Kodi mukudziwa kusiyana pakati pa mota ya stepper ndi mota ya servo?

Servo motor
1, mfundo yogwirira ntchito
Ma mota awiriwa ndi osiyana kwambiri, mota ya stepper ndi chizindikiro chamagetsi chomwe chimalowa mu kusuntha kwa angular kapena kusuntha kwa mzere wa magawo a mota ya stepper, onani mfundo yogwirira ntchito ya mota ya stepper.

Ndipo servo imadalira kwambiri kugunda kwa mtima kuti ifike pamalo ake, servo motor yokha ili ndi ntchito yotumiza ma pulse, kotero servo motor iliyonse ikazungulira ngodya, idzatumiza kuchuluka kofanana kwa ma pulse, kotero kuti, ndipo servo motor kuti ivomereze kugunda kwa mtima ipange echo, kapena closed loop, kotero kuti dongosololi lidzadziwike bwino kuchuluka kwa ma pulse omwe adatumizidwa ndikulandira kuchuluka kwa ma pulse omwe adabwerera, kuti athe kuwongolera molondola kuzungulira kwa mota kuti akwaniritse malo olondola.

2, Kuwongolera molondola
Kulondola kwa mota ya stepper nthawi zambiri kumachitika chifukwa cha kuwongolera kolondola kwa ngodya ya sitepe, yomwe ili ndi magiya osiyanasiyana ogawa magawo kuti ikwaniritse kuwongolera kolondola.

Kulondola kwa kuwongolera kwa mota ya servo kumatsimikiziridwa ndi cholembera chozungulira kumapeto kwa shaft ya mota, ndipo kulondola kwa kuwongolera kwa mota ya servo nthawi zambiri kumakhala kokwera kuposa kwa mota yoyendera.

3, Liwiro ndi mphamvu yochulukira
Mota ya stepper ikagwira ntchito mothamanga pang'ono imakhala ndi kugwedezeka kwa ma frequency otsika, kotero pamene mota ya stepper ikugwira ntchito mothamanga pang'ono, nthawi zambiri imafunikanso kugwiritsa ntchito ukadaulo wopondereza kuti igonjetse vuto la kugwedezeka kwa ma frequency otsika, monga kuwonjezera ma dampers pa mota kapena drive pogwiritsa ntchito ukadaulo wogawa magawo, ndi zina zotero, pomwe mota ya servo si yomwe imachitika chifukwa cha izi, mawonekedwe ake owongolera otsekedwa amatsimikiza kuti ikugwira ntchito mothamanga kwambiri kuti isunge magwiridwe antchito abwino kwambiri. Makhalidwe a mphindi-ma frequency a awiriwa ndi osiyana, ndipo nthawi zambiri liwiro loyesedwa la mota ya servo ndi lalikulu kuposa la mota ya stepper.

Mphamvu yotulutsa ya mota ya stepper imachepa pamene liwiro likukwera, pomwe mota ya servo imakhala ndi mphamvu yotulutsa mphamvu yokhazikika, kotero mota ya stepper nthawi zambiri imakhala ndi mphamvu yodzaza kwambiri, pomwe mota ya AC servo imakhala ndi mphamvu yodzaza kwambiri.

4, Kuthamanga kwa ntchito
Ma mota a stepper nthawi zambiri amakhala otseguka-loop control, ngati ma frequency oyambira ali okwera kwambiri kapena katundu wamkulu kwambiri, sakhala wolondola kapena wolumikizidwa, kotero kugwiritsa ntchito kufunikira kothana ndi mavuto a liwiro kapena kuwonjezera encoder closed-loop control, onani chomwe chiri closed-loop stepper motor. Ngakhale ma mota a servo amagwiritsa ntchito closed-loop control, ndikosavuta kulamulira, palibe kutayika kwa step phenomenon.

 5, Mtengo

Stepper motor ndi yabwino pankhani ya mtengo wake, chifukwa mtengo wake ndi wapamwamba kuposa wa stepper motor, ndipo servo motor imayankha bwino, liwiro lake ndi ubwino wake ndi wolondola kwambiri, zomwe zimapangitsa kuti mtengo wake ukhale wokwera, zomwe sizingapeweke.

Mwachidule, ma stepper motors ndi ma servo motors onse kuyambira pa mfundo yogwirira ntchito, kulondola kwa kuwongolera, kuchuluka kwa mphamvu yogwiritsira ntchito, magwiridwe antchito ndi mtengo pali kusiyana kwakukulu. Koma awiriwa ali ndi zabwino zawo, ogwiritsa ntchito omwe akufuna kusankha kuchokera kwa iwo ayenera kuphatikiza zosowa zawo zenizeni ndi zochitika zogwiritsira ntchito.
