Linear stepper motor, yomwe imadziwikanso kutilinear stepper motor, ndi maginito ozungulira pachimake polumikizana ndi pulsed electromagnetic field yopangidwa ndi stator kuti ipange mozungulira, linear stepper motor mkati mwa mota kuti isinthe kusuntha kozungulira kukhala koyenda mzere. Ma Linear stepper motors amatha kuyenda mozungulira kapena kuzungulira mozungulira molunjika. Ngati mota yozungulira imagwiritsidwa ntchito ngati gwero lamphamvu kuti isinthidwe kukhala mizere yozungulira, magiya, zida zamakamera ndi makina monga malamba kapena mawaya amafunikira. Kuyamba koyamba kwa linear stepper motors kunali mu 1968, ndipo chithunzi chotsatirachi chikuwonetsa ma motors ena ofanana ndi ma stepper.
Mfundo yoyambira yamakina oyendera kunja
Rotor ya motor Linear stepper motor ndi maginito okhazikika. Pamene mafunde akuyenda mu stator mafunde, ndi stator mapiringidzo amapanga vekitala maginito mphamvu. Mphamvu ya maginito imeneyi imayendetsa rotor kuti izungulire pa ngodya inayake, kotero kuti njira ya maginito a rotor imagwirizana ndi mphamvu ya maginito ya stator. Pamene vekitala ya stator ya maginito imazungulira ndi ngodya. Rotor imazunguliranso pakona ndi mphamvu ya maginito iyi. Pakulowetsa kulikonse kwamagetsi, rotor yamagetsi imazungulira ndi ngodya imodzi ndikusuntha sitepe imodzi patsogolo. Imatulutsa kusamuka kwa angular molingana ndi kuchuluka kwa ma pulses ndi liwiro lolingana ndi ma frequency a pulse. Kusintha kwa dongosolo la mphamvu zokhotakhota kumatembenuza injini. Chifukwa chake kusinthasintha kwa ma stepper motor kumatha kuwongoleredwa ndikuwongolera kuchuluka kwa ma pulses, ma frequency ndi dongosolo la kupatsa mphamvu ma windings a mota pagawo lililonse.
Motowo umagwiritsa ntchito wononga ngati nsonga yotuluka, ndipo nati yagalimoto yakunja imalumikizidwa ndi wononga kunja kwa mota, kutengera njira yoletsa wononga kuti zisatembenukire wachibale wina ndi mzake, motero zimatheka kuyenda mozungulira. Zotsatira zake ndi mawonekedwe osavuta omwe amalola kugwiritsa ntchito ma Linear stepper motors molunjika kuti aziyenda bwino pamapulogalamu ambiri popanda kuyika kulumikizana kwamakina akunja.
Ubwino wa ma motors oyendetsedwa ndi kunja
Ma motors olondola a linear screw stepper amatha kusintha masilinda mkatimapulogalamu ena, kupeza zabwino monga kuyika bwino, liwiro lowongolera, komanso kulondola kwambiri. Ma Linear screw stepper motors amagwiritsidwa ntchito pazinthu zosiyanasiyana kuphatikiza kupanga, kusanja bwino, kuyeza kwamadzimadzi, kuyenda bwino, ndi madera ena ambiri omwe ali ndi zofunikira kwambiri.
▲Kulondola kwambiri, kubwereza kobwerezabwereza mpaka ± 0.01mm
Linear screw stepping motor imachepetsa vuto la interpolation lag chifukwa cha njira yosavuta yopatsira, kulondola kwa malo, kubwerezabwereza komanso kulondola kwenikweni. Ndikosavuta kukwaniritsa kuposa "rotary motor + screw". Kubwereza kwa malo olondola a wononga wamba wa liniya screw stepping motor kumatha kufika ± 0.05mm, ndipo kubwereza kubwereza kulondola kwa wononga mpira kumatha kufika ± 0.01mm.
