Chifukwa chiyani ma rotor amoto amakhala ndi mipata yotseka?

Ndi kufunafuna kosalekeza kwa injini zamagalimoto, ma rotor otsekeka amazindikiridwa pang'onopang'ono ndi opanga magalimoto. Zamagawo atatu asynchronous motors, chifukwa cha kukhalapo kwa stator ndi rotor grooves, kuzungulira kudzatulutsa kutaya kwa pulsation. Ngati ozungulira utenga chatsekedwa kagawo, ogwira mpweya kusiyana ndi adzafupikitsidwa, ndi pulsation wa mpweya kusiyana maginito wafooketsedwa, motero kuchepetsa masangalalo kuthekera ndi harmonic maginito kutayika, amene amathandiza patsogolo ntchito galimoto.
Chiwongolero cha Arch ndi gawo lofunikira la rotor yotsekedwa, ngati mtundu womwewo wa rotor slot, kusankha kwa kutalika kosiyanasiyana kwa mlatho kudzakhala ndi magawo osiyanasiyana pamagalimoto. Kutsekedwa kagawo kozungulira stacking chifukwa palibe kagawo wosaoneka, mwaukhondo kufufuza n'kovuta, zosavuta kuoneka chobisika macheka vuto, kuonjezera zinthu zosalamulirika.

Kugwiritsa ntchitorotor chatsekedwa kagawo, pamene kuchepetsa kutayika kosokera ndi kugwiritsira ntchito chitsulo kwa injini, kumawonjezera kutsekemera kwa rotor, zomwe zimapangitsa kuchepa kwa mphamvu, kuwonjezeka kwa stator katundu wamakono, kuwonjezeka kwa stator; kuyambira ma torque ndi kutsika kwaposachedwa, kuchuluka kwa zotuluka kumawonjezeka. Chifukwa chake, mukamagwiritsa ntchito kagawo kotsekeka, kusintha kwamitundu yosiyanasiyana ya magwiridwe antchito kuyenera kuganiziridwa nthawi imodzi kuti muwongolere magwiridwe antchito onse agalimoto.

Kodi induction motor ndi chiyani?

Motor induction imatanthawuza mtundu wa stator ndi rotor ndi electromagnetic induction, inductance current mu rotor kuti izindikire electromechanical energy conversion motor. Ma stator a induction motor amakhala ndi magawo atatu: stator core, stator winding ndi mpando. Chozunguliracho chimakhala ndi rotor core, rotor windings ndi rotor shaft. Pakatikati pa rotor, yomwe ilinso gawo lalikulu la maginito, nthawi zambiri imapangidwa ndi zitsulo zachitsulo za silicon zokhala ndi makulidwe a 0.5mm, ndipo pachimake chimakhazikika pa shaft yozungulira kapena bulaketi ya rotor. Rotor yonse imakhala ndi mawonekedwe a cylindrical.

Thekuzungulira kwa rotoramagawidwa m'mitundu iwiri: khola ndi wirewound. Nthawi zonse, liwiro la rotor la induction motor nthawi zonse limakhala lotsika pang'ono kapena lalitali kuposa liwiro la maginito ozungulira (liwiro la synchronous), motero ma induction motors amatchedwanso "asynchronous motors". Pamene katundu wa induction motor akusintha, liwiro la rotor ndi kusinthasintha kwa kusinthako kumasintha moyenerera, kotero kuti mphamvu yamagetsi, yamakono ndi maginito amagetsi mu kondakitala wa rotor idzasintha mogwirizana ndi zosowa za katundu. Kutengera kusinthasintha kwabwino kapena koyipa komanso kukula kwa ma induction motor, pali mitundu itatu ya magwiridwe antchito: mota, jenereta ndi ma brake amagetsi.
