Stepper motorndi injini yotsegula yotsegula yomwe imatembenuza ma pulse amagetsi kukhala ma aang'ono kapena mizere, ndipo ndiye chinthu chachikulu chothandizira pamadongosolo amakono a digito, omwe amagwiritsidwa ntchito kwambiri. Chiwerengero cha ma pulses chikhoza kuwongoleredwa kuti chiwongolere kusamuka kwa angular kuti akwaniritse malo olondola; nthawi yomweyo, kugunda pafupipafupi kumatha kuwongoleredwa kuwongolera kuthamanga ndi kuthamangitsa kwa kasinthasintha wamagalimoto kuti akwaniritse cholinga chowongolera liwiro. Nthawi zambiri, njira yodziwika bwino yopezera mizere yolondola ndiyo kulumikiza chowongolera chowongolera ndi sliding screw vice polumikizana ndi makina owongolera, omwe amasintha kuyenda kozungulira kukhala koyenda mzere kudzera pakulumikizana kwa ulusi ndi mtedza.
Linear stepper motor imagwiritsa ntchito ukadaulo wapamwamba kwambiri kuti aphatikizire screw sub ndi stepper motor mugawo limodzi, kotero kuti makasitomala safunikira kuyika zolumikizirana akamagwiritsa ntchito, zomwe sizimangopulumutsa malo oyika, komanso zimatha kupititsa patsogolo luso la msonkhano wamakina. Ma Linear stepper motors amatha kugawidwa m'mitundu inayi molingana ndi kapangidwe kake: mtundu wagalimoto wakunja, mtundu wosagwidwa, mtundu wa shaft wokhazikika ndi slider linear motor.
Nkhaniyi ikufotokoza za kamangidwe ka Non-captivelinear stepper motorsndipo potsiriza akufotokoza ubwino wake ntchito.
Mfundo ya Non-captive linear stepper motor
Wosagwidwalinear stepper motoramaphatikiza nati ndi chozungulira cha mota kukhala gawo limodzi, ndi tsinde lodutsa pakati pa chozungulira cha mota. Ikagwiritsidwa ntchito, ndodo ya filament imakhazikika ndikupangitsa kuti ikhale yotsutsana ndi kuzungulira, ndipo injini ikayatsidwa ndi rotor imazungulira, injiniyo imayendetsa motsatira ndodo ya filament. Mosiyana ndi zimenezo, ngati galimotoyo itakhazikika ndipo ndodo ya filament imachita anti-rotation nthawi imodzi, ndiye kuti ndodo ya filament imayenda mozungulira.
Ubwino wogwiritsa ntchito ma Non-captive linear stepper motors
Mosiyana ndi zochitika zomwe zimayendetsedwa ndi ma stepper motors omwe amayendetsedwa ndikunja amagwiritsidwa ntchito ndi maupangiri amizere, ma Non-captive linear stepper motors ali ndi mwayi wawo wapadera, womwe umawonetsedwa m'magawo atatu otsatirawa.
Imalola kuti pakhale vuto lalikulu loyika dongosolo.
Nthawi zambiri, ngati chiwongolero chakunja choyendetsedwa ndi stepper motor chikugwiritsidwa ntchito, pamakhala chiwopsezo chachikulu cha kuyimitsidwa kwadongosolo ngati ulusi ndi kalozera sizimayikidwa mofanana. Komabe, ndi Non-captive linear stepper motors, vuto lakuphali limatha kusintha kwambiri chifukwa cha mawonekedwe ake, omwe amalola kulakwitsa kwakukulu pamakina.
Osadalira liwiro lovuta la ndodo ya filament.
Pamene galimoto yoyendetsedwa ndi mzere wa stepper imasankhidwa kuti ikhale yothamanga kwambiri, nthawi zambiri imachepetsedwa ndi liwiro lovuta la ndodo ya filament. Komabe, ndi Non-captive linear stepper motor, filament bar imakhazikika ndipo imapangidwa kuti ikhale yotsutsana ndi kuzungulira, kulola galimotoyo kuyendetsa slider ya kalozera wa mzere. Popeza screw ndi yoyima, sichimangokhala ndi liwiro lovuta la screw mukapeza liwiro lalikulu.
Kuyika kosunga malo.
Ma motor stepper motor omwe sali ogwidwa, chifukwa cha mtedza wake womangidwira mkati mwa kapangidwe kake ka injini, sikhala ndi malo owonjezera kupitilira kutalika kwa screw. Ma motors angapo amatha kukhazikitsidwa pa screw yomweyi, ndipo ma motors sangathe "kupyola" wina ndi mzake, koma mayendedwe awo ndi odziyimira pawokha. Chifukwa chake, ndiye chisankho chabwino kwambiri pamapulogalamu omwe malo amafunikira kwambiri.
