Injini yoyendera ma stepper, yomwe imadziwikanso kuti Linear stepper motormota yoyendera yolunjika, ndi magnetic rotor core polumikizana ndi pulsed electromagnetic field yopangidwa ndi stator kuti ipange rotation, linear stepper motor mkati mwa mota kuti isinthe rotary motion kukhala linear motion. Linear stepper motors zimatha kuchita linear motion kapena linear reciprocating motion mwachindunji. Ngati rotary motor ikugwiritsidwa ntchito ngati gwero lamphamvu kuti isinthe kukhala linear motion, magiya, kapangidwe ka cam ndi njira monga malamba kapena mawaya amafunika. Kuyambitsidwa koyamba kwa linear stepper motors kunali mu 1968, ndipo chithunzi chotsatirachi chikuwonetsa ma linear stepper motors wamba.
Mfundo yoyambira ya ma mota oyenda molunjika oyendetsedwa kunja
Chozungulira cha mota yoyendera ya mzere wolunjika ndi maginito okhazikika. Mphamvu ikamayenda kudzera mu stator winding, stator winding imapanga vector magnetic field. Magnetic field iyi imayendetsa rotor kuti izungulire pa ngodya inayake, kotero kuti malangizo a maginito awiri a rotor agwirizane ndi malangizo a stator magnetic field. Pamene stator's vector magnetic field izungulira pa ngodya. Rotor imazunguliranso pa ngodya ndi maginito awa. Pa kulowetsa kulikonse kwamagetsi, rotor yamagetsi imazungulira pa ngodya imodzi ndikupita patsogolo. Imatulutsa kusuntha kwa angular molingana ndi kuchuluka kwa ma pulses input ndi liwiro lofanana ndi ma pulse frequency. Kusintha dongosolo la winding energization kumabwezera mmbuyo mota. Chifukwa chake kuzungulira kwa mota yoyendera kumatha kulamulidwa powongolera kuchuluka kwa ma pulses, ma frequency ndi dongosolo la mphamvu ya ma motor windings a gawo lililonse.
Mota imagwiritsa ntchito screw ngati axis yotuluka, ndipo nati yoyendetsera yakunja imalumikizidwa ndi screw kunja kwa mota, zomwe zimapangitsa kuti nati yoyendetserayo isatembenuke kuti igwirizane, zomwe zimapangitsa kuti iyende molunjika. Zotsatira zake ndi kapangidwe kosavuta komwe kamalola kugwiritsa ntchito ma motors oyenda molunjika mwachindunji kuti ayende molunjika m'njira zambiri popanda kuyika kulumikizana kwakunja kwa makina.
Ubwino wa ma mota oyenda molunjika oyendetsedwa ndi kunja
Ma mota oyendera ma screw stepper a Precision linear amatha kusintha ma silinda mumapulogalamu ena, kupeza zabwino monga malo olondola, liwiro lowongolera, komanso kulondola kwambiri. Ma mota oyendera screw stepper amagwiritsidwa ntchito m'njira zosiyanasiyana kuphatikizapo kupanga, kuwerengera molondola, kuyeza madzi molondola, kuyenda molondola kwa malo, ndi madera ena ambiri omwe ali ndi zofunikira kwambiri.
▲Kulondola kwambiri, kobwerezabwereza komwe kungathe kuyikidwa mpaka ± 0.01mm
Mota yoyendera screw stepping imachepetsa vuto la kuchedwa kwa interpolation chifukwa cha njira yosavuta yotumizira, kulondola kwa malo, kubwerezabwereza komanso kulondola kwathunthu. N'zosavuta kuchita kuposa "rotary motor + screw". Kulondola kwa malo obwerezabwereza kwa screw wamba wa mota yoyendera screw stepping kumatha kufika ± 0.05mm, ndipo kulondola kwa malo obwerezabwereza kwa screw mpira kumatha kufika ± 0.01mm.
