Phunzirani pakutayika kwakukulu kwa silicon steel motor stator poganizira kutentha ndi kupsinjika kwapakatikati

Popeza pachimake chamoto nthawi zambiri chimakhudzidwa ndi zinthu zosiyanasiyana monga maginito, gawo la kutentha, malo opanikizika, komanso pafupipafupi pakugwira ntchito; nthawi yomweyo, zinthu zosiyanasiyana processing zinthu monga zotsalira kupsyinjika kwaiye ndi kuponda ndi kukameta ubweya wa pakachitsulo zitsulo mapepala, mtunda pakati pa chipolopolo ndi pachimake stator The compressive kupsyinjika kwaiye ndi manja kutentha, ndi centrifugal mavuto kwaiye ndi mkulu-liwiro ntchito. ya rotor, ndi kutentha kwa gradient komwe kumapangidwa ndi mawonekedwe a kukwera kwa kutentha kudzakhudza magwiridwe antchito onse pachimake. Zinthu izi zipangitsa kuti kutayika kwachitsulo kwapakati pamoto kukhala wapamwamba kuposa mtengo wamba ndikupangitsa kuwonongeka kosafunikira.

Zotsatira za kafukufuku kunyumba ndi kunja zikusonyeza kuti: pachimake chitsulo cha galimoto nthawi zambiri ntchito kutentha kwambiri, imfa ya chitsulo wamba pakachitsulo zitsulo pepala amachepetsa ndi kuwonjezeka kutentha, pamene chitsulo imfa ya 6.5% mkulu pakachitsulo zitsulo kumawonjezeka ndi kuwonjezeka kwa kutentha. Pakuti Motors anaika ndi kusokoneza koyenera mu mlanduwo, mlandu adzakhala ndi nkhawa kwambiri pachimake chitsulo, ndi galimoto chitsulo pachimake adzakhala ndi compressive maganizo a za 10Mpa-150Mpa pa ntchito, ndi chipika mtundu chitsulo pachimake ndi abwino kwambiri kupanga misa, yomwe nthawi zambiri A shrink fit kapena compression process imafunika kukonza pachimake, ndipo kutayika kwachitsulo kwa injini yokhala ndi shrink fit kapena press fit kumawonjezeka kwambiri poyerekeza ndi vuto losapanikizika. Zomwe zili mu 6.5% zitsulo zapamwamba za silicon ndizokwera kwambiri kuposa zitsulo zachikhalidwe za silicon, kotero kutayika kwachitsulo kwa 6.5% kutsika kwachitsulo cha silicon kumakhala kochepa chifukwa cha kuwonjezeka kwa kupsinjika maganizo, pamene kutayika kwachitsulo kwachitsulo chachitsulo kumakhala kokulirapo. kuonjezera kupsinjika maganizo. Kuwonongeka kwachitsulo chifukwa cha kupanikizika kwapang'onopang'ono kumakhala kochepa, ndipo pamene kupanikizika kumafika pamtengo wina, kuwonongeka kwa chitsulo sikukuwonekeranso.

Ma Deji, wofufuza pa Shenyang University of Technology, adayesa maginito a 6.5% high-silicon steel pansi pazikhalidwe za compressive stress and heat coupling, and review the iron loss model, and poyerekeza 6.5 % high-silicon steel with traditional silicon. zitsulo. Kuchokera pamalingaliro azinthu, ubwino wa 6.5% mkulu silicon zitsulo amawunikidwa. Ndipo bwererani ku core motor kuti ntchito yake ikhale yabwino kwambiri.

Kupyolera mu kafukufuku wokhudza kutayika kwachitsulo kwa 6.5% Si pansi pa kutentha kosiyana ndi kupsinjika maganizo, ofufuzawo adapeza kuti: pamene kutentha ndi kupsinjika maganizo komwe kumagwira ntchito kumawonjezeka, poyerekeza ndi zitsulo zina zachikhalidwe za silicon, kuwonongeka kwa 6.5% Si ndi ochepa kwambiri; Chitsulo cha 6.5% chapamwamba cha silicon chimakhala ndi kuwonongeka kwachitsulo chochepa pansi pamikhalidwe yambiri yolumikizana ndi mafiziki chifukwa cha kupsinjika kwamkati, kokwanira kakang'ono ka hysteresis ndi kukula kwakukulu kwambewu; pamene 6.5% high-silicon zitsulo zimagwiritsidwa ntchito popanga injini ya stator pachimake, casing imatenga shrink fit Ikayikidwa mofanana, padzakhala kutaya kwachitsulo pang'ono.
