Linear stepper motor, tseem hu ualinear stepper lub cev muaj zog, yog ib tug sib nqus rotor tub ntxhais los ntawm kev cuam tshuam nrog lub mem tes electromagnetic teb generated los ntawm lub stator los tsim rotation, linear stepper lub cev muaj zog nyob rau hauv lub cev muaj zog los hloov rotary motion rau hauv linear tsab ntawv tsa suab. Linear stepper motors tuaj yeem ua cov lus tsa suab los yog cov kab lus sib txuas ncaj qha. Yog tias lub tshuab hluav taws xob tau siv los ua lub zog los hloov mus rau hauv cov lus tsa suab, lub zog, cov qauv cam thiab cov txheej txheem xws li siv cov hlua lossis cov xov hlau yuav tsum tau ua. Thawj qhov kev taw qhia ntawm linear stepper motors yog nyob rau hauv 1968, thiab cov duab hauv qab no qhia tau hais tias qee qhov raug linear stepper motors.
Lub hauv paus ntsiab lus ntawm kev tsav tsheb sab nraud linear motors
Lub rotor ntawm ib qho kev tsav tsheb tawm sab nraud yog cov hlau nplaum ruaj khov. Thaum tam sim no ntws los ntawm stator winding, lub stator winding generates ib vector magnetic teb. Qhov no magnetic teb tsav lub rotor tig ntawm ib lub kaum ntse ntse, yog li ntawd cov kev taw qhia ntawm lub rotor tus khub ntawm magnetic teb coincides nrog cov kev taw qhia ntawm lub stator lub magnetic teb. Thaum lub stator lub vector magnetic teb tig los ntawm lub kaum sab xis. Lub rotor kuj tig ntawm lub kaum sab xis nrog cov hlau nplaum no. Rau txhua qhov hluav taws xob mem tes input, hluav taws xob rotor tig los ntawm ib lub kaum sab xis thiab txav mus rau ib kauj ruam mus rau pem hauv ntej. Nws outputs angular displacement proportional rau tus naj npawb ntawm pulses input thiab ceev proportional rau lub mem tes zaus. Hloov qhov kev txiav txim ntawm winding energization reverses lub cev muaj zog. Yog li lub stepper lub cev muaj zog tig tuaj yeem tswj tau los ntawm kev tswj cov naj npawb ntawm pulses, zaus thiab qhov kev txiav txim ntawm energizing lub cev muaj zog windings ntawm txhua theem.
Lub cev muaj zog siv lub hau ntswj raws li cov axis tawm, thiab cov txiv ntoo sab nraud tau koom nrog cov ntsia hlau sab nraum lub cev muaj zog, ua qee txoj hauv kev los tiv thaiv cov ntsia hlau ntsia hlau los ntawm kev tig mus rau cov txheeb ze rau ib leeg, yog li ua tiav cov lus tsa suab. Qhov tshwm sim yog qhov tsim qauv yooj yim heev uas tso cai rau kev siv cov linear stepper motors ncaj qha rau cov lus tsa suab ncaj nraim hauv ntau daim ntawv thov yam tsis muaj kev teeb tsa ntawm ib qho kev sib txuas sab nraud.
Qhov zoo ntawm kev tsav tsheb sab nraud linear motors
Precision linear ntsia hlau stepper motors tuaj yeem hloov lub tog raj kheej hauvqee qhov kev siv, ua tiav qhov zoo xws li qhov tseeb qhov chaw, tswj tau nrawm, thiab qhov tseeb siab. Linear screw stepper motors yog siv nyob rau hauv ntau yam kev siv xws li kev tsim khoom, precision calibration, precision kua ntsuas, meej txoj hauj lwm txav, thiab ntau lwm qhov chaw nrog siab precision.
▲ High precision, repeatable positioning raug mus txog ± 0.01mm
Linear ntsia hlau stepping lub cev muaj zog txo qhov teeb meem ntawm interpolation lag vim qhov yooj yim kis mechanism, positioning raug, repeatability thiab meej tseeb. Qhov rov ua qhov tseeb ntawm cov ntsia hlau zoo tib yam ntawm cov ntsia hlau linear stepping lub cev muaj zog tuaj yeem ncav cuag ± 0.05mm, thiab rov ua qhov tseeb ntawm lub pob ntsia hlau tuaj yeem ncav cuag ± 0.01mm.
