1,Dab tsi yog bipolar thiab unipolar yam ntxwv ntawm lub cev muaj zog?
Bipolar Motors:
Peb cov motors bipolar feem ntau tsuas muaj ob theem, theem A thiab theem B, thiab txhua theem muaj ob lub xov hlau tawm, uas yog nyias nyias. Tsis muaj kev sib txuas ntawm ob theem. Bipolar motors muaj 4 cov xaim tawm.
Unipolar motors:
Peb unipolar motors feem ntau muaj plaub theem. Raws li ob theem ntawm bipolar motors, ob kab ntau ntxiv.
Yog tias cov xov hlau sib txuas txuas ua ke, cov xaim tawm yog 5 xov hlau.
Yog tias cov xov hlau tsis sib txuas ua ke, cov xaim tawm yog 6 xov hlau.
Lub cev muaj zog unipolar muaj 5 lossis 6 kab tawm.
2,Dab tsi yog qhov ua haujlwm siab tshaj plaws / qhov siab tshaj plaws rub tawm zaus?
Maximum khiav ntau zaus / siab tshaj rub tawm zaus
Qhov siab tshaj plaws khiav ntau zaus, tseem hu ua qhov siab tshaj plaws slewing zaus / qhov siab tshaj plaws rub tawm zaus, yog qhov siab tshaj plaws uas lub cev muaj zog tuaj yeem ua kom tig raws li ib qho kev tsav tsheb, qhov hluav taws xob thiab ntsuas tam sim no, tsis tas yuav ntxiv lub load.
Vim lub inertia ntawm lub rotor, lub rotating lub cev muaj zog yuav tsum tau tsawg torque rau spin piv rau ib tug nyob ruaj ruaj lub cev muaj zog, yog li qhov siab tshaj plaws khiav zaus yuav loj dua qhov siab tshaj plaws nws tus kheej pib zaus.
3,Dab tsi yog qhov rub torque thiab rub lub zog ntawm lub tshuab stepper?
Tshem tawm torque
Pull-out torque yog qhov siab tshaj plaws torque uas tuaj yeem xa tawm yam tsis poob cov kauj ruam. Nws ncav cuag nws
qhov siab tshaj plaws ntawm qhov tsawg tshaj plaws los yog ceev, thiab txo qis raws li qhov zaus nce. Yog hais tias lub load ntawm lub
stepping lub cev muaj zog thaum lub sij hawm tig tsub kom dhau lub rub tawm torque, lub cev muaj zog yuav poob ntawm kauj ruam
thiab kev ua haujlwm raug yuav ua tsis tau.
Pull-in torque
Pull-in torque yog qhov siab tshaj plaws torque uas lub cev muaj zog tuaj yeem pib tig ntawm ib qho zaus los ntawm
nyob ruaj khov. Lub stepper tsis tuaj yeem pib tig nrog lub load torque tshaj qhov rub-hauv torque.
Pull-in torque yog me dua li rub tawm torque, vim yog inertia ntawm lub cev muaj zog lub rotor.
4,Dab tsi yog qhov nws tus kheej positioning torque ntawm stepper lub cev muaj zog?
Detent torque yog lub zog torque tam sim no nyob rau hauv lub xeev unenergized vim muaj kev cuam tshuam ntawm qhov ruaj khov
hlau nplaum thiab stator hniav. Qhov pom kev cuam tshuam los yog cogging tuaj yeem hnov los ntawm kev tig lub cev muaj zog los ntawm
tes.Feem ntau, lub stepper lub cev muaj zog yuav plam synchronization thaum lub rub tawm torque yog tshaj vim
overload. Motors feem ntau xaiv thiab ntsuas siv rub tawm qhov tseem ceeb ntawm lub zog saum toj no
cov kev cai rau daim ntawv thov los tiv thaiv kev suav ploj lossis lub khw muag khoom.
5,Dab tsi yog qhov kev tsav tsheb ntawm stepper motors?
Wave / one-phase-on tsav tsheb ua haujlwm nrog tsuas yog ib theem
tig rau ntawm ib lub sij hawm, qhia nyob rau hauv lub illustration sab xis. Thaum tus tsav energizes ncej A (sab qab teb ncej) qhia nyob rau hauv ntsuab, nws attracts sab qaum teb ncej ntawm lub rotor. Tom qab ntawd thaum lub driveenergizes B thiab hloov A tawm, lub rotor tig 90 ° thiab qhov no txuas ntxiv mus raws li tus tsav energizes txhua tus ncej ib zaug.
2-2 Phase Tsav Tsheb muaj nws lub npe vim tias ob theem nyob rau ib zaug. Yog hais tias tus tsav energizes ob A thiab B ncej raws li sab qab teb ncej (pom ntsuab), ces lub rotor sab qaum teb ncej attracts rau ob qho tib si sib npaug thiab aligns nyob rau hauv nruab nrab ntawm ob. Raws li lub zog ua ntu zus txuas ntxiv mus zoo li qhov no, lub rotor tsis tu ncua xaus rau hauv-nruab nrab ntawm ob tug ncej. 2-2 theem tsav tsheb tsis muaj kev daws teeb meem zoo dua li ib-theem ntawm, tab sis nws tsim ntau lub zog. Qhov no yog txoj kev tsav tsheb uas peb siv feem ntau hauv peb qhov kev xeem, tseem hu ua "kev tsav tsheb tag nrho".
1-2 theem tsav tsheb muaj npe tom qab tus neeg tsav tsheb hloov ntawm 1-theem thiab 2-theem ntawm excitation. Tus neeg tsav tsheb energizes ncej A, ces energizes ob tug ncej A thiab B, ces energizes ncej B, ces energizes ob tug ncej A thiab B, thiab lwm yam. (Qhia rau ntawm qhov ntsuab nyob rau sab xis) 1-2 theem tsav tsheb muab kev daws teeb meem zoo dua. Thaum 2 theem muaj zog, lub cev muaj zog muaj zog ntau dua. Nov yog ib qho kev ceeb toom: Torque ripple yog ib qho kev txhawj xeeb, vim nws yuav ua rau resonance thiab vibration. Piv nrog rau kev tsav tsheb tag nrho / 2-2-theem tsav tsheb, lub kaum sab xis ntawm 1-2-theem tsav tsuas yog ib nrab, thiab nws yuav siv ob zaug ntawm cov kauj ruam los tig ib lub kiv puag ncig, yog li 1-2 theem kev tsav tsheb kuj tseem hu ua "ib nrab kauj ruam tsav" 1-2 theem tsav kuj tseem tuaj yeem suav tias yog qhov tseem ceeb tshaj plaws kev tsav tsheb.
6,Yuav ua li cas xaiv ib tug haum stepper lub cev muaj zog?
Rau qhov kev xaiv zoo tshaj plaws, cov
Cov kev cai theoretical tseem ceeb yuav tsum raug hwm:
Thawj txoj haujlwm yog xaiv txoj cai stepper lub cev muaj zog rau daim ntawv thov.
1. Xaiv lub cev muaj zog raws li qhov siab tshaj plaws torque / ceev taw tes yuav tsum tau los ntawm daim ntawv thov (xaiv raws li qhov phem tshaj)
2. Siv tsawg kawg yog 30% tus qauv tsim los ntawm kev tshaj tawm torque vs. ceev nkhaus (rub-tawm nkhaus).
3. Xyuas kom meej tias daim ntawv thov yuav tsis raug kaw los ntawm cov xwm txheej sab nraud.
