Spur geared DC motors
Ma motors a DC opangidwa ndi mapulaneti
Ma micro gearmotor awa ndi olimba kwambiri ndipo amakhala ndi zida zonse zachitsulo. Iwo ali ndi magiya chiŵerengero cha 50 :1 ((chiŵerengero china 5, 10, 20, 30, 50,100,150,210,250,298,380,500,1000) ndipo amagwira ntchito mpaka 12 volts/24 volts ndipo ali ndi torque ya 20 mazx ndi ma ox 20. 5 ~ 2000RPM Iliyonse yamagetsi yamagetsi ya 3mm D-shaft.
Gearmotor iyi imakhala ndi mphamvu yotsika, 12 V yopukutira DC mota yophatikizika ndi 14: 1 pulaneti yamagetsi, ndipo ili ndi encoder yophatikizika ya 12PPR quadrature pa shaft yamagalimoto, yomwe imapereka ma pulses 12 pakusinthika kwa shaft ya gearbox. Gearmotor ndi cylindrical, yokhala ndi mainchesi 36 mm, ndipo shaft yopangidwa ndi D ndi 8 mm m'mimba mwake ndikupitilira 20 mm kuchokera pa mbale yakumaso ya gearbox.
Encoder ya Hall effect imagwiritsa ntchito njira ziwiri kuti izindikire kuzungulira kwa maginito disk kumbuyo kwa shaft ya motor. Encoder ya quadrature imapereka kusintha kwa ma 48 pakusintha kwa shaft yamoto powerengera mbali zonse ziwiri za tchanelo. Kuti muwerenge ziwerengero pakusintha kwa gearbox, chulukitsani chiŵerengero cha giya ndi 14. Motor/encoder ili ndi zotsogola zisanu ndi imodzi, 8" (20 cm) zomwe zimathetsedwa ndi mutu wachikazi wa 1 × 6 wokhala ndi phula la 0.1 ″.
Sensa ya Hall imafuna magetsi olowera, Vcc, pakati pa 3.5 ndi 20 V ndipo imakoka kwambiri 10 mA. Zotsatira za A ndi B ndi mafunde masikweya kuchokera ku 0 V mpaka Vcc pafupifupi 90 ° kunja kwa gawo. Mafupipafupi a masinthidwe amakuuzani liwiro la mota, ndipo dongosolo la masinthidwe limakuuzani momwe mungayendere.
Zindikirani:Ma torque omwe adalembedwa ndi mafunde ndi owonjezera; mayunitsi nthawi zambiri amayima patsogolo pa mfundozi pamene ma motor akuwotcha. Kuyimilira kapena kudzaza ma gearmotor kumatha kuchepetsa kwambiri moyo wawo komanso kuwononga nthawi yomweyo. Malire apamwamba ovomerezeka a katundu omwe akugwiritsidwa ntchito mosalekeza ndi 4 kg⋅cm (55 oz⋅in), ndipo malire ovomerezeka a torque yovomerezeka nthawi ndi nthawi ndi 8 kg⋅cm (110 oz⋅in). Malo osungira amathanso kubweretsa mwachangu (mwina mwadongosolo la masekondi) kuwonongeka kwa matenthedwe a ma motor windings ndi maburashi; lingaliro wamba pa brushed DC motor ntchito ndi 25% kapena kuchepera pa khola panopa.
