phase motor ndikofunikira kuti musankhe zoyenera kugwiritsa ntchito.Motor 0ffers osiyanasiyana ma motors atatu magawo osiyanasiyana kuchokera 1500rpm-3000rpm.
Chithunzi 1: 3 gawo la magalimoto
Mu bukhu loyambilirali, tikambirana magawo atatu agalimoto ndi ntchito zawo.
3 gawo motor Parts:
Ma motors atatu ndi otchuka chifukwa cha zomangamanga zawo zolimba komanso zodalirika.Tiyeni timvetse 3 gawo motor mbali kwambiri;
Stator:
Mu magawo atatu a motors, stator ndiye gawo lofunikira kwambiri.Ndilo gawo loyima lomwe limapangitsa kuti rotor isunthire mbali ya maginito.Gawo ili la 3 phase motor limakhalanso ndi magawo otsatirawa;
Pakatikati:
Mkati mwa stator, mawonekedwe a laminated alipo, omwe amadziwika kuti stator core.Pakatikati pa stator ili ndi mipata yolumikizana kutengera kuchuluka kwa mitengo yamagetsi yamagetsi.Ma motors ena ali ndi mizati 2 ndi mipata 3 kapena mizati 3 ndi mipata 4, ndi zina zotero. Liwiro la galimotoyo ndi losiyana kwambiri ndi chiwerengero cha mitengo.Ngati chiwerengero cha mizati ndi chachikulu, liwiro adzakhala ochepa ndi mosemphanitsa.
Stator frame:
Chophimba chakunja cha stator chimatchedwa stator frame.Chojambula cha stator chimapangidwa ndi zinthu zapamwamba kwambiri ndi 100% zitsulo zosapanga dzimbiri kuti ziteteze ziwalo zamkati.Zimatsimikiziranso moyo wautali komanso kukhazikika.
Mapiritsi a Stator:
Kuzungulira kwa stator kumapanga maginito maginito mu stator.Magawo atatuwa amasangalala akalumikizidwa ndi magetsi ndikuyamba kupanga maginito.Ma stator windings ndi insulated ndi resistive kuonetsetsa chitetezo mu zinthu zoipa.
Rotor:
Rotor ndi gawo lina lofunikira mu magawo atatu a mota.Chigawo chosuntha chomwe chimazungulira kumbali ya maginito chimatchedwa rotor.Rotor ya atatu gawo motors amanyamula panopa kusuntha kutsinde.Magawo atatu agalimoto amagawidwanso m'magulu awiri akulu kutengera kapangidwe ka rotor;
Mphete kapena mtundu wa bala:
Rotor ya mtundu wa bala nthawi zambiri imakhala ndi zida zopindika komanso mphete zoterera.Ma motors awa amapereka torque yayikulu komanso yosasinthika;chifukwa chake, ma motors awa amagwiritsidwa ntchito kwambiri m'mafakitale olemetsa kwambiri chifukwa amalola kukana kwakunja kuti achepetseko pano.
Chithunzi 2: Rotor ya slip-ring induction motor
Squirrel khola lamoto wozungulira:
Galimoto ya squirrel cage ndiyo yomwe imagwiritsidwa ntchito kwambiri ndi 3-phase induction motor chifukwa cha kapangidwe kake kosavuta ka khola.Rotor yamtundu wa khola imakhala ndi aluminiyamu kapena mipiringidzo yamkuwa yokhazikika mkati mwa mipata.Mtundu uwu wa mota wa magawo atatu umagwiritsidwa ntchito pazamalonda otsika komanso zapakhomo.
Bokosi lokwerera:
Bokosi la terminal limadziwikanso mu magawo atatu amagetsi.Bokosi la terminal limapereka mphamvu ya magawo atatu kudzera pamagetsi akunja.Ma stator windings amalumikizidwa ku terminal box kudzera pa delta kapena nyenyezi.
Wotsatsa:
Pakuchepetsa kutentha ndi kuziziritsa, chowotcha chimawonedwa ngati gawo lalikulu la ma motors 3 phase induction motors.Imasunga kutentha ndikuziziritsa mbali zina zamkati za 3 phase induction motor.
Motor imapereka ma motors apamwamba a OEM, ma motors amagetsi agawo limodzi, ndi ma motors amakampani padziko lonse lapansi.
Pomaliza:
Kumvetsetsa magawo atatu agalimoto amakupatsirani lingaliro lambiri la momwe amagwirira ntchito, kuchuluka kwake, ndi magwiridwe antchito.Magawo onse a 3 phase induction motors amathandizira kuti apereke chidziwitso chosavuta komanso cholondola.Ma motors awa adapangidwa mwapadera kuti azipereka torque yayikulu komanso magwiridwe antchito pamtengo wotsika mtengo.Mutha kulumikizana nafe kuti mupeze ndemanga zaulere komanso kufunsa.Thandizo lathu lamakasitomala limagwira ntchito mosadodometsedwa kuti tithane ndi nkhawa zanu.
Mafunso omwe amafunsidwa pafupipafupi - magawo atatu agalimoto
1. Kodi 3 phase motor ndi chiyani?
Galimoto yolowetsa magawo atatu ndi mota ya AC yokhala ndi zochititsa chidwi.Ma motors a magawo atatu ndi injini zoyambira zokha, zogwira mtima, komanso zolimba zamafakitale.Ma motors awa amagwira ntchito pa mfundo ya electromagnetism ndipo safuna ma capacitor kapena magetsi akunja kuti azitha kuzungulira koyambirira.Ma motors awa amapereka mphamvu zochulukirapo 1.5x kuposa ma mota agawo limodzi.Komabe, ndikofunikira kumvetsetsa magawo atatu agalimoto, mfundo zogwirira ntchito, ndikugwiritsa ntchito musanagule.
2. Kodi magawo atatu agalimoto amawononga ndalama zingati?
Magawo a 3 phase induction motors amapangidwa ndi 100% coil yamkuwa ndi chitsulo chosapanga dzimbiri kuti akhale ndi moyo wautali.Ma motors awa ndi okwera mtengo kuposa ma mota agawo limodzi chifukwa cha magawo atatu agalimoto ndi magwiridwe antchito.Mtengo wa magawo atatu oyendetsa magalimoto amasiyana malinga ndi magawo angapo monga ma voltage osiyanasiyana, ma frequency, rpm, ndi mtundu wa zomangamanga.
3. Ndi mbali ziti zosuntha zomwe zatha mu ma motors olowetsa magawo atatu?
Zigawo zosuntha za 3 phase induction motor zomwe zatha ndi zokhala ndi mphete zoterera.3-phase induction motor ili ndi zotengera ziwiri zozungulira shaft.Nthawi zina, mayendedwe amatha chifukwa cha kusamalidwa kochepa, kutsitsa mochulukira, ndi zolakwika pakuyika.Kuphatikiza apo, mu ma slip-ring induction motors, mbali za 3 phase motor zomwe zimatha ndi mphete zoterera.
