N'chifukwa chiyani mavuto amenewa nthawi zonse zimachitika pa injini rotor?

Pazolephera zazinthu zamagalimoto, gawo la stator nthawi zambiri limayambitsidwa ndi mafunde. Gawo la rotor ndiloyenera kukhala lopangidwa ndi makina. Kwa ma rotors a bala, izi zimaphatikizaponso kulephera kwa mapindikidwe.

Poyerekeza ndi ma motors ozungulira mabala, ma rotor opangidwa ndi aluminiyamu sakhala ndi vuto, koma vuto likangochitika, ndizovuta kwambiri.

Choyamba, popanda chitetezo overspeed, chilonda rotor ndi zambiri kukhala ndi vuto dontho phukusi, ndiye mapeto a yozungulira yokhotakhota ndi kwambiri radially olumala, amene n'kutheka kuti kusokoneza mapeto a stator mapitiriro, ndiyeno chifukwa. makina onse okhotakhota kuti awotche ndi kupanikizana pamakina. Chifukwa chake, kuthamanga kwa mota ya chilonda sikungakhale kokwera kwambiri, ndipo liwiro la synchronous nthawi zambiri limakhala 1500 rpm kapena kuchepera.

Chachiwiri, rotor ya aluminiyamu yotayira imakhala ndi zovuta zapanyumba kapena zonse. Ngati palibe vuto ndi kapangidwe kake, ndichifukwa choti ma aluminiyamu otayidwa samakumana ndi kapangidwe kake, rotor ili ndi mipiringidzo yosweka kwambiri kapena yopyapyala, ndipo mota imakhala ndi kutentha kwanuko kapena kwakukulu ikamayenda. Zikavuta kwambiri, pamwamba pa rotor imasanduka buluu, ndipo pazovuta kwambiri, kutuluka kwa aluminiyamu kumachitika.

Chachitatu, kwa ma rotor ambiri opangidwa ndi aluminiyamu, malekezero ake amakhala okhazikika. Komabe, ngati mapangidwewo ndi osamveka, kapena pali zochitika monga kuchulukira kwakukulu kwamakono ndi kukwera kwa kutentha kwapamwamba, malekezero a rotor angakhalenso ndi mavuto ofanana ndi ozungulira ozungulira, ndiko kuti, masamba a mphepo pamapeto pake amapunduka kwambiri. Vutoli ndilofala kwambiri m'magalimoto awiri, ndipo ndithudi limagwirizana mwachindunji ndi njira yopangira aluminium. Vuto lina lalikulu ndi loti aluminiyamu imasungunuka mwachindunji, zina zomwe zimachitika muzitsulo zozungulira, ndipo zina zomwe zimachitika pamphepete mwa rotor. Kunena zowona, vutoli likachitika, liyenera kuwunikiridwa kuchokera pamapangidwe ake, ndiyeno njira yopangira aluminiyamu iyenera kuwunikiridwa mozama.

Poyerekeza ndi gawo la stator, chifukwa cha mawonekedwe apadera a rotor yomwe ikuyenda, iyenera kuyesedwa mosiyana ndi milingo yamakina ndi magetsi, ndipo kutsimikizika kofunikira kuyenera kuchitidwa.
