Zvinotendwa kuti mota ndiyo yega chinhu chikuru muhurongwa hwekudzora kufamba. Zvisinei, mumakore angu ekushanda ne miniature drive systems, ndasvika pakuona kuti njere dzechokwadi - kugona kuwana nekuchengetedza kutonga kwakarurama - dziri mu encoder chete. Kana usina iyi critical feedback loop, mota yacho yakaita seyenzou. Izvi zvakakosha zvikuru kunemota dzemagiya madikinekuti kutsungirira kwavo zvikanganiso kwakaderera zvikuru. Sarudza encoder yakakodzera haisi dambudziko rehunyanzvi chete, asi muganho wekuvimbika kwechigadzirwa chose uye kushanda kwesarudzo huru.

Nei maEncoders ari "pfungwa" dzemaDC Gear Motors madiki

Kubatanidzwa kwe encoder nemota diki yeDC giyaZvakafanana nekushandura simba remagetsi kuita sisitimu yakaoma yekudzora yakavharwa. Iyo encoder yekupa data rinodiwa, senge nzvimbo, kumhanya uye gwara inoita kuti controller igone kugadzirisa panguva chaiyo. Izvi zvakakosha kune mashandisirwo anoda kunyatsojeka. Semuenzaniso, funga nezvemuchina wekurapa unotakurika - mota yegiya diki inoshandiswa pakurapa - nzvimbo chaiyo yekutakura mvura kana nezvekuchengetedzwa kwemurwere. Iyo encoder inovimbisa kuti kubuda kwemota, kunyangwe mushure mekuderedzwa kwegiya, kunoenderana zvizere nezvinodiwa zvesisitimu.

Dambudziko rekugadzirisa: Zvakawanda hazvisi nani nguva dzose

Mainjiniya vanowanzo kanganisa nekufunga kuti mhinduro yepamusoro-soro (pulses per revolution, PPR) ndiyo sarudzo yakanakisisa nguva dzose. Kunyangwe chiri chokwadi kuti mhinduro yepamusoro inopa kutonga kwakanaka, asi inowedzerawo kuomarara uye mutengo.

• Mutengo chaiwo wePPRS yakakwira:

Kugadziriswa kwepamusoro kunoreva kuti controller inoda kugadziriswa kwemasaini nekukurumidza. Kunonoka uye zvikanganiso zvinogona kuiswa kana microcontroller isingakwanise kuenderana ne pulse frequency. Pamusoro pezvo, kugadziriswa kwe output shaft kwakagadziridzwa zvakanyanya kune high gear ratio 12V micro gear motors. Tinofanira kuzvibvunza kuti: mutengo wekuwedzera uye kuomarara kwe1024 PPR encoders kunokosha here kana 256 PPR encoder ichikwanisa kusangana nezvinodiwa chaizvo zvekushandisa?

• Mazano anoshanda:

Kurudziro yangu ndeyekuti utange waverenga kururama kwenzvimbo inodiwa pakubvisa shaft yekupedzisira wobva wadzokera kumashure. Kune akawanda mashandisirwo evatengi, uye kunyangwe akawanda mashandisirwo emaindasitiri, resolution iri pakati nepakati uye yakagadzikana inowanzova sarudzo yekuchenjera uye isingadhuri.

Ma encoders ekuona uye emagineti: Zvinhu zvezvakatipoteredza

Kusarudzwa kwe optical kana magnetic encoder kunoenderana zvakanyanya nemamiriro ekushanda kwemota pane mashandiro ayo.

• Kunzwa kweOptical: MaOptical encoders akarurama zvikuru uye anoshandisa chiedza kuverenga dhisiki rekodhi. Zvisinei, anonyanya kunzwa guruva, hunyoro uye kuchinja-chinja kwekupisa kwakanyanya. Kana application yako iri munzvimbo yakaoma - senge muchina wekutengesa kana sensor yekunze - inogona kukonzera kukundikana nekukurumidza. Kugadzikana kwemagnetic encoder: verenga magnetic disk, magnetic encoder inoshandisa hall effect sensors "inonyanya kukosha" muindasitiri. Zvekusvibisa uye kuramba vibration zviri nani kupfuura optical encoder. Kunyange zvazvo zvingave zvisina kunyatsojeka pane optical encoders, kuvimbika kwavo munzvimbo dzakaoma kunoita kuti vakwanise kushandiswa senge automation systems kana industrial automation.

Pfungwa yePincheng: kubatanidzwa uye kugadzirisa

• Kunze kwebhuku redata: Hatingotengesi zvinhu chete, asi tinovaka mhinduro. Kana mutengi akauya kuzobvunza nezvemota ye microgear yechigadzirwa chitsva, tinoongorora sisitimu yese - kusanganisira mutoro, duty cycle uye mamiriro ekunze - tisati takurudzira encoder yakakodzera. Izvi zvinoita kuti kubatana kwemechanical coupling kusakanganiswa, electrical interface ive yakajeka uye yakarurama, system yekupedzisira inogona kushanda zvakakwana sezvaitarisirwa.

• Zvakanakira kugadzirisa: Pazvinodiwa zvakakosha, zvakaita semota dzema microgear dzekurapa dzinoda PPR isiri yemhando yepamusoro kana masaini emagetsi akasiyana, tinokwanisa kugadzirisa interface ye encoder zvakananga mufekitori, zvichiponesa vatengi nguva yakawanda uye zvichideredza njodzi yekukanganisa kwekubatanidza. Izvi zvakakosha zvikuru kune michina inoda kushanda kwenguva refu yakavimbika pasina kugadziriswa.

Pakupedzisira, kuti usarudze zvakakodzeramota yegiya yeDCencoder chisarudzo chehurongwa, chinodiwa kuti pave nekuenzana pakati pezvinodiwa zvehunyanzvi nezvinodiwa chaizvo zvekushandisa.

Unofanira kusarudza izvi nemumwe wako anonzwisisa hunhu hwesimba rekufamba kwemuchina. Nekutarisa pane zvinodiwa chaizvo zvechishandiso chako, kwete chete nhamba yepamusoro mupepa redata, unogona kuve nechokwadi chekuti chigadzirwa chinogara kwenguva refu uye chakarurama. Sarudza vadyidzani vanogona kupa mhinduro dzakabatana uye dzakavimbika.
