Qhov txawv ntawm AC Servo Tsav thiab Stepper tsav
Nws yog zoo paub tias lub luag hauj lwm tseem ceeb ntawm lub cav yog los tsim cov neeg tsav tsheb khiav, raws li lub hwj chim los ntawm ntau yam ntawm cov hluav taws xob thiab mechanical operation, yog ib qho tseem ceeb ntawm CNC kev siv tshuab, butthere yog ob hom kev tsav tsheb yog dav siv nyob rau hauv lub tam sim no ua lag luam
, ib tug stepping Tsav, qhov tod yog AC servo tsav, nram qab no peb muaj ib tug closer saib qhov txawv nruab nrab ntawm ob lub cev kev ua haujlwm
Stepper lub cev yog ib lub tshuab lim yooj yim, nws thiab niaj hnub tswj digital technology muaj qhov sib txuas tseem ceeb. Nyob rau hauv qhov kev tswj hwm ntawm kev tswj cov kev tswj hwm tam sim no , daim ntawv thov ntawm stepper lub cev muaj zog heev.Thiab qhov kev tawm ntawm tag nrho cov digital AC servo systems, AC servo motors kuj nce siab siv hauv cov kev tswj digital.Thaum kom tau raws li txoj kev loj hlob ntawm cov tswj, feem ntau ntawm cov lus tsa suab tswj lawv siv cov stepper tsav lossis tag nrho cov digital AC servo tsav ua lub cav tsav.Txawm tias ob leeg yog cov zoo sib xws ntawm kev tswj hom ( pulse series thiab cov teebmeem kev taw qhia), muaj ntau qhov sib txawv hauv kev ua tau zoo thiab daim ntawv thov.Tam sim no qhov kev ua tau zoo ntawm ob.
Ua ntej, kev tswj raug yog txawv
Ob-theem hybrid stepper tsav lub kaum sab xis yog feem ntau 3.6 °, 1.8 ° thiab 1.2 °, tsib-theem hybrid stepper tsav lub kaum sab xis yog feem ntau
0.72 °, 0.36 ° .Nws tseem muaj qee qhov kev ua tau zoo tshaj theem stepper motors nrog cov kauj ruam me me me dua.Thiab li plaub-txoj kev lag luam
rau kev siv EDM tshuab stepper tsav, lub kaum sab xis yog 0.09 °; Lub teb chaws Yelemees BERGER LAHR lag luam ntawm peb theem
hybrid stepper tsav, nws cov kauj ruam kaum ntawm DIP hloov tau teem rau 1.8 °, 0.9 °, 0.72 °, 0.36 °, 0.18 °, 0.09 °, 0.072 °, 0.036 °, tau tshaj ob theem thiab tsib theem zuj zus stepper tsav Step angle.Shenzhen ECON Technology nquag ua bipolar thiab peb theem stepping lub cev, thiab cov kaum sab xis yog 1.8 °, 1.2 °, yuav siv tau rau hauv cov tshuab CNC feem ntau.
Qhov tseeb ntawm AC servo lub cev yog guaranteed los ntawm lub teb chaws tuaj sab nraub qaum ntawm lub cav tsav tsheb.Hub ECON tag nrho cov digital AC servo tsav piv txwv, nrog ib tug qauv 2500-hlau encoder tsav, vim tsav tsheb siv ntawm kev siv tshuab quadruple frequency , qhov sib npaug ntawm 360 ° / 10000 = 0.036 °. Rau kev tsav tsheb nrog 17-ntsis encoders, tus tsav tsheb tau txais 217 = 131072 mem tes, motors tig ib puag ncig, piv txwv li, qhov sib npaug yog 360 ° / 131072 = 9.89 vib nas this, yog 1 / 655 ntawm qhov mem tes sib npaug ntawm lub cav xaib nrog theem kaum sab xis 1.8 °.
Thib ob, yam ntxwv sib txawv tsawg
Stepper tsav yog yooj yim kom muaj tsawg zaus kev co phenomenon ntawm tsawg ceev.Qhov kev nquag muaj feem xyuam nrog rau load
mob thiab tsav kev tsav.Nws feem ntau ntseeg tau hais tias qhov kev ua kom muaj zog yog ib nrab ntawm kev tsav tsheb tsis-thauj -tawm zaus.Qhov no muaj tsawg zaus kev co phenomenon, uas yog txiav txim siab los ntawm txoj cai ua haujlwm ntawm kev ua theem pib , yog qhov tsis zoo rau qhov kev khiav haujlwm ntawm lub tshuab. Thaum cov nqes hlau cav khiav hauj lwm thaum qis qis, kev thev naus laus zis yuav tsum tau siv los ua kom tsis muaj teeb meem tsawg zaus, xws li ntxiv lub zog ntawm lub tshuab tsav los yog siv cov tshuab siv micro-step.
