Lub cev muaj zog steppertxoj cai ua haujlwm
Feem ntau, lub rotor ntawm lub cev muaj zog yog lub hlau nplaum tas mus li. Thaum tam sim no ntws los ntawm stator winding, lub stator winding tsim ib lub vector magnetic field. Lub magnetic field no tsav lub rotor kom tig los ntawm ib lub kaum sab xis kom qhov kev taw qhia ntawm lub rotor ob lub magnetic fields sib xws nrog lub stator lub teb. Thaum lub vector magnetic field ntawm stator tig los ntawm ib lub kaum sab xis.
Lub cev muaj zog stepperyog ib hom induction motor, nws txoj haujlwm ua haujlwm yog siv hluav taws xob Circuit Court, qhov tam sim no ncaj qha mus rau hauv lub sijhawm sib koom fais fab mov, multiphase timing tswj tam sim no, nrog rau qhov tam sim no rau stepper lub cev muaj zog fais fab mov, stepper lub cev muaj zog tuaj yeem ua haujlwm kom zoo, tus tsav tsheb yog rau stepper lub cev muaj zog sib koom fais fab mov, multiphase timing controller.
Txhua zaus uas muaj hluav taws xob nkag los, lub cev muaj zog yuav tig ib lub kaum sab xis mus tom ntej ib kauj ruam. Qhov kev hloov pauv ntawm lub kaum sab xis ntawm cov zis yog sib npaug rau cov zaus ntawm cov pulses nkag, thiab qhov ceev yog sib npaug rau qhov zaus ntawm cov pulse. Yog li ntawd, koj tuaj yeem tswj tau tus naj npawb ntawm cov pulses, zaus thiab qhov kev txiav txim ntawm kev siv hluav taws xob txhua theem ntawm lub cev muaj zog winding los tswj kev tig ntawm lub cev muaj zog stepper.
Qhov tseeb ntawm lub cev muaj zog stepper dav dav yog 3-5% ntawm lub kaum sab xis, thiab nws tsis sib sau ua ke.
Lub zog ntawm lub cev muaj zog stepper yuav txo qis thaum qhov ceev nce ntxiv. Thaum lub cev muaj zog stepper tig, qhov inductance ntawm txhua theem ntawm lub cev muaj zog winding yuav tsim lub zog hluav taws xob rov qab; qhov siab dua qhov zaus, qhov ntau dua qhov rov qab hluav taws xob. Hauv qab nws qhov kev ua, lub cev muaj zog nrog qhov zaus (lossis qhov ceev) nce thiab qhov tam sim no theem txo qis, uas ua rau lub zog txo qis.
Lub cev muaj zog stepper tuaj yeem ua haujlwm li qub ntawm qhov ceev qis, tab sis yog tias siab dua qee qhov ceev nws yuav tsis pib, thiab nrog lub suab whistling.
Lub cev muaj zog stepper muaj ib qho kev ntsuas: qhov zaus pib tsis muaj load, uas yog, lub cev muaj zog stepper hauv qhov xwm txheej ntawm qhov zaus pulse tsis muaj load tuaj yeem pib tau ib txwm, yog tias qhov zaus pulse siab dua tus nqi, lub cev muaj zog tsis tuaj yeem pib ib txwm, tej zaum yuav tshwm sim tawm ntawm kauj ruam lossis thaiv.
Yog tias muaj kev thauj khoom, qhov pib zaus yuav tsum qis dua. Yog tias lub cev muaj zog yuav tsum ua tiav kev sib hloov ceev ceev, qhov zaus ntawm lub zog yuav tsum muaj cov txheej txheem ua kom nrawm dua, piv txwv li, qhov pib zaus qis dua, thiab tom qab ntawd nce mus rau qhov zaus siab xav tau (qhov ceev ntawm lub cev muaj zog los ntawm qhov ceev qis mus rau qhov ceev siab) ntawm qee qhov kev nrawm.
Vim li cas thiaj uacov cav stepperyuav tsum tau tswj hwm nrog kev txo qis ceev
Qhov ceev ntawm lub cev muaj zog stepper nyob ntawm qhov zaus ntawm lub zog pulse, tus naj npawb ntawm cov hniav rotor thiab tus naj npawb ntawm cov beats. Nws qhov ceev angular yog proportional rau qhov zaus ntawm lub zog pulse thiab yog synchronized hauv lub sijhawm nrog lub zog pulse. Yog li, yog tias tus naj npawb ntawm cov hniav rotor thiab tus naj npawb ntawm cov khiav beats yog qhov tseeb, qhov ceev xav tau tuaj yeem tau txais los ntawm kev tswj hwm qhov zaus ntawm lub zog pulse. Txij li thaum lub cev muaj zog stepper tau pib nrog kev pab los ntawm nws lub zog synchronous, qhov zaus pib tsis siab kom tsis txhob poob kauj ruam. Tshwj xeeb tshaj yog thaum lub zog nce, lub rotor txoj kab uas hla nce, qhov inertia nce, thiab qhov zaus pib thiab qhov zaus khiav siab tshaj plaws yuav txawv ntawm kaum npaug.
