DSPOWER idayamba mu 2012, ikuyang'ana pa kafukufuku ndi chitukuko chopanga maphunziro a robot servo, servo yanzeru ya robot ndi Building Block servo.

Mukapanga maloboti kapena zida zanzeru, kulondola kwamakona kwa ma servo motors nthawi zambiri kumakhala chinthu chosaiwalika koma chofunikira kwambiri. Mwinamwake mwakumanapo ndi zochitika zomwe injini ya servo imalephera kuyendayenda kumalo omwe mukufuna, kapena malo omwe amafikira amasiyana pang'ono nthawi iliyonse, zomwe zimayambitsa kusakhazikika kwadongosolo lonse.

Izi ndichifukwa choti simunalabadire kulondola kwamphamvu kwa injini ya servo, ndipo mwangoyang'ana magawo oyambira monga torque ndi liwiro.

Kodi Servo Motor Angular Accuracy ndi chiyani?

Kulondola kwa ma angular a Servo motor kumatanthawuza kuchuluka kwapatuka pakati pa malo enieni ozungulira ndi malo omwe amatsata pambuyo polandira chizindikiro chowongolera. Mwachitsanzo, injini ya servo yokhala ndi ± 1 ° yolondola, yozungulira mpaka 90 °, ikhoza kukhala pakati pa 89 ° ndi 91 °. Mtengo wolondola uwu nthawi zambiri umaperekedwa ndi wopanga magalimoto a servo muukadaulo.

Ndi chimodzi mwazizindikiro zazikulu zoyezera magwiridwe antchito a servo motor. Ma seva olondola kwambiri amawonetsetsa kusuntha kolondola komanso kobwerezabwereza kwa zida zanu, makamaka pazochitika zomwe zimafuna kuwongolera bwino, monga kugwira mkono kwa robotiki ndi kuyika kwa kamera ya gimbal.

Kumvetsetsa kufunikira kwa kulondola kwa angular, komwe sikumapezeka nthawi zonse, kumakuthandizani kupeŵa mavuto ambiri omwe angakhalepo panthawi yofunikira ya polojekiti. Ma servos otsika mtengo koma otsika olondola amatha kuyambitsa zolakwika zambiri m'dongosolo lonse, zomwe zimakhudza magwiridwe ake onse ndikubweretsa zotsatira zoyipa.

Chifukwa chake, posankha servo, muyenera kuwunika mosamala magawo okhudzana ndi kulondola ndikuyika patsogolo zinthu zomwe zimafotokoza momveka bwino miyezo yawo yolondola, m'malo mopanga zisankho motengera zomwe zidachitika kale kapena mtengo.

Chifukwa Chake Kulondola kwa Angular Ndikofunikira Pama projekiti

Kulondola kwa angular kumatsimikizira mwachindunji kuchitidwa kodalirika kwa ntchito ndi zida. Mwachitsanzo,ngati mukugwira ntchito yolondolera yokha, kusalondola kwa servo kudzalepheretsa kamera kulunjika molondola chandamale, ndikuchepetsa kwambiri kutsatira.Momwemonso, mu makina opanga mafakitale, ma servo otsika amatha kuyambitsa kusokonekera kwa mkono wa robotic komanso zovuta kupanga.

Kusakhazikika kosakwanira sikumangokhudza magwiridwe antchito komanso kumawonjezera nthawi yokhazikitsira ndi mtengo wake chifukwa chakufunika kokonzanso mobwerezabwereza kapena kusintha magawo.

Kuchokera pamawonekedwe a ogwiritsa ntchito, ma servos olondola kwambiri amathandiza kuti chipangizocho chizigwira ntchito bwino komanso mwaukadaulo. Mwachitsanzo, m'maloboti ophunzirira kapena zoseweretsa zanzeru, mayendedwe olondola amathandizira kulumikizana ndikuletsa kukhumudwa kwa ogwiritsa ntchito chifukwa cha zida zosalabadira.

Chifukwa chake, ngakhale kuyika ndalama mu ma servos olondola kwambiri kungawoneke ngati kukulitsa ndalama zoyambira, kumapangitsa kuti chiwongola dzanja chichitike komanso kukhazikika kwanthawi yayitali, ndikupangitsa chisankho chotsika mtengo kwambiri.

Momwe Mungasankhire Ma Servo Apamwamba Olondola

Posankha servo yolondola kwambiri, choyambira ndikuwunika zomwe zagulitsidwa ndikuyang'ana manambala omveka bwino kuti akhale olondola mwamakona, monga ± 0.5 ° kapena ± 1 °. Nthawi zambiri, ma servos a digito ndi olondola kwambiri kuposa ma analogi chifukwa amagwiritsa ntchito ma microprocessors pakuwongolera kotseka, kulola kusintha kwanthawi yeniyeni.

Nthawi yomweyo, tcherani khutu ku mtundu wa servo; ma motors opanda ma brushless kapena ma coreless motors nthawi zambiri amakhala ndi maubwino olondola komanso moyo wautali, pomwe ma mota opanda coreless amapereka zabwino munthawi yayitali yogwira ntchito komanso kutentha kwabwinoko.

