I-Spur geared DC motors
Ama-DC motors ahloselwe iplanethi
Lawa ma-micro gearmotor aqine ngendlela emangalisayo futhi afaka amagiya ensimbi agcwele. Anesilinganiso segiya esingu-50 :1 ((esinye isilinganiso esingu-5, 10, 20, 30, 50,100,150,210,250,298,380,500,1000) futhi asebenza aze afike ku-12 volts/24 volts futhi ane-torque engu-20 maz-in ye-maz-in engu-20 o. 5 ~ 2000RPM. I-micro gearmotor ngayinye idlala i-3mm D-shaft.
Le gearmotor iqukethe injini yamandla aphansi, engu-12 V exutshwe ne-DC motor ehlanganiswe ne-14: 1 planetary gear motor, futhi inomshini ohlanganisiwe we-12PPR quadrature encoder ku-motor shaft, ohlinzeka ngama-pulses angu-12 ngokuphenduka ngakunye kwe-shaft ephumayo ye-gearbox. I-gearmotor ingu-cylindrical, inobubanzi obungu-36 mm nje, kanti i-shaft ephumayo emise okwe-D ingu-8 mm ububanzi futhi inweba ngo-20 mm ukusuka ku-face plate ku-gearbox.
Isishumeki somphumela weHholo esineziteshi ezimbili sisetshenziselwa ukuzwa ukujikeleza kwediski kazibuthe endaweni engemuva yeshafu yemoto. Isifaki khodi se-quadrature sinikeza ukulungiswa kwezibalo ezingu-48 ngokuphenduka ngakunye kwe-motor shaft uma kubalwa womabili amaphethelo awo womabili amashaneli. Ukuze ubale izibalo ngokuphenduka ngakunye kokuphumayo kwebhokisi lika-gearbox, phindaphinda isilinganiso segiya ngo-14. Injini/isifaki khodi sinamakhodi ayisithupha anemibala, 8″ (20 cm) anqanyulwe unhlokweni wesifazane ongu-1×6 onephimbo elingu-0.1″.
Inzwa yeHholo idinga i-voltage yokufaka, i-Vcc, phakathi kuka-3.5 no-20 V futhi idonsa umkhawulo ongu-10 mA. Okuphumayo kuka-A no-B amagagasi ayisikwele ukusuka ku-0 V kuya ku-Vcc cishe ku-90° ngaphandle kwesigaba. Imvamisa yoshintsho ikutshela ijubane lemoto, futhi ukuhleleka koshintsho kukutshela isiqondiso.
Qaphela:Ama-torque kanye nama-currents e-stall asohlwini yi-extrapol of theory; amayunithi ngokuvamile azoma kahle ngaphambi kwalawa maphuzu njengoba izinjini zishisa. Ukuma noma ukulayisha ngokweqile ama-gearmotor kunganciphisa kakhulu impilo yawo futhi kubangele nomonakalo osheshayo. Umkhawulo ongaphezulu onconyiwe wemithwalo esetshenziswa ngokuqhubekayo ngu-4 kg⋅cm (55 oz⋅in), futhi umkhawulo ophezulu onconyiwe wetorque evunyelwe ngezikhathi ezithile ngu-8 kg⋅cm (110 oz⋅in). Izitebele nazo zingaholela ekulimaleni okusheshayo (okungenzeka ngokulandelana kwemizuzwana) kuma-motor windings namabhulashi; isincomo esijwayelekile sokusebenza kwe-brushed DC motor singama-25% noma ngaphansi kwamandla akhona.
