Spur geared DC motors
Planetary geared DC motors
Cov micro gearmotors no yog qhov nyuaj heev thiab muaj cov iav hlau tag nrho. Lawv muaj qhov sib piv ntawm 50 : 1 ((lwm tus piv 5, 10, 20, 30, 50, 100, 150, 210, 250, 298, 380, 500, 1000) thiab ua haujlwm txog li 12 volts / 24 volts thiab muaj lub zog loj ntawm . 5 ~ 2000RPM Txhua micro gearmotor kis las 3mm D-ncej.
Lub gearmotor no muaj lub zog qis, 12 V brushed DC lub cev muaj zog ua ke nrog 14: 1 planetary iav lub cev muaj zog, thiab nws muaj kev sib xyaw 12PPR quadrature encoder ntawm lub cev muaj zog, uas muab 12 pulses ib kiv puag ncig ntawm lub gearbox cov zis ncej. Lub gearmotor yog cylindrical, nrog ib txoj kab uas hla tsuas yog 36 hli, thiab D-shaped tso zis ncej yog 8 hli nyob rau hauv txoj kab uas hla thiab ncua 20 hli ntawm lub ntsej muag phaj ntawm lub gearbox.
Ob-channel Hall effect encoder yog siv los txiav txim siab qhov kev sib hloov ntawm cov hlau nplaum disk ntawm lub nraub qaum ntawm lub cev muaj zog. Lub quadrature encoder muab qhov kev daws teeb meem ntawm 48 suav rau ib lub kiv puag ncig ntawm lub cev muaj zog thaum suav cov npoo ntawm ob qho tib si. Los xam cov suav ib lub kiv puag ncig ntawm cov zis gearbox, muab cov iav piv los ntawm 14. Lub cev muaj zog / encoder muaj rau xim-coded, 8 "(20 cm) ua tiav los ntawm 1 × 6 poj niam header nrog 0.1 "pitch.
Lub Hall sensor yuav tsum muaj qhov input voltage, Vcc, nruab nrab ntawm 3.5 thiab 20 V thiab kos qhov siab tshaj plaws ntawm 10 mA. A thiab B outputs yog square waves ntawm 0 V rau Vcc kwv yees li 90 ° tawm ntawm theem. Qhov zaus ntawm qhov kev hloov pauv qhia koj qhov ceev ntawm lub cev muaj zog, thiab qhov kev txiav txim ntawm qhov kev hloov pauv qhia koj cov kev taw qhia.
Nco tseg:Cov torques thiab cov tam sim no tau teev tseg yog qhov theoretical extrapolations; units feem ntau yuav nyob twj ywm zoo ua ntej cov ntsiab lus no thaum lub motors kub. Stalling lossis overloading gearmotors tuaj yeem txo lawv lub neej thiab ua rau muaj kev puas tsuaj tam sim ntawd. Qhov kev txwv siab tshaj plaws rau kev ua haujlwm tsis tu ncua yog 4 kg⋅cm (55 oz⋅in), thiab qhov kev pom zoo sab saud rau kev tso cai torque yog 8 kg⋅cm (110 oz⋅in). Cov khw muag khoom kuj tuaj yeem ua rau sai (tej zaum ntawm qhov kev txiav txim ntawm lub vib nas this) thermal puas rau lub cev muaj zog windings thiab txhuam; Kev pom zoo dav dav rau kev ua haujlwm ntawm DC lub cev muaj zog yog 25% lossis tsawg dua ntawm cov khoom siv tam sim no.
