Kusankha Njinga Yoyenera: Zoyambira za Torque, Kuthamanga, ndi Kukula

Pali mitundu yosiyanasiyana yamota wopanda mazikomdziko lapansi. Ma motors akuluakulu ndi ma motors ang'onoang'ono. Mtundu wa injini yomwe imatha kuyenda mmbuyo ndi mtsogolo popanda kuzungulira. Poyamba, sizikudziwika chifukwa chake ndi okwera mtengo kwambiri. Komabe, pali chifukwa chosankha mitundu yonse yamota wopanda maziko. Ndiye, ndi mitundu yanji ya ma mota, magwiridwe antchito, kapena mawonekedwe omwe amafunikira pagalimoto yabwino yamagetsi?

Cholinga cha mndandandawu ndikupereka chidziwitso cha momwe mungasankhire mota yabwino. Tikukhulupirira kuti zidzakuthandizani mukasankha injini. Tikukhulupirira kuti ikhoza kuthandiza anthu kudziwa zambiri zamainjini.

1. Torque

Torque ndi mphamvu yomwe imayambitsa kuzungulira.mota wopanda mazikoamapangidwa m'njira zosiyanasiyana kuti awonjezere torque. Kutembenuka kwa mawaya a electromagnetic kumapangitsa kuti torque ichuluke. Chifukwa cha kukula kwa ma coil okhazikika, waya wa enameled wokhala ndi mainchesi akulu amagwiritsidwa ntchito. Mitundu yathu yamagalimoto yopanda maburashi imaphatikizapo kukula kwake ndi 16mm, 20mm, 22mm, 24mm, 28mm, 36mm, 42mm, ndi 50mm. Pamene kukula kwa koyilo kumachulukiranso ndi mainchesi a motor, torque yapamwamba imatha kupezeka.

Maginito amphamvu amagwiritsidwa ntchito kupanga torque yayikulu popanda kusintha kukula kwa injini. Maginito osowa padziko lapansi ndi maginito amphamvu kwambiri okhazikika, otsatiridwa ndi maginito a magnesium cobalt. Komabe, ngakhale mutagwiritsa ntchito maginito amphamvu, maginito amatuluka mugalimoto, ndipo maginito otayira sangawonjezere torque. Kuti mugwiritse ntchito mokwanira maginito amphamvu, chinthu chochepa kwambiri chogwira ntchito chotchedwa electromagnetic steel plate chimapangidwa ndi laminated kuti chiwongolere maginito.

2. Liwiro (kusintha)

Liwiro la mota yamagetsi nthawi zambiri limatchedwa "liwiro". Ndi ntchito ya kangati injini imazungulira pa unit ya nthawi. Poyerekeza ndi torque, kuwonjezera kuchuluka kwa ma rotator sikovuta mwaukadaulo. Ingochepetsani kuchuluka kwa kutembenuka kwa koyilo kuti muwonjezere kuchuluka kwa kuzungulira. Komabe, popeza torque imacheperako pomwe kuchuluka kwa kasinthasintha kumawonjezeka, ndikofunikira kukwaniritsa zofunikira za torque ndi liwiro lozungulira.

Kuphatikiza apo, ngati agwiritsidwa ntchito mothamanga kwambiri, ndi bwino kugwiritsa ntchito mayendedwe a mpira m'malo mwa mayendedwe wamba. Liwiro likakwera kwambiri, kutayika kwamphamvu kwamagetsi kumakulirakulira, komanso kufupikitsa moyo wagalimoto. Malingana ndi kulondola kwa shaft, kuthamanga kwapamwamba, phokoso lalikulu ndi nkhani zokhudzana ndi kugwedezeka. Popeza maburashi opanda maburashi alibe maburashi kapena ma commutators, amatulutsa phokoso lochepa komanso kugwedezeka kuposa ma motors opukutidwa (omwe amalumikizana pakati pa maburashi ndi makina ozungulira).

3. Kukula

Polankhula za mota yabwino yamagetsi, kukula kwa injiniyo ndi chimodzi mwazinthu zofunika kwambiri pakuchita. Ngakhale liwiro (kuzungulira) ndi torque ndizokwanira, zilibe tanthauzo ngati sizingayikidwe muzomaliza.

Ngati mukufuna kungowonjezera liwiro, mutha kuchepetsa kuchuluka kwa waya. Ngakhale kuchuluka kwa kutembenuka kuli kochepa, sikungazungulira pokhapokha ngati pali torque yochepa. Chifukwa chake, ndikofunikira kupeza njira zowonjezera ma torque.

Kuphatikiza pa kugwiritsa ntchito maginito amphamvu omwe tawatchula pamwambapa, kukulitsa ntchito ya ma windings ndikofunikiranso. Takhala tikukambirana za kuchepetsa kuchuluka kwa ma windings kuti titsimikizire kuchuluka kwa matembenuzidwe, koma izi sizikutanthauza kuti waya wavulala momasuka.

M'malo kuchepetsa chiwerengero cha windings ndi mawaya wandiweyani kungathenso kukwaniritsa lalikulu panopa ndi mkulu makokedwe pa liwiro lomwelo. The space factor ndi chisonyezo cha momwe waya wavulala mwamphamvu. Kaya ndikuwonjezera kuchuluka kwa matembenuzidwe oonda kapena kuchepetsa kuchuluka kwa kutembenuka kokhuthala, ndikofunikira kwambiri kuti mupeze torque.
