Cholinga ndi njira yokwaniritsira kutengera slot ya injini

Magawo atatu asynchronous motor rotor pachimake amatsekeredwa kuti atseke chozungulira chozungulira kapena aluminiyamu (kapena aluminiyamu yotayira, yamkuwa); stator nthawi zambiri slotted, ndipo ntchito yake ndinso phatikiza mafunde a stator.Nthawi zambiri, chute ya rotor imagwiritsidwa ntchito, chifukwa ntchito yoyikapo idzakhala yovuta kwambiri pambuyo pa stator ili ndi chute.Kodi cholinga chogwiritsa ntchito chute ndi chiyani?

Pali ma harmonic a ma frequency osiyanasiyana mkati mwa mota. Chifukwa stator utenga anagawira lalifupi mapiringidzo, ndi matalikidwe a harmonic maginito kuthekera mafupipafupi ena kupatula dzino harmonics ndi wofooka kwambiri.Popeza dzino lopiringitsa mafunde ndi lofanana ndi mafunde opindika, mphamvu ya maginito ya dzino simakhudzidwa.Chifukwa stator ndi rotor ya motor-phase asynchronous motor imapindika, kukana kwa maginito kwa gawo lonse la mpweya sikofanana, ndipo torque yamagetsi ndi mphamvu ya electromotive imasinthasintha molingana ndi injiniyo ikamayenda.

Pambuyo pa rotoryo, mphamvu yamagetsi yotchedwa electromagnetic torque yomwe imapangidwa ndi mphamvu yamagetsi yamagetsi imakhala yofanana ndi mtengo wamtengo wapatali womwewo wozungulira wozungulira womwe umagawidwa mozungulira, womwe ungathe kufooketsa mphamvu ya harmonic electromotive yomwe imapangidwa ndi mphamvu ya maginito ya mano, potero. kufooketsa ma torque awa owonjezera chifukwa cha maginito a harmonic amachepetsa kugwedezeka kwamagetsi ndi phokoso.Ngakhale kagawo kozungulira kozungulira kagawo kakang'ono kamachepetsanso mphamvu yamagetsi yamagetsi yoyendetsedwa ndi rotor, digiri ya skew slot yomwe nthawi zambiri imasankhidwa ndi yaying'ono kwambiri kuposa phula, motero ilibe mphamvu pang'ono pamachitidwe oyambira. Choncho, ang'onoang'ono ndi apakatikati kuponyedwa aluminium rotor asynchronous motors Rotor chutes amagwiritsidwa ntchito.

Zolemba za rotor zimakhomeredwa ndi njira yanthawi zonse, ndipo pakatikati pa rotor imakutidwa ndi dummy shaft yokhala ndi kiyi ya oblique. The oblique groove wa rotor pachimake ndi helical.

Ndiye kuti, zosoweka za rotor zimakhomeredwa ndi njira yanthawi zonse, ndipo pakatikati pa rotor imakutidwa ndi shaft yonyenga yokhala ndi helical oblique slot.Mphepete mwa nsonga ya rotor core ndi helical.

Ndiko kunena kuti, makina othamanga kwambiri amakhala ndi chowonjezera cha nkhonya, kotero kuti rotor iliyonse yokhomerera imawombera pepala limodzi, ndipo nkhonya yakufa imasuntha mtunda waung'ono pamodzi ndi njira yokhomerera. otsetsereka.Zolemba za rotor zomwe zakhomeredwa motere zitha kukhala zokonzeka kukhala ndi tsinde la rotor lomwe lili ndi shaft ya dummy yokhala ndi kiyi yowongoka.Mtundu woterewu wokhotakhota wa rotor pachimake ndiwopindulitsa makamaka kwa rotor yamkuwa, chifukwa chozungulira chozungulira chachitsulo sichikhala cha helical, koma chowongoka, chomwe ndi choyenera kuyika mipiringidzo yamkuwa.Komabe, dongosolo ndi malangizo a mapepala okhomerera omwe amakhomeredwa motere sangathe kusinthidwa, mwinamwake chitsulo chachitsulo chopangidwa ndi laminated sichingagwirizane ndi chitsanzocho.

Palibe opanga ambiri okhala ndi makina okhomerera othamanga kwambiri okhala ndi zida zokhomerera komanso zokhomera, ndipo ndizovuta kupanga makiyi ozungulira. Opanga ambiri amagwiritsa ntchito makiyi athyathyathya kuyika ma groove rotor cores.Rotor slot bar singagwiritsidwe ntchito pamene core rotor yasankhidwa ndi kiyi yowongoka ya oblique.Chifukwa poyambira mawonekedwe ndi ozungulira pa nthawi ino, ndigroove bar ndi yowongoka, ndizosatheka kugwiritsa ntchito groove bar yowongoka kukonza mawonekedwe ozungulira.Ngati mipiringidzo yolowetsedwa iyenera kugwiritsidwa ntchito, miyeso ya mipiringidzo yolowera iyenera kukhala yaying'ono kwambiri kuposa mipata yozungulira.Itha kugwira ntchito ngati ndodo yolowera.Chifukwa chake, posankha pachimake cha rotor ndi fungulo la oblique, fungulo la oblique limagwira ntchito ya skew ndi kuyika.Vuto lomwe mumakumana nalo mukamagwiritsa ntchito fungulo la oblique kuti musankhe pakati pa oblique groove rotor core ndi kusokoneza pakati pa helical skew ya keyway yokhomeredwa ndi skew yowongoka ya kiyi ya oblique.Ndiko kuti, kunja kwapakati pa rotor pachimake, payenera kukhala kusokoneza pakati pa nkhonya keyway ndi oblique key.
