Kuyesa ma servos sikufuna chidziwitso chapamwamba chamagetsi. Kudziwa njira zingapo zosavuta komanso zothandiza kumakupatsani mwayi wowunika momwe amagwirira ntchito.

Chifukwa Chiyani Mumayesa Ma Servo?
Ma Servo ali ndi ma mota, ma gear seti, ma potentiometers, ndi ma control circuitry. Vuto lililonse la zigawozi lingayambitse servo kuti isagwire ntchito. Mwachitsanzo, ma loboti amatha kupanikizana mwadzidzidzi, kapena galimoto yakutali ikhoza kusalabadira; nthawi zambiri, izi zimachitika chifukwa cha kulephera kwa servo. Kuyezetsa koyambirira kumalepheretsa kuti mavuto adziwike pakati pa polojekiti, ndikupulumutsa nthawi ndi khama.

Kuyesa kumakuthandizani kumvetsetsa momwe servo imagwirira ntchito. Ma servos ena amatha kutembenuka, koma amatha kukhala ndi zovuta monga torque yosakwanira, kuyika pakati kolakwika, kapena phokoso lambiri. Ndi kuyesa mwadongosolo, mutha kusankha ma servos ochita bwino kwambiri pama projekiti ovuta ndikugwiritsa ntchito amphamvu pang'ono pazinthu zosafunikira kwambiri, kukulitsa kugwiritsa ntchito bwino zinthu.

Momwe Mungayesere Servo Motor ndi Multimeter
Multimeter ndi chida chothandizira kuyesa kukhulupirika kwa ma servo motor circuitry. Khazikitsani ma multimeter pamalo okanira ndikuyesa kukana pakati pa terminal yamagetsi ya servo motor ndi nthaka. Nthawi zambiri, kukana uku kuyenera kukhala mazana angapo mpaka masauzande angapo ohms. Ngati kukana kuli zero kapena kopanda malire, pali kuthekera kwakukulu kuti kuzungulira kwamkati kumakhala kofupikitsa kapena kotseguka.

Kenaka, yesani kukana pakati pa mzere wa chizindikiro ndi nthaka. Kukana kumeneku nthawi zambiri kumakhala kokwera kwambiri mphamvu ikazima. Ngati dera lalifupi likupezeka, limasonyeza kuti chipangizo chowongolera chikhoza kuwonongeka. Ngakhale ma multimeter sangathe kutsanzira momwe servo motor ikugwirira ntchito, imatha kuthetsa zolakwika zazikulu zamagawo, makamaka mukakhala ndi gulu la ma servo omwe amafunikira kuwunika koyambirira. Njira imeneyi ndi yothandiza kwambiri.

Zomwe Muyenera Kusamala Pamayeso a Servo No-Load
Kuyesa kopanda katundu kumachitidwa pamene servo sichikugwirizana ndi katundu uliwonse. Mphamvu ikayatsidwa, tumizani pang'onopang'ono zowongolera ku servo ndikuwona ngati kuzungulira kwake kuli kosalala. Servo yathanzi iyenera kusinthasintha bwino popanda kugwedezeka kapena phokoso lachilendo, ndikutha kuyima molondola pamalo omwe mwasankhidwa.

Samalani kwambiri kulondola kwa kubwerera kwa servo pakati. Sunthani servo kuchokera kumanzere kwake chakumanzere kupita kumanja kwake kopitilira muyeso, ndiyeno perekani lamulo kuti muyibwezere pakatikati. Onani ngati ikhoza kubwereranso pamalo omwewo nthawi iliyonse. Ngati pali vuto lalikulu pakubwerera pakati, ndizotheka kuti potentiometer yamkati yavala kapena giya backlash ndi yayikulu kwambiri. Servo yotere si yoyenera ku mapulogalamu omwe amafunikira kuyika bwino.

Njira Yolondola Yoyezetsa Katundu wa Servo
Kuwunika momwe ntchito ya servo ikugwirira ntchito imatha kutheka kudzera pakuyesa katundu. Mutha kutsina pang'onopang'ono servo disc ndi zala zanu kuti mumve mphamvu pa shaft ya servo. Servo yogwira ntchito bwino iyenera kukana kukana pang'ono ndikusunga malo ake. Ngati mphamvu yaying'ono imapangitsa servo kutaya malo ake kapena kusiya kuzungulira, zikuwonetsa torque yosakwanira.

Njira yodziwika bwino ndiyo kugwiritsa ntchito sikelo ya kasupe kapena chida cha lever mkono poyesa kuchuluka kwake. Jambulani torque yayikulu ya servo pansi pamikhalidwe yosiyanasiyana yamagetsi ndikuyerekeza ndi mtengo wadzina. Poyesa, samalani kuti musalole kuti servo ikhale yoyimitsidwa kwa nthawi yayitali, chifukwa kuchuluka kwamagetsi kumatha kuwononga mota kapena kuyendetsa mayendedwe.

Kodi phokoso lachilendo ndi kugwedezeka mu servo kumasonyeza chiyani?

Ma alarm omwe akuwonetsa zovuta zamkati m'ma servo motors nthawi zambiri amatsagana ndi phokoso lalikulu kwambiri. Magiya owonongeka kapena zinthu zakunja zomwe zayikidwamo nthawi zambiri zimatulutsa mawu omveka bwino a "kudina", pomwe mphamvu yochulukirapo pagalimoto kapena kuvula zida kungayambitse kung'ung'udza kosamveka. Kusokonekera kwa potentiometer kapena kuwongolera kosakhazikika nthawi zambiri kumawonetsa phokoso lakugwedezeka kosalekeza.

Jitter ndi chinthu chokhudza kwambiri. Ngati mutu wa servo ukuyenda mosalekeza mkati mwazocheperako, zitha kuwonetsa kusagwirizana kwa magawo a PID kapena cholakwika pamachitidwe oyankha. Pachifukwa ichi, ngakhale servo ingakhale yozungulira, siigwira ntchito mokhazikika pazochitika zenizeni, makamaka pamapulojekiti apamwamba kwambiri a robotics kapena gimbal kamera. Ma servos oterowo amafunikira kusinthidwa kapena kukonzedwa.

Njira Zotetezera Pakuyesa Magalimoto a Servo
Poyesa ma servos, nthawi zonse fufuzani kuti polarity yamagetsi yalumikizidwa molondola komanso kuti palibe kulumikizana kobwerera. Ngakhale kutembenuka kwa sekondi imodzi kwa magetsi kumatha kuwononga chip cha servo motor control. Mukamagwiritsa ntchito magetsi osinthika, yambani ndi voteji yotsika ndikuwonjezera pang'onopang'ono kuti mupewe kuthamanga kwadzidzidzi kuti zisawononge zida zamagetsi zamagetsi.

Poyesa, samalani kwambiri ndi kutentha kwa servo. Kutentha pang'ono ndikwachilendo; Komabe, ngati servo ikhala yotentha kwambiri pakangopita nthawi yochepa, chotsani mphamvuyo ndikuyiyang'ana. Izi zimachitika kwambiri chifukwa cha kufupika kwa koyilo yamkati kapena kukana kwamakina komwe kumayambitsa kupindika. Pakuyesa kotalikirako, tikulimbikitsidwa kugwiritsa ntchito njira yapakatikati kuti mulole nthawi yoziziritsa ya servo, potero ikukulitsa moyo wake.
