Zvinonyatsozivikanwa mumunda weinjiniya kuti kushivirira kwemuchina kune mhedzisiro yakakura pakurongeka uye kurongeka kwemhando yega yega yemudziyo unofungidzira zvisinei nekushandiswa kwayo. Izvi ndezvechokwadiwo nezvestepper motors. Semuyenzaniso, yakajairwa yakavakirwa stepper mota ine yekushivirira nhanho inosvika ± 5 muzana kukanganisa padanho. Aya ndiwo asiri-accumulative zvikanganiso nenzira. Mota zhinji dze stepper dzinofambisa madhigirii 1.8 padanho, izvo zvinoita kuti pave nekukanganisa kusingaite 0.18 madhigirii, kunyangwe tiri kutaura nezve 200 nhanho pakutenderera (ona Mufananidzo 1).

Miniature Steping yeAccuracy
Iine mwero, isiri-cumulative, kurongeka kwe ± 5 muzana, yekutanga uye ine musoro nzira yekuwedzera kurongeka ndeye micro nhanho mota. Micro stepping inzira yekudzora ma stepper motors ayo anowana kwete chete kugadziriswa kwepamusoro asi kufamba kwakapfava nekumhanya kwakaderera, izvo zvinogona kubatsira zvikuru mune mamwe maapplication.
Ngatitange neyedu 1.8-degree nhanho angle. Iyi nhanho kona inoreva kuti sezvo mota inononoka nhanho imwe neimwe inova chikamu chikuru chese. Pakunonoka uye kunonoka kumhanya, iyo yakakura nhanho saizi inokonzera cogging mumotokari. Imwe nzira yekudzikisa uku kutsetseka kwekushanda nekumhanya kunononoka kudzikisa saizi yenhanho yega yega mota. Apa ndipo apo micro stepping inova imwe yakakosha imwe nzira.
Micro stepping inowanikwa nekushandisa pulse-width modulated (PWM) kudzora ikozvino kune mota windings. Chii chinoitika ndechekuti mutyairi wemota anoendesa maviri voltage sine mafungu kune mota windings, imwe neimwe iri 90 degrees kunze kwechikamu neimwe. Saka, nepo iko zvino ichiwedzera mune imwe inomonereka, inodzikira mune imwe inomonereka kuti ibudise zvishoma nezvishoma kufambisa kwezvino, izvo zvinoguma nekufamba kwakapfava uye kunoenderana kugadzirwa kwe torque pane yaanowana kubva kune yakajairwa nhanho yakazara (kana kunyange yakajairika hafu nhanho) kutonga. (ona Mufananidzo 2).
single-axisstepper mota controller + mutyairi anoshanda
Kana uchifunga nezve kuwedzera kwechokwadi kunoenderana neiyo micro stepping control, mainjiniya anofanirwa kufunga kuti izvi zvinokanganisa sei mamwe maitiro emota. Nepo kutsvedzerera kwekuburitsa torque, kudzika-kumhanya kufamba, uye resonance inogona kuvandudzwa uchishandisa micro stepping, zvakajairwa zvipimo mukutonga uye dhizaini yemotokari inovadzivirira kubva pakusvika kwavo kwakaringana maitiro. Nekuda kwekushanda kweiyo stepper mota, micro stepping dhiraivha inogona kungo enzanisa yechokwadi sine wave. Izvi zvinoreva kuti imwe torque ripple, resonance, uye ruzha zvicharamba zviri muhurongwa kunyangwe imwe neimwe yeiyi yakadzikiswa zvakanyanya mukuita micro stepping operation.
Mechanical Accuracy
Imwe gadziriso yemechani kuti uwane huchokwadi mune yako stepper mota ndeye kushandisa diki inertia mutoro. Kana iyo motokari yakasungirirwa kune inertia huru painoedza kumira, mutoro wacho uchaita kuti zvimwe zvishoma zvishoma-kutenderera. Nekuti ichi kazhinji chikanganiso chidiki, iyo mota controller inogona kushandiswa kuigadzirisa.
Pakupedzisira, tinodzokera kune mutongi. Iyi nzira inogona kutora imwe nhamburiko yeinjiniya. Kuti uvandudze huroyi, ungangoda kushandisa controller yakanyatsogadzirirwa mota yawakasarudza kushandisa. Iyi inzira chaiyo yekubatanidza. Izvo zvirinani kugona kwemutongi kushandisa mota ikozvino nemazvo, ndiko kuwedzera kwakaringana kwaunokwanisa kuwana kubva kune inotsika mota yauri kushandisa. Izvi zvinodaro nekuti iyo controller inoronga chaizvo kuti yakawanda sei ikozvino iyo mota windings inogamuchira kuti itange kutsika.
Kurongeka mumafambiro masisitimu chinhu chinowanzodiwa zvichienderana nekushandisa. Kunzwisisa kuti stepper system inoshanda sei pamwe chete kugadzira iyo chaiyo inobvumira mainjiniya kuti atore mukana wetekinoroji iripo, kusanganisira iyo inoshandiswa mukugadzira zvinhu zvemuchina wemota yega yega.
