1,Ndezvipi zviratidzo zvemota zvine bipolar uye unipolar?
Mota dzeBipolar:
Mota dzedu dzeBipolar dzinowanzova nezvikamu zviviri chete, chikamu A nechikamu B, uye chikamu chimwe nechimwe chine waya mbiri dzinobuda, idzo dzinotenderera zvakasiyana. Hapana hukama pakati pezvikamu zviviri. Mota dzeBipolar dzine waya ina dzinobuda.
Mota dzeUnipolar:
Mota dzedu dzeUnipolar dzinowanzova nezvikamu zvina. Zvichibva pazvikamu zviviri zvemota dzeBipolar, mitsetse miviri yakafanana inowedzerwa.
Kana waya dzakabatana pamwe chete, waya dzinobuda dzine waya shanu.
Kana waya dzakajairika dzisina kubatana, waya dzinobuda dzine waya nhanhatu.
Mota imwe chete ine mitsetse mishanu kana mitanhatu inobuda.
2,Ndeipi frequency yepamusoro yekushandisa/frequency yepamusoro yekudhonza-kunze？
Kumhanya kwakanyanya / Kubuda kwakanyanya
Marefu ekumhanya, anozivikanwawo semarefu ekuslewing frequency / marefu ekudhonza-kunze, ndiyo marefu ekumhanya ayo mota inogona kuramba ichitenderera pasi peimwe fomu yekutyaira, voltage uye rated current, pasina kuwedzera mutoro.
Nekuda kwekusashanda zvakanaka kwerotor, mota inotenderera inoda torque shoma kuti itenderere zvichienzaniswa nemota isingachinji, saka kumhanya kwakawanda kuchave kwakakura kupfuura kumhanya kwakawanda kunotanga wega.
3,Chii chinonzi torque yekudhonza uye torque yekudhonza yemota yestepper?
Kudhonza-kunze torque
Torque yekudhonza ndiyo torque yepamusoro inogona kuendeswa pasina kurasikirwa nematanho. Inosvika pairi
padanho repamusoro kana kumhanya kwakaderera, uye kunoderera sezvo frequency ichiwedzera. Kana mutoro uri pa
mota yekukwira panguva yekutenderera inowedzera kupfuura torque yekudhonza, mota ichadonha padanho
uye kushanda nemazvo hakuzokwanisike.
Kudhonza-mukati torque
Torque yekudhonza ndiyo torque yepamusoro iyo mota inogona kutanga kutenderera pafrequency yakatarwa kubva
mamiriro asina kumira. Chitepisi hachigone kutanga kutenderera ne torque yemutoro inodarika torque yekudhonza.
Torque yekudhonza injini idiki pane torque yekudhonza injini, nekuda kwekusashanda zvakanaka kwerotor yemota.
4,Chii chinonzi torque ye stepper motor inozviisa panzvimbo yayo?
Detent torque itorque iripo mumamiriro asina simba nekuda kwekudyidzana kwesimba risingaperi
magineti nemazino e stator. Kukanganisika kunoonekwa kana kuvharika kwemota kunogona kunzwikwa nekutenderedza mota ne
ruoko. Kazhinji, mota yestepper icharasikirwa nekuenderana kana torque yekudhonza yadarika nekuda kwe
Mota dzinonyanya kudzorwa uye dzinoongororwa uchishandisa torque inodhonzwa pamusoro pe
zvinodiwa zvekushandisa kudzivirira kurasikirwa nekuverengwa kana nzvimbo dzemotokari.
5,Ndedzipi nzira dzekutyaira dzema stepper motors?
Kutyaira newave / one-phase-on kunoshanda nechikamu chimwe chete
inobatidzwa panguva imwe chete, inoratidzwa mumufananidzo uri kurudyi. Kana dhiraivha ichipa simba pole A (pole yekumaodzanyemba) inoratidzwa negirini, inokwezva pole yekuchamhembe yerotor. Ipapo kana dhiraivha ikaisa simba B uye ikadzima A, rotor inotenderera 90 ° uye izvi zvinoenderera mberi sezvo dhiraivha ichipa simba pole imwe neimwe panguva imwe chete.
Kutyaira kweMadanho maviri-maviri kune zita rayo nekuti madanho maviri anobatidzwa panguva imwe chete. Kana dhiraivha ichipa simba madanda ese A neB semadanho ekumaodzanyemba (anoratidzwa mugirini), ipapo danda rekuchamhembe rerotor rinokwevera kune ese ari maviri zvakaenzana uye rinobatidzwa pakati pemadanho maviri. Sezvo kutevedzana kwesimba kuchienderera mberi seizvi, rotor inoramba ichibatidzwa pakati pematanda maviri. Kutyaira kwematanho maviri-maviri hakuna kugadziriswa kwakanaka kupfuura rimwe-danho, asi kunogadzira torque yakawanda. Iyi ndiyo nzira yekutyaira yatinoshandisa kakawanda mumiedzo yedu, inozivikanwawo se "full step driving".
Kutyaira kwechikamu chimwe kusvika zviviri kunonzi 1-phase kunotumidzwa zita rekuti mutyairi anochinja pakati pechikamu chimwe kusvika zviviri zvekufadza. Mutyairi anopa simba padanda A, obva awedzera simba padanda A neB, obva awedzera simba padanda B, obva awedzera simba padanda A neB, zvichingodaro. (Zvinoratidzwa muchikamu chegirini kurudyi) Kutyaira kwechikamu chimwe kusvika zviviri kunopa simba rekufamba kwakaringana. Kana zvikamu zviviri zvawedzerwa simba, mota ine torque yakawanda. Heino chiyeuchidzo: Torque ripple inyaya, nekuti inogona kukonzera resonance uye vibration. Kana tichienzanisa nekutyaira kwechikamu chakazara/2-phase, step angle yekutyaira kwechikamu chimwe kusvika zviviri inongoderedzwa nehafu, uye zvinotora matanho maviri kutenderera kamwe chete, saka kutyaira kwechikamu chimwe kusvika zviviri kunonziwo "half step driving". Kutyaira kwechikamu chimwe kusvika zviviri kunogonawo kutariswa senzira inonyanya kupatsanurwa yekuderedza kupatsanurwa.
6，Ungasarudza sei mota yakakodzera yekukwira?
Kuti uwane sarudzo yakanakisisa, idzo
mitemo yedzidziso huru inofanira kuremekedzwa:
Basa rekutanga nderekusarudza mota yekukwira stepper yakakodzera yekushandisa.
1. Sarudza mota zvichibva pa torque/speed point yepamusoro inodiwa neapplication (sarudzo zvichibva pamhosva yakaipisisa)
2. Shandisa margin yedhizaini inosvika 30% kubva pa torque yakaburitswa vs. speed curve (pull-out curve).
3. Iva nechokwadi chekuti application haizodziviswi nezviitiko zvekunze.