▲ Kuthamanga kwambiri, mpaka 300m/min
Liwiro la linear screw stepping motor ndi 300m/min ndipo mathamangitsidwe ndi 10g, pomwe liwiro la wononga mpira ndi 120m/mphindi ndipo mathamangitsidwe ndi 1.5g. Ndipo kuthamanga kwa liniya screw stepping motor kudzakhala bwino pambuyo pothana bwino ndi vuto la kutentha, pomwe "rotary Liwiro la "servo motor & ball screw" liri ndi liwiro lochepa, koma ndizovuta kusintha zina.
Moyo wapamwamba komanso kukonza kosavuta
Linear screw stepping motor ndi yoyenera kulondola kwambiri chifukwa palibe kulumikizana pakati pa magawo osuntha ndi magawo osasunthika chifukwa cha mpata wokwera komanso osavala chifukwa cha liwiro lalikulu lobwerezabwereza la zosuntha. Mpikisano wa mpira sungathe kutsimikizira kulondola mumayendedwe othamanga kwambiri, ndipo kukangana kothamanga kwambiri kumayambitsa kuvala kwa screw nut, zomwe zingakhudze kulondola kwa kayendetsedwe kake ndipo sizingakwaniritse kufunikira kolondola kwambiri.
Kusankhidwa kwa motor drive yakunja
Popanga zinthu kapena mayankho okhudzana ndi mizere, timalimbikitsa mainjiniya kuti ayang'ane mfundo zotsatirazi.
1. Kodi katundu wa dongosolo ndi chiyani?
Katundu wamakinawa amaphatikizapo katundu wokhazikika komanso mphamvu zosunthika, ndipo nthawi zambiri kukula kwa katundu kumatsimikizira kukula kwa injini.
Static katundu: kukankhira kwakukulu komwe screw imatha kupirira popuma.
Mphamvu yamphamvu: kukankhira kwakukulu komwe screw imatha kupirira ikamayenda.
2. Kodi liniya likuthamanga liwiro la mota ndi chiyani?
Liwiro lothamanga la liniya motor limagwirizana kwambiri ndi kutsogolera kwa screw, kutembenuka kumodzi kwa screw ndi chitsogozo chimodzi cha nati. Kwa liwiro lotsika, ndi bwino kusankha screw ndi chowongolera chaching'ono, komanso kuthamanga kwambiri, ndikofunikira kusankha screw yayikulu.
3. Kodi kufunikira kolondola kwadongosolo ndi chiyani?
Kulondola kwa screw: kulondola kwa wononga nthawi zambiri kumayesedwa ndi kulondola kwa mzere, mwachitsanzo, cholakwika pakati pa ulendo weniweni ndi ulendo wamalingaliro pambuyo poti wonongayo izungulira kuzungulira kowuma kowawa.
Bweretsani kulondola kwa malo: kubwereza kubwereza kulondola kumatanthauzidwa ngati kulondola kwa dongosolo kuti athe kufika pa malo otchulidwa mobwerezabwereza, chomwe chiri chizindikiro chofunikira pa dongosolo.
Kubwerera m'mbuyo: Kubwereranso kwa wononga ndi nati pakupumula pamene ma axial achibale awo amasunthika. Pamene nthawi yogwira ntchito ikuwonjezeka, kubwereranso kudzawonjezeka chifukwa cha kuvala. Kulipila kapena kuwongolera kwa backlash kutha kupezedwa ndi mtedza wochotsa mmbuyo. Pamene ma bi-directional positioning akufunika, backlash ndi nkhawa.
4. Zosankha zina
Nkhani zotsatirazi zikuyeneranso kuganiziridwa posankha: Kodi kukwera kwa mzere wa stepper motor molingana ndi kapangidwe ka makina? Kodi mungalumikize bwanji chinthu chosuntha ndi nati? Kodi stroko yabwino ya screw rod ndi iti? Ndi mtundu wanji wa drive womwe ungafanane?
