Makina odulira a laser amayendetsedwa makamaka ndi injini. Makasitomala ena amakumana ndi zisankho akamasintha makina odulira fiber laser. Kodi ndi kusankha servo motor kapena stepper motor? Opanga makina odulira laser amatha kusanthula kusiyana pakati pa njira ziwiri zosiyana zoyendetsera, Choyamba, tiyenera kumvetsetsa kusiyana pakati pa servo motor ndi stepper motor yosankhidwa ndi makina odulira laser:
Servo motor ndi stepper motor zitha kugwiritsidwa ntchito kuyendetsa makina odulira laser, makampani ambiri amasankha makina odulira laser, chifukwa chiyani? Servo motor ili ndi phokoso lochepa komanso kulondola kwambiri. AC servo motor imagwiritsidwa ntchito ngati chipangizo choyendetsera, chomwe chingapangitse kuti pakhale njira yowongolera yolondola kwambiri komanso yogwira ntchito bwino kwambiri monga DC servo motor. Chifukwa cha kapangidwe ka AC servo motor kopanda burashi, palibe kukonza, voliyumu yaying'ono, yothandiza kuti liwiro ndi mphamvu ziwonjezeke. Pakadali pano, DC servo motor yasinthidwa kukhala makina ambiri a digito AC servo system pogwiritsa ntchito microprocessor yothamanga kwambiri ndi purosesa yapadera ya digito (DSP), hardware servo control yoyambirira yalowa mu pulogalamu yowongolera servo, ma algorithms ena apamwamba mu chiphunzitso chamakono chowongolera akwaniritsidwa, kenako amasintha kwambiri magwiridwe antchito a servo system, kotero servo unit imatha kusintha kwambiri magwiridwe antchito ndi kulondola kwa makina, koma mtengo wa servo drive unit nawonso ndi wokwera. Ndi kusintha pang'onopang'ono kwa ukadaulo wowongolera servo, servo drive unit ikukhala mphamvu yayikulu ya drive unit, ndipo mtengo wa servo drive unit ukuchepa pang'onopang'ono.
Pali mitundu iwiri ya ma servo driver. Chimodzi chimagwiritsa ntchito pulse control. Mtundu uwu wa driver umatseka kuzungulira ndi mota, koma subwerera ku CNC system. Wina umagwiritsa ntchito voltage control mode, kudzera mu voltage ya motor speed control, chizindikiro cha motor feedback kudzera mu driver feedback kupita ku CNC system kuti chiwongolere malo.
Posankha galimoto yoyendetsera, ndikofunikiranso kuganizira kuchuluka kwa mtengo wa galimoto yoyendetsera mu chida chonse cha makina a NC, mtengo wotsika wa chida chonse cha makina a CNC nthawi zambiri umasankha galimoto yoyendetsa ya stepper, ndipo mtengo wapamwamba wa chida cha makina umasankha galimoto yoyendetsa ya servo. Komabe, posankha galimoto yoyendetsera, vuto lofanana pakati pa galimoto yoyendetsera ndi makina a CNC liyeneranso kuganiziridwa. Posankha makina owongolera a closed-loop, galimoto yoyendetsa ya servo yotsekedwa iyenera kusankhidwa. Makina a AC servo ndi apamwamba kuposa mota ya stepper pazinthu zambiri zogwirira ntchito.