▲ Kev kub ceev, mus txog 300m / min
Qhov ceev ntawm linear ntsia hlau stepping lub cev muaj zog yog 300m / min thiab acceleration yog 10g, thaum lub ceev ntawm pob ntsia hlau yog 120m / min thiab acceleration yog 1.5g. Thiab qhov ceev ntawm linear ntsia hlau stepping lub cev muaj zog yuav raug txhim kho ntxiv tom qab ua tiav kev daws teeb meem thaum tshav kub kub, thaum lub "rotary" ceev ntawm "servo motor & pob ntsia hlau" yog txwv nyob rau hauv ceev, tab sis nws yog ib qho nyuaj rau txhim kho ntau.
Lub neej siab thiab kev saib xyuas yooj yim
Lub linear ntsia hlau stepping lub cev muaj zog yog tsim rau siab precision vim tias tsis muaj kev sib cuag ntawm cov khoom txav thiab qhov chaw ruaj khov vim qhov sib txawv ntawm qhov sib txawv thiab tsis hnav vim qhov kev kub ceev reciprocating txav ntawm cov movers. Lub pob ntsia hlau tsis tuaj yeem lav qhov tseeb ntawm qhov kev sib hloov ceev ceev, thiab kev sib txhuam ceev ceev yuav ua rau hnav cov ntsia hlau ntsia hlau, uas yuav cuam tshuam qhov tseeb ntawm cov lus tsa suab thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm qhov siab precision.
Kev xaiv ntawm sab nraud tsav linear lub cev muaj zog
Thaum ua linear motion txog cov khoom lossis cov kev daws teeb meem, peb xav kom engineers tsom rau cov ntsiab lus hauv qab no.
1. Dab tsi yog qhov load ntawm qhov system?
Lub load ntawm lub kaw lus muaj xws li cov load zoo li qub thiab dynamic load, thiab feem ntau qhov loj ntawm lub load txiav txim siab qhov loj me ntawm lub cev muaj zog.
Static load: qhov siab tshaj plaws thrust uas cov ntsia hlau tuaj yeem tiv taus thaum so.
Dynamic load: qhov siab tshaj plaws thrust uas cov ntsia hlau tuaj yeem tiv taus thaum nws txav mus.
2. Dab tsi yog linear khiav ceev ntawm lub cev muaj zog?
Kev khiav ceev ntawm lub cev muaj zog yog ze ze rau cov hlau lead ntawm cov ntsia hlau, ib lub kiv puag ncig ntawm cov ntsia hlau yog ib qho ntawm cov txiv ntoo. Rau kev ceev ceev, nws raug nquahu kom xaiv cov ntsia hlau nrog cov hlau lead me me, thiab rau kev kub ceev, nws raug nquahu kom xaiv cov ntsia hlau loj dua.
3. Dab tsi yog qhov yuav tsum tau muaj ntawm qhov system?
Screw raug: qhov tseeb ntawm cov ntsia hlau feem ntau yog ntsuas los ntawm qhov tseeb ntawm cov kab, piv txwv li qhov yuam kev ntawm qhov tseeb mus ncig thiab kev mus ncig theoretical tom qab cov ntsia hlau tig rau lub voj voog iab qhuav.
Rov ua qhov tseeb qhov tseeb: rov ua qhov tseeb qhov tseeb yog txhais tau tias yog qhov tseeb ntawm lub kaw lus kom ncav cuag txoj haujlwm tau hais ntau zaus, uas yog qhov taw qhia tseem ceeb rau lub kaw lus.
Backlash: backlash ntawm cov ntsia hlau thiab txiv ntseej ntawm so thaum ob lub axial txheeb ze txav tau. Raws li lub sij hawm ua hauj lwm nce, lub backlash kuj yuav nce vim hnav. Kev them nyiaj los yog kev kho ntawm backlash tuaj yeem ua tiav los ntawm kev tshem tawm cov txiv ntoo backlash. Thaum yuav tsum tau muab ob-directional positioning, backlash yog ib qho kev txhawj xeeb.
4. Lwm yam kev xaiv
Cov teeb meem hauv qab no kuj tseem yuav tsum tau txiav txim siab hauv cov txheej txheem xaiv: Puas yog lub mounting ntawm linear stepper lub cev muaj zog raws li kev tsim kho tshuab? Koj yuav txuas cov khoom txav mus rau lub txiv ntoo li cas? Dab tsi yog qhov zoo ntawm cov ntsia hlau ntsia hlau? Yuav ua li cas tsav yam twg?
