Kodi mukudziwa kusiyana pakati pa stepper motor ndi servo motor?

Servo motere
1, mfundo yogwira ntchito
Ma motors awiriwa ndi osiyana kwambiri, ma stepper motor ndiye siginecha yamagetsi yamagetsi kupita kumalo osasunthika kapena kusuntha kwa mzere wagawo lotseguka loyang'anira gawo la stepper motor, onani mfundo yogwirira ntchito ya stepper motor.

Ndipo servo makamaka amadalira kugunda kwa malo, servo motor palokha ali ndi ntchito yotumiza pulses, kotero servo galimoto iliyonse kasinthasintha wa ngodya, adzatumiza nambala yofananira ya pulses, kotero kuti, ndi servo galimoto kuvomereza kugunda anapanga echo, kapena kuzungulira kuzungulira, kotero kuti dongosolo adzakhala momveka bwino zingati kuti pulses kulamulira anatumiza ndi kubweza zolondola. kuti akwaniritse malo olondola.

2, Kuwongolera kulondola
Kulondola kwa mota ya stepper nthawi zambiri kumatheka ndi kuwongolera kolondola kwa masitepe, omwe amakhala ndi magiya ambiri ogawa kuti athe kuwongolera bwino.

Kuwongolera kulondola kwa mota ya servo kumatsimikiziridwa ndi encoder yozungulira kumbuyo kwa shaft yamoto, ndipo kuwongolera kulondola kwa servo motor nthawi zambiri kumakhala kokwera kuposa kwa stepper motor.

3, Liwiro ndi kuchuluka kwachulukidwe
Stepper galimoto mu ntchito otsika-liwiro sachedwa kugwedera otsika-pafupipafupi, kotero pamene stepper galimoto ntchito otsika-liwiro, kawirikawiri ayeneranso kugwiritsa ntchito damping luso kugonjetsa chodabwitsa cha otsika pafupipafupi kugwedera, monga kuwonjezera dampers pa galimoto kapena galimoto ntchito magawano luso, etc. ntchito yothamanga kwambiri kuti musunge magwiridwe antchito abwino kwambiri. Mawonekedwe amphindi amafupikitsa a awiriwa ndi osiyana, ndipo nthawi zambiri liwiro la injini ya servo ndi lalikulu kuposa la stepper motor.

Ma torque a motor stepper amachepetsa pomwe liwiro limachulukira, pomwe servo mota imakhala yotulutsa nthawi zonse, motero mota ya stepper nthawi zambiri imakhala yopanda mphamvu, pomwe mota ya AC servo imakhala ndi mphamvu zambiri.

4. Kuthamanga ntchito
Ma motors a Stepper nthawi zambiri amakhala otseguka-loop control, pakakhala kuchuluka kwambiri koyambira kapena kuchulukirachulukira kudzakhala kopanda mayendedwe kapena plugging chodabwitsa, kotero kugwiritsa ntchito kufunikira kothana ndi zovuta za liwiro kapena kukulitsa encoder yotseka-loop control, onani chomwe chili chotseka-loop stepper mota. Ngakhale ma servo motors amagwiritsa ntchito kuwongolera kotseka, kosavuta kuwongolera, palibe kutayika kwa zochitika.

 5. Mtengo

Magalimoto a Stepper ndi opindulitsa potengera mtengo wamtengo, kuti akwaniritse ntchito yomweyo ngati mtengo wagalimoto ya servo ndi wamkulu kuposa mphamvu yofananira yamagetsi, kuyankha kwakukulu kwa servo motor, kuthamanga kwambiri komanso ubwino wolondola kwambiri zimatsimikizira mtengo wokwera wa chinthucho, chomwe ndi chosapeweka.

Mwachidule, ma stepper motors ndi ma servo motor onse kuchokera ku mfundo yogwirira ntchito, kuwongolera kulondola, kuchuluka kwachulukidwe, magwiridwe antchito ndi mtengo pali kusiyana kwakukulu. Koma awiriwa ali ndi ubwino wawo, ogwiritsa ntchito omwe akufuna kusankha kuchokera kwa iwo ayenera kuphatikiza zosowa zawo zenizeni ndi zochitika zogwiritsira ntchito.
