Spur geared DC motors
Li-motor tsa DC tse etselitsoeng lipolanete
Li-gearmotor tsena tse nyane li thata ka mokhoa o makatsang 'me li na le likere tsa tšepe tse felletseng. Li na le karo-karolelano ea lisebelisoa tsa 50: 1 ((karo-karolelano e 'ngoe ea 5, 10, 20, 30, 50,100,150,210,250,298,380,500,1000) 'me e sebetsa ho fihla ho 12 volts/24 volts mme e na le torque ea maz-in ea 20 a o. 5 ~ 2000RPM papali e 'ngoe le e' ngoe ea li-gearmotor tse 3mm D-shaft.
Gearmotor ena e na le enjene e nang le matla a tlase, 12 V brushed DC e kopantsoeng le 14: 1 enjene ea lipolanete tsa polanete, 'me e na le encoder e kopaneng ea 12PPR quadrature shaft, e fanang ka li-pulse tse 12 ka phetolo e ngoe le e ngoe ea mochini o hlahisoang ke lebokose la gear. Gearmotor e na le cylindrical, e bophara ba 36 mm feela, 'me shaft e nang le sebopeho sa D e bophara ba 8 mm mme e atoloha 20 mm ho tloha poleiti ea sefahleho ea lebokose la gear.
Ho sebelisoa likanale tse peli tsa Hall effect encoder ho utloa ho potoloha ha magnetic disk karolong e ka morao ea shaft ea enjene. Encoder ea quadrature e fana ka qeto ea lipalo tse 48 ka phetolo e ngoe le e ngoe ea shaft ea enjene ha ho baloa mahlakore ka bobeli a likanale ka bobeli. Ho bala lipalo ka phetoho e 'ngoe le e 'ngoe ea tlhahiso ea lebokose la gear, atisa tekanyo ea gear ka 14. Enjene/encoder e na le mebala e tšeletseng e nang le mebala, 8" (20 cm) e felisitsoeng ke hlooho ea 1 × 6 ea basali e nang le molumo oa 0.1 ″.
Sensor ea Hall e hloka motlakase o kenang, Vcc, pakeng tsa 3.5 le 20 V mme e hula boholo ba 10 mA. Liphetho tsa A le B ke maqhubu a lisekoere ho tloha ho 0 V ho ea ho Vcc hoo e ka bang 90° ho tsoa mokhahlelong. Khafetsa ea liphetoho e u bolella lebelo la motlakase, 'me taelo ea liphetoho e u bolella tsela.
Hlokomela:Li-torque tse thathamisitsoeng tsa li-stall le maqhubu ke litlhaloso tsa theory; li-unit li tla ema hantle pele ho lintlha tsena ha li-motor li ntse li futhumala. Ho ema kapa ho kenya li-gearmotor tse ngata haholo ho ka fokotsa nako ea bophelo ba tsona haholo mme ho baka tšenyo hanghang. Moedi o ka hodimo o kgothaletswang bakeng sa mejaro e tswelang pele ke 4 kg⋅cm (55 oz⋅in), mme moedi o ka hodimo o kgothaletswang bakeng sa torque e dumelletsweng nako le nako ke 8 kg⋅cm (110 oz⋅in). Li-stall li ka boela tsa baka ka potlako (mohlomong ka tatellano ea metsotsoana) tšenyo ea mocheso ho li-motor windings le borashe; tlhahiso e akaretsang bakeng sa ts'ebetso ea brushed DC motor ke 25% kapa ka tlase ho sebaka sa ho tsitsa.