Cov yam ntxwv ntawm lub cev muaj zog stepper pib zaus kom lub cev muaj zog stepper pib tsis tuaj yeem ncaj qha mus txog qhov zaus ua haujlwm, tab sis kom muaj cov txheej txheem pib, uas yog, los ntawm qhov ceev qis maj mam nce mus rau qhov ceev ua haujlwm. Nres thaum qhov zaus ua haujlwm tsis tuaj yeem poob rau xoom tam sim ntawd, tab sis kom muaj qhov ceev ceev maj mam txo qis rau xoom.
Yog li ntawd, feem ntau, kev ua haujlwm ntawm lub cev muaj zog stepper yuav tsum dhau los ntawm kev nrawm, kev ceev sib xws, kev qeeb qeeb peb theem, kev nrawm thiab kev qeeb qeeb kom luv li sai tau, lub sijhawm ceev tas li ntev li ntev tau. Tshwj xeeb tshaj yog nyob rau hauv txoj haujlwm uas xav tau kev teb sai, lub sijhawm yuav tsum khiav ntawm qhov pib mus rau qhov kawg yog qhov luv tshaj plaws, uas yuav tsum tau ua kom luv tshaj plaws ntawm kev nrawm thiab kev qeeb qeeb, thiab qhov ceev tshaj plaws ntawm qhov ceev tas li.
Cov txheej txheem kev nrawm thiab qeeb yog ib qho ntawm cov thev naus laus zis tseem ceeb hauv kev tswj kev txav mus los, thiab yog ib qho tseem ceeb uas ua rau muaj kev ceev ceev thiab ua haujlwm tau zoo. Hauv kev tswj hwm kev lag luam, ntawm ib sab tes, cov txheej txheem ntawm kev ua haujlwm yuav tsum du thiab ruaj khov, nrog rau qhov cuam tshuam me me ntawm kev ywj pheej; ntawm qhov tod tes, nws xav tau lub sijhawm teb sai thiab kev teb sai. Hauv lub hauv paus ntawm kev ua kom muaj kev tswj hwm kom zoo dua qub, kom ua tiav kev txav mus los du thiab ruaj khov, yog qhov kev ua haujlwm hauv kev lag luam tam sim no tau daws qhov teeb meem tseem ceeb. Cov txheej txheem kev nrawm thiab qeeb uas feem ntau siv hauv cov txheej txheem tswj kev txav mus los tam sim no suav nrog: kev nrawm thiab qeeb ntawm cov nkhaus trapezoidal, kev nrawm thiab qeeb ntawm cov nkhaus exponential, kev nrawm thiab qeeb ntawm cov nkhaus S-zoo li, kev nrawm thiab qeeb ntawm cov nkhaus parabolic, thiab lwm yam.
Kev nrawm thiab kev qeeb ntawm cov kab Trapezoidal
Kev Txhais: Kev nrawm/kev qeeb qeeb hauv ib txoj kab ncaj (kev nrawm/kev qeeb qeeb los ntawm qhov pib ceev mus rau qhov ceev uas xav tau) nrog rau qee qhov piv
Cov qauv xam: v(t)=Vo+at
Qhov Zoo thiab Qhov Tsis Zoo: Cov kab Trapezoidal yog tus cwj pwm los ntawm cov algorithm yooj yim, siv sijhawm tsawg dua, teb sai, ua haujlwm tau zoo thiab yooj yim siv. Txawm li cas los xij, cov theem kev nrawm thiab kev qeeb tsis sib xws tsis ua raws li txoj cai hloov pauv ceev ntawm stepper motor, thiab qhov chaw hloov pauv ntawm qhov ceev hloov pauv thiab qhov ceev sib xws tsis tuaj yeem du. Yog li ntawd, cov algorithm no feem ntau yog siv rau hauv cov ntawv thov uas qhov yuav tsum tau ua rau cov txheej txheem kev nrawm thiab kev qeeb tsis siab.
Kev nrawm thiab kev qeeb ntawm cov kab exponential
Kev Txhais: Nws txhais tau tias kev ua kom nrawm thiab kev qeeb los ntawm kev ua haujlwm exponential.
Kev ntsuas kev tswj hwm kev nrawm thiab kev qeeb:
1, Kev khiav ntawm lub tshuab thiab qhov yuam kev ntawm txoj haujlwm yuav tsum me me li sai tau
2, Cov txheej txheem txav ntawm lub tshuab yog du, jitter me me, thiab cov lus teb yog ceev
3, kev ua kom nrawm thiab qeeb algorithm yuav tsum yooj yim li sai tau, yooj yim rau kev siv, thiab tuaj yeem ua tau raws li qhov xav tau kev tswj hwm tiag tiag
