Katswiri wa Magalimoto Opanda Core Afotokoza Kusiyana Kofunika Pakati pa Torque Yotsekedwa ndi Torque Yoyambira mu Buku Latsopano la Ukadaulo

Bukuli likuyamba ndi funso lomwe mainjiniya opanga mapangidwe amafunsa kawirikawiri: Popeza torque yonse yotsekedwa ndi torque yoyambira imachitika pa liwiro la zero, kodi ndi gawo lomwelo? Malinga ndi muyezo wa IEC 60050-114 (wogwirizana ndi GB/T 2900.25), matanthauzidwewo akuwonetsa kusiyana kofunikira komwe kumakhudza mwachindunji mawerengedwe a magwiridwe antchito a mota.

Torque yozungulira yotsekedwa imatanthauzidwa kuti "torque yocheperako yoyezedwa yomwe imapangidwa pamene injiniyo imapatsidwa mphamvu pafupipafupi komanso mphamvu yamagetsi pomwe rotor yotsekedwa m'malo onse a angular." Mosiyana ndi zimenezi, torque yoyambira ndi "torque yamagetsi yopanda kukangana ndi mphamvu ya windage panthawi yoyambira kuyambira pa zero speed mpaka liwiro la katundu."

Mfundo vs. Ndondomeko: Kusiyana Kofunikira

Chosiyanitsa chapakati chili mu chikhalidwe chawo chachikulu. Torque yozungulira yotsekedwa imayimira mfundo imodzi yeniyeni ya data—mtengo wotsika wotsimikizika pazochitika zoyipa kwambiri. Kufotokozera kosamala kumeneku kumafotokoza kusinthasintha kwa torque komwe kumachitika chifukwa cha ma harmonics, kapangidwe ka slot, ndi geometry ya rotor magnetic circuit, makamaka kofunikira kwambiri mu ma motors asynchronous a single-phase komwe minda yozungulira yosazungulira ingapangitse kuti torque igwire bwino ntchito.

Komabe, mphamvu yoyambira imafotokoza njira yonse, osati mtengo umodzi. Imapereka curve yopitilira ya mphamvu yozungulira pakapita nthawi komanso liwiro. Ngakhale mphamvu yozungulira pa zero RPM ingafikire mtengo wotsekedwa wa injini zopangidwa bwino komwe kutayika kwa friction sikungatheke, dongosolo lamalingaliro limakhalabe losiyana.

Zotsatira Zothandiza pa Ntchito Zopanda Magalimoto

Kwa ogwiritsa ntchito injini zopanda coreless, kusiyana kumeneku sikungokhala kwamaphunziro chabe. Kufotokozera kwa torque yotsekedwa ngati mtengo wocheperako woyezedwa kumagwira ntchito ngati chitetezo chodalirika—kumatsimikizira kuti ngakhale pakakhala kusintha kwakukulu kwa torque, mphamvu yotsika kwambiri ya injiniyo idzapitirirabe zofunikira pakugwiritsa ntchito, ndikutsimikizira kuti imayamba bwino nthawi iliyonse.

"Ichi ndichifukwa chake ma datasheet athu a injini opanda core amatchula torque yotsekedwa ndi margins osasinthika," adatero Dr. Wang, Chief Technology Officer ku Sinbad Motor. "Mukugwiritsa ntchito zida zamankhwala komwe kuyambitsa kosagwira ntchito si njira yabwino, kumvetsetsa kuti gawoli likuyimira chocheperako chovomerezeka - osati mtengo wamba kapena wamba - kumalola mainjiniya kupanga ndi chidaliro."

Bukuli likumaliza kuti ngakhale kuti machitidwe akale amakampani nthawi zambiri amagwiritsa ntchito mawuwa mosinthana, uinjiniya wolondola umafuna kulunjika. Opanga ayenera kunena za "torque yoyambira pa liwiro la zero" kapena "torque yoyambira yocheperako" (malo otsika kwambiri a curve, omwe sangachitike pa liwiro la zero) kuti azitha kulankhulana momveka bwino.

About Sinbad Motor

Sinbad Motor ndi kampani yopanga ma mota a DC opanda mphamvu kwambiri, yomwe imapereka mayankho a injini zapadera pa ntchito zachipatala, zamlengalenga, zama robotiki, ndi zamafakitale. Ndi luso lapamwamba lopanga komanso njira zoyesera zotsatizana ndi IEC, kampaniyo imapereka ma mota omwe amakwaniritsa zofunikira kwambiri za torque ndi kudalirika.
