Ma motor hub wamba ndi DC brushless mota, ndipo njira yowongolera ndiyofanana ndi ya servo motor.Koma mawonekedwe a motor hub motor ndi servo motor sizofanana ndendende, zomwe zimapangitsa kuti njira wamba yosankha servo motor isagwire ntchito mokwanira pagalimoto yamagalimoto.Tsopano, tiyeni tiwone momwe tingasankhire injini yoyenera ya hub.
Galimoto ya hub imatchulidwa molingana ndi kapangidwe kake, ndipo nthawi zambiri imatchedwa rotor DC brushless motor.Kusiyana kwa injini ya servo ndikuti malo ozungulira a rotor ndi stator ndi osiyana.Monga dzina limatanthawuzira, rotor ya hub motor ili pamphepete mwa stator.Chifukwa chake poyerekeza ndi mota ya servo, mota ya hub imatha kupanga torque yochulukirapo, zomwe zimatsimikizira kuti mawonekedwe amotowo ayenera kukhala othamanga kwambiri komanso othamanga kwambiri, monga mafakitale otentha a robotic.
Popanga dongosolo la servo, mutasankha mtundu wa servo system, m'pofunika kusankha actuator.Kwa dongosolo lamagetsi lamagetsi, ndikofunikira kudziwa mtundu wa injini ya servo molingana ndi katundu wa servo system.Ili ndiye vuto lofananira pakati pa servo mota ndi katundu wamakina, ndiye kuti, njira yamagetsi yamagetsi a servo system.Kufananiza kwa servo mota ndi katundu wamakina makamaka kumatanthawuza kufanana kwa inertia, mphamvu ndi liwiro.Komabe, posankha ma servo hubs, tanthauzo la mphamvu limafooka.Zizindikiro zofunika kwambiri ndi torque ndi liwiro, katundu wosiyanasiyana komanso kugwiritsa ntchito mosiyanasiyana kwa injini ya servo hub.Momwe mungasankhire torque ndi liwiro?
1.Kulemera kwa injini ya hub
Nthawi zambiri, maloboti ogwira ntchito adzasankhidwa ndi kulemera.Kulemera apa kumatanthawuza kulemera kwathunthu kwa robot ya utumiki (robot self-weight + load weight).Kawirikawiri, tiyenera kuonetsetsa kulemera kwathunthu tisanasankhe.Kulemera kwa injini kumatsimikiziridwa, makamaka magawo wamba monga torque amatsimikiziridwa.Chifukwa kulemera kumachepetsa kulemera kwa maginito amkati, omwe amakhudza torque ya injini.
2.Overload kuthekera
Kukwera kokwera komanso kuthekera kokwera pamwamba pa zopinga ndi chizindikiro chofunikira pakusankha ma robot a ntchito.Pamene kukwera, padzakhala chigawo chokoka (Gcosθ) chomwe chimapangitsa kuti robot yautumiki iwononge ntchitoyo, ndipo imayenera kutulutsa torque yaikulu;momwemonso, mbali yopendekera idzapangidwanso pokwera phiri.Iyeneranso kuthana ndi mphamvu yokoka kuti igwire ntchito, kotero kuti kuthekera kochulukira (ndiko kuti, torque yayikulu) kumakhudza kwambiri kuthekera kokwera phirilo.
3.Chiyembekezo cha liwiro
Kufunika kotsindika gawo la liwiro lovotera apa ndikuti ndikosiyana ndi mawonekedwe ogwiritsira ntchito ma mota wamba.Mwachitsanzo, makina a servo nthawi zambiri amagwiritsa ntchito mota + chochepetsera kuti apeze torque yayikulu.Komabe, makokedwe a motor hub palokha ndi yayikulu, kotero kugwiritsa ntchito torque yofananira ikapitilira liwiro lake kumapangitsa kutayika kwakukulu, zomwe zimapangitsa kutenthedwa kapena kuwonongeka kwa mota, chifukwa chake ndikofunikira kulabadira liwiro lake.Nthawi zambiri amalamulidwa mkati mwa nthawi 1.5 kuti athe kupeza zotsatira zabwino.
Chiyambireni kukhazikitsidwa kwake, Shenzhen Zhongling Technology Co., Ltd yakhala ikuyang'ana kwambiri pa R&D, kupanga ndi kukhathamiritsa kwa ma hub motors, kupatsa makasitomala zinthu zoyambira ndi mayankho omwe ali ndi malingaliro, luso, makhalidwe abwino komanso pragmatism.
