Kusankha Mota Yoyenera: Zoyambira za Torque, Liwiro, ndi Kukula

Pali mitundu yosiyanasiyana yamota yopanda corelesspadziko lonse lapansi. Ma mota akuluakulu ndi ang'onoang'ono. Mtundu wa mota womwe ungayende mozungulira popanda kuzungulira. Poyamba, sizikudziwika chifukwa chake ndi okwera mtengo chonchi. Komabe, pali chifukwa chosankhira mitundu yonse yamota yopanda corelessNdiye, ndi mitundu iti ya injini, magwiridwe antchito, kapena makhalidwe omwe amafunikira kuti mota yamagetsi yoyenera ikhale yabwino?

Cholinga cha mndandanda uwu ndikupereka chidziwitso cha momwe mungasankhire injini yoyenera. Tikukhulupirira kuti idzakuthandizani mukasankha injini. Tikukhulupirira kuti ingathandize anthu kuphunzira chidziwitso choyambira cha injini.

1. Mphamvu

Mphamvu ya torque ndi mphamvu yomwe imayambitsa kuzungulira.mota yopanda corelessZapangidwa m'njira zosiyanasiyana kuti ziwonjezere mphamvu yamagetsi. Ma waya amagetsi akamazungulira kwambiri, mphamvu yamagetsi imakulanso. Chifukwa cha kukula kwa ma coil okhazikika, waya wopangidwa ndi enamel wokhala ndi mainchesi akulu amagwiritsidwa ntchito. Mndandanda wathu wamagalimoto opanda burashi umaphatikizapo kukula kwake ndi mainchesi akunja a 16mm, 20mm, 22mm, 24mm, 28mm, 36mm, 42mm, ndi 50mm. Pamene kukula kwa coil kumawonjezekanso ndi mainchesi a injini, mphamvu yamagetsi imakulanso.

Maginito amphamvu amagwiritsidwa ntchito popanga mphamvu yayikulu popanda kusintha kukula kwa injini. Maginito a rare earth ndi maginito amphamvu kwambiri okhazikika, kutsatiridwa ndi maginito a magnesium cobalt. Komabe, ngakhale mutagwiritsa ntchito maginito amphamvu okha, mphamvu ya maginito imatuluka mu injiniyo, ndipo mphamvu ya maginito yotuluka sidzawonjezera mphamvu ya maginito. Kuti mugwiritse ntchito mphamvu ya maginito mokwanira, chinthu chopyapyala chotchedwa electromagnetic steel plate chimayikidwa laminated kuti chiwongolere kayendedwe ka maginito.

2. Liwiro (kusintha)

Liwiro la mota yamagetsi nthawi zambiri limatchedwa "liwiro." Ndi momwe injini imazungulira kangati pa unit ya nthawi. Poyerekeza ndi torque, kuwonjezera kuchuluka kwa ma rotations sikovuta kwenikweni. Ingochepetsani kuchuluka kwa ma turn mu coil kuti muwonjezere kuchuluka kwa ma rotations. Komabe, popeza torque imachepa pamene kuchuluka kwa ma rotations kukukwera, ndikofunikira kukwaniritsa zofunikira pa torque komanso liwiro lozungulira.

Kuphatikiza apo, ngati ikugwiritsidwa ntchito pa liwiro lalikulu, ndi bwino kugwiritsa ntchito ma bearing a mpira m'malo mwa ma bearing wamba. Liwiro likakwera, kukana kukangana kumachepa kwambiri, komanso moyo wa injini umafupikitsidwa. Kutengera ndi kulondola kwa shaft, liwiro likakwera, mavuto okhudzana ndi phokoso ndi kugwedezeka amakula kwambiri. Popeza ma mota opanda maburashi alibe maburashi kapena ma commutator, amapanga phokoso ndi kugwedezeka kochepa kuposa ma mota opangidwa ndi ma brushed (omwe amalumikizana pakati pa maburashi ndi commutator yozungulira).

3. Kukula

Ponena za mota yamagetsi yoyenera, kukula kwa mota ndi chimodzi mwazinthu zofunika kwambiri pakugwira ntchito. Ngakhale liwiro (kuzungulira) ndi mphamvu zake zili zokwanira, sizili ndi tanthauzo ngati sizingakhazikitsidwe mu chinthu chomaliza.

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

Kuwonjezera pa kugwiritsa ntchito maginito amphamvu omwe atchulidwa pamwambapa, kuwonjezera mphamvu ya ma windings ndikofunikiranso. Takhala tikukambirana za kuchepetsa kuchuluka kwa ma windings kuti tiwonetsetse kuti ma turns ndi ochuluka, koma izi sizikutanthauza kuti waya wapindika mosasamala.

Kusintha mawaya okhuthala kuti achepetse kuchuluka kwa ma windings kungathandizenso kuti pakhale mphamvu yayikulu komanso mphamvu yayikulu pa liwiro lomwelo. Chizindikiro cha malo ndi chizindikiro cha momwe wayayo yagwiritsidwira ntchito mwamphamvu. Kaya ikuwonjezera kuchuluka kwa ma currents owonda kapena kuchepetsa kuchuluka kwa ma currents okhuthala, ndi chinthu chofunikira kwambiri kuti pakhale mphamvu.