Ganizirani momwe mungagwiritsire ntchito.Ngati polojekiti yanu ikufuna kuyankha mwachangu komanso kulondola kwambiri, mutha kusankha servo ya digito yomwe imathandizira kutsitsimuka kwakukulu; ngati bajeti yanu ili yochepa koma zofunikira zolondola sizokwera, servo yokhazikika ikhoza kukhala yokwanira.

Kuphatikiza apo, werengani ndemanga za ogwiritsa ntchito ndi malipoti oyesa kuti mumvetsetse momwe ntchito ikugwiritsidwira ntchito kwenikweni, kupewa zisankho zongotengera zongoyerekeza. Kumbukirani, ma servos olondola kwambiri nthawi zambiri amafunikira ma voltage okwera komanso chithandizo chowongolera bwino, monga mabasi a TTL kapena mabasi a CAN.

Kodi Ndi Zinthu Ziti Zomwe Zimakhudza Kulondola kwa Servo?

Kulondola kwa mota ya servo kumakhudzidwa ndi zinthu zosiyanasiyana, kuphatikiza mawonekedwe amkati ndi chilengedwe chakunja. Zinthu zamkati makamaka zimaphatikizira kumbuyo kwa gear, mtundu wamagalimoto, ndi njira yoyankha. Ma servo okhala ndi zida zazikulu zakumbuyo amakumana ndi hysteresis panthawi yozungulira, zomwe zimapangitsa kuchepa kulondola.

Komabe, ma servos otsekeka okhala ndi ma encoder amagwiritsa ntchito njira zowunikira kuti achepetse zolakwika, potero amawongolera kulondola. Zinthu zakunja zikuphatikiza kukhazikika kwamagetsi amagetsi, mtundu wazizindikiro zowongolera, komanso kusiyanasiyana kwa katundu.

Mwachitsanzo, kusinthasintha kwamagetsi kumatha kuyambitsa kuthamanga kwa ma servo mosiyanasiyana, kusokoneza kulondola kwamalo. Phokoso mu chizindikiro chowongolera lingasokonezenso kutanthauzira kwa lamulo la servo. Kuphatikiza apo, katundu wambiri kapena kuyika kosayenera kungayambitsenso kutayika kolondola.

Chifukwa chake,mukamagwiritsa ntchito ma servos olondola kwambiri, ndikofunikira kuwonetsetsa kuti magetsi azikhala okhazikika, chizindikiro choyera, komanso makina opangidwa bwino kuti apititse patsogolo ntchito.

Momwe Mungayesere ndi Kuyesa Kulondola kwa Servo?

Mutha kugwiritsa ntchito zida zosavuta, mongaangle gauge kapena laser pointer, kutumiza zizindikiro zolondola kwa wowongolera kuti ayese kulondola kwa servo.Tembenuzani servo pamakona angapo omwe mukufuna, monga 0°, 90°, ndi 180°, kenako yesani malo enieni ndikuwerengera kupotokolako.

Bwerezani izi kangapo ndikutenga avareji kuti muwunikire kubwereza. Ngati kupatuka kuli kwakukulu, kuwongolera kungakhale kofunikira. Ma servos ambiri a digito amathandizira kuwongolera mapulogalamu, omwe amalipira zolakwika posintha magawo owongolera.

Kuwongolera kumaphatikizapo kutumiza malamulo owongolera kapena kugwiritsa ntchito mapulogalamu apadera. Mwachitsanzo, microcontroller ikhoza kutumiza chizindikiro cha PWM ndikulemba kusiyana pakati pa malo enieni ndi mtengo wamaganizo, kenaka yonjezerani kuchotsera pa code kuti mukonze.

Kuyesa pafupipafupi komanso kuwongolera kumatha kukulitsa moyo wa servo ndikuwonetsetsa kugwira ntchito kwanthawi yayitali. Pazovuta kwambiri, tikulimbikitsidwa kuti mutsirize masitepe awa musanayike kuti mupewe zovuta pakuwongolera pambuyo pake.

Kugwiritsa Ntchito Wamba kwa High Precision Servos

Ma servos olondola kwambiri amagwiritsidwa ntchito kwambiri m'magawo omwe amafunikira kuwongolera bwino, mongarobotics, mlengalenga, ndi zida zamankhwala. Mu ma robotics, amagwiritsidwa ntchito polumikizana ndi ma actuators kuti awonetsetse kuti akuyenda bwino komanso kugwira molondola.

Mu ma drone gimbals, ma servos olondola kwambiri amathandiza kukhazikika makamera, zomwe zimapangitsa zithunzi zomveka bwino. Kuphatikiza apo, makatani odziwikiratu ndi makamera achitetezo m'nyumba zanzeru amadalira kulondola kwa servo kuti agwire bwino ntchito.

Muzochitika izi, kulondola kumagwirizana mwachindunji ndi chitetezo cha dongosolo ndi mphamvu. Mwachitsanzo,mu maloboti azachipatala, ngakhale zolakwika zazing'ono zimatha kuyambitsa kulephera kwa opaleshoni, chifukwa chake ndikofunikira kusankha ma servos odalirika kwambiri, odalirika kwambiri.Kumvetsetsa izi kungakuthandizeni kukonza bwino mapulojekiti anu ndikusankha mitundu yoyenera ya servo kuti muwongolere magwiridwe antchito.