▲ Liwiro lalikulu, mpaka 300m/mphindi
Liwiro la mota yoyendera screw ndi 300m/min ndipo kuthamanga ndi 10g, pomwe liwiro la screw ndi 120m/min ndipo kuthamanga ndi 1.5g. Ndipo liwiro la mota yoyendera screw lidzawongoleredwa kwambiri mutathetsa vuto la kutentha bwino, pomwe "kuthamanga kwa rotary kwa mota yoyendera servo ndi mpira" kuli ndi liwiro lochepa, koma n'zovuta kusintha kwambiri.
Moyo wautali komanso kukonza kosavuta
Mota yoyendera ya linear screw ndi yoyenera kulondola kwambiri chifukwa palibe kukhudzana pakati pa ziwalo zosuntha ndi ziwalo zokhazikika chifukwa cha kusiyana kwa malo oikira komanso palibe kuwonongeka chifukwa cha kuyenda kwa liwiro lapamwamba kwa zoyendetsa. Skurufu ya mpira singatsimikizire kulondola kwa kuyenda kwa liwiro lapamwamba, ndipo kukangana kwa liwiro lapamwamba kudzayambitsa kutopa kwa nati ya screw, zomwe zidzakhudza kulondola kwa kuyenda ndipo sizingakwaniritse kufunikira kwa kulondola kwambiri.
Kusankha mota yolunjika yakunja
Popanga zinthu kapena mayankho okhudzana ndi kuyenda kolunjika, tikupangira mainjiniya kuti aziganizira mfundo zotsatirazi.
1. Kodi katundu wa dongosololi ndi wotani?
Katundu wa dongosololi umaphatikizapo katundu wosasunthika ndi katundu wosinthasintha, ndipo nthawi zambiri kukula kwa katundu kumatsimikiza kukula koyambira kwa mota.
Kulemera kosasunthika: mphamvu yayikulu yomwe sikuru imatha kupirira ikapuma.
Mphamvu yothamanga: mphamvu yayikulu yomwe sikuru imatha kupirira ikamayenda.
2. Kodi liwiro loyendetsa mota ndi lotani?
Liwiro lothamanga la mota yolunjika limagwirizana kwambiri ndi lead ya screw, kuzungulira kamodzi kwa screw ndi lead imodzi ya nati. Pa liwiro lotsika, ndibwino kusankha screw yokhala ndi lead yaying'ono, ndipo pa liwiro lalikulu, ndibwino kusankha screw yayikulu.
3. Kodi kulondola kwa dongosololi n'kofunika bwanji?
Kulondola kwa sikuru: kulondola kwa sikuru nthawi zambiri kumayesedwa ndi kulondola kwa mzere, mwachitsanzo cholakwika pakati pa ulendo weniweni ndi ulendo wongoganizira pambuyo poti sikuru yazungulira kuti ikhale bwalo louma lowawa.
Kulondola kwa malo obwerezabwereza: kulondola kwa malo obwerezabwereza kumatanthauzidwa ngati kulondola kwa dongosolo kuti likwanitse kufika pamalo omwe latchulidwa mobwerezabwereza, chomwe ndi chizindikiro chofunikira pa dongosolo.
Kubwerera m'mbuyo: kubwerera m'mbuyo kwa screw ndi nati pamene pali kupumula pamene kuchuluka kwa axial relative relative kusunthika. Pamene nthawi yogwira ntchito ikuwonjezeka, kubwerera m'mbuyo kudzawonjezekanso chifukwa cha kuwonongeka. Kubwezera kapena kukonza kubwerera m'mbuyo kungapezeke ndi nati yochotsa kubwerera m'mbuyo. Ngati pakufunika malo awiri olunjika, kubwerera m'mbuyo ndi nkhani.
4. Zosankha zina
Nkhani zotsatirazi ziyeneranso kuganiziridwa posankha: Kodi kuyika mota ya stepper yolunjika kukugwirizana ndi kapangidwe ka makina? Kodi mungalumikize bwanji chinthu chosuntha ku nati? Kodi ndodo ya screw imagwira ntchito bwanji? Kodi ndi mtundu wanji wa drive womwe udzafanane?