AC servo lub cev khiav zoo heev, txawm tias thaum qis qeeb tsis tshwm sim los ntawm kev ua kom muaj teeb meem ntawm kev ua haujlwm resomance, muaj peev xwm them rau cov tsis muaj kev sib raug zoo, thiab muaj lub nrog sab hauv muaj qhov kev daws teeb meem (FFT), tuaj yeem txheeb xyuas cov neeg ua hauj lwm resonance taw tes, yooj yim los kho qhov system.
Qeb peb, cov yam ntxwv txawv torque-zaus
Lub qhov tso zis torque ntawm lub cav qis dua zuj zus raws li qhov ceev nce thiab txo qis ntawm qis dua, yog li qhov siab tshaj plaws khiav ceev feem ntau ntawm 300 thiab 600 RPM.AC servo tsav yog qhov kev tso zis torque, uas yog, hauv nws cov nqi ceev (feem ntau yog 2000RPM los yog 3000RPM), tuaj yeem tso tawm cov teeb tau los ntawm qhov siab, qhov siab ceev yog qhov tso zis hluav taws xob.
Qeb plaub, muaj peev xwm ntau dua
Stepper motors feem ntau tsis muaj peev xwm ntau dua.AC servo motor muaj lub zog muaj peev xwm ntau dua.Haus ECON AC servo
qhov ua piv txwv, nws muaj kev ceev tshaj thiab muaj peev xwm ntau zog dua.Thaum lub siab tshaj plaws torque yog peb lub sij hawm ntawm cov tswv yim taw kev thiab siv tau los kov yeej inertia torque ntawm lub caij nplooj ntoos hlav thaum pib ntawm kev ua kom tiav.Stepping motor txij li tsis muaj xws li muaj peev xwm hla dhau qhov muaj peev xwm, kom thiaj li kov tau qhov kev xav ntawm no, feem ntau yuav tsum tau xaiv ib lub zog loj ntawm lub tshuab, thaum lub tshuab tsis xav tau qhov kev lag luam loj thaum ua hauj lwm, ces pov tseg ntawm torque.
Thib tsib, qhov sib tw khiav yog txawv
Stepper motor tswj yog qhib kev sib tsoo, qhov pib zaus loj dhau los yog lub nra hnyav loj rau cov kauj ruam poob los yog qhov teeb meem, nres ntawm kev kub ceev yog nquag saib xyuas qhov teeb meem, yog li kom nws txoj kev tswj hwm, thiab txo qhov teeb meem ceev ceev.AC servo tsav yog kaw-voj tswj, tus neeg tsav tsheb yuav tsum ncaj qha los ntawm lub cev muaj peev xwm ntawm cov teeb meem kev tawm tswv yim, qhov txheej txheem ntawm lub voj qhov chaw thiab kev voj voj, feem ntau tsis tshwm stepping motor ruam poob los yog overshoot phenomenon , tswj kev ua tau zoo dua.
Rau, qhov kev ua teb rau kev ua teb ceev yog txawv
Nqus cav los ntawm kev ceev nrawm rau kev ua hauj lwm ceev (feem ntau pua pua kev lem ib feeb) yuav tsum muaj 200 mus rau 400
milliseconds.AC servo system acceleration kev ua tau zoo dua, siv ECON 400W AC servo lub cev piv txwv, los ntawm kev ceev nruj rau nws cov nqi ceev 3000RPM xwb ob peb milliseconds, siv tau rau kev pib yoojyim thiab tswj kev tiv thaiv .
Hauv kev xaus, lub AC servo system yog superior rau stepper motors rau ntau yam kev ua tau zoo dua.Tab sis, nyob hauv qee qhov yuav tsum ua kom tsawg
feem ntau siv stepper lub cev kom ua lub cav ua kom tiav.Yog li no, ECON nco ntsoov tias cov neeg tau txais kev pabcuam hauv kev yuav tsav tsheb tswj cov txheej txheem yuav tsum xav txog kev tswj cov kev cai, cov nqi thiab lwm yam, xaiv lub tswj kev tsav.
