① Nyob ntawm seb hom kev txav mus los, qhov kev tsom xam yog txawv.Start-Stop kev ua haujlwm: Hauv hom kev ua haujlwm no, lub cev muaj zog txuas mus rau qhov load thiab ua haujlwm ntawm qhov ceev tsis tu ncua.Lub cev muaj zog yuav tsum ua kom lub nra hnyav (yuav kov yeej inertia thiab kev sib txhuam) nyob rau hauv thawj kauj ruam mus rau qhov ntau zaus.
Fais fab hom:Stepper lub cev muaj zogtsis pib
| Yog vim li cas | Kev daws teeb meem |
| Load yog siab dhau | Lub cev muaj zog yuam kev, xaiv lub cev muaj zog loj dua |
| zaus siab dhau lawm | Txo qhov xav tau |
| Yog hais tias lub cev muaj zog oscillates ntawm sab laug mus rau sab xis, ib theem yuav tawg los yog tsis txuas | Hloov lossis kho lub cev muaj zog |
| Phase tam sim no tsis tsim nyog | Nce theem tam sim no, tsawg kawg thaum thawj zaug ob peb kauj ruam. |
②Acceleration hom: Hauv qhov no, lubStepper lub cev muaj zogtso cai rau kom nrawm mus rau qhov siab tshaj plaws nrog rau kev nrawm nrawm preset hauv tus tsav tsheb.
Fais fab hom: Stepper lub cev muaj zog tsis pib
Yog vim li cas thiabkev daws teeb meemsaib ① ntu "Start-Stop operation".
Hom tsis ua haujlwm: Stepper lub cev muaj zog tsis ua tiav qhov nrawm nrawm.
| Yog vim li cas | Kev daws teeb meem |
| Lub cev muaj zog dai hauv resonance zaus | ● Ua kom nrawm nrawm mus dhau lub suab nrovzaus sai● Xaiv qhov pib-nres zaus tshaj qhov resonance point● Siv ib nrab-stepping lossis micro-stepping● Ntxiv ib lub tshuab damper uas tuaj yeem ua rau daim ntawvinertial disk ntawm rear ncej |
| Cov khoom siv hluav taws xob tsis raug lossis qhov chaw tam sim no (tsawg dhau) | ● Ua kom muaj hluav taws xob los yog tam sim no (nws raug tso cai los teeb tsa tus nqi siab duarau lub sijhawm luv luv)●Kuaj qis impedance lub cev muaj zog● Siv cov tsav tam sim no tsis tu ncua (yog tias siv lub zog hluav taws xob tas li) |
| Sab saum toj ceev heev | ● Txo qhov ceev tshaj plaws● Txo qhov nrawm nrawm |
| Tsis zoo ntawm lub acceleration ramp los ntawm lubelectronics (tshwm sim nrog digital ramps) | ● Sim nrog lwm tus tsav tsheb |
Hom tsis ua hauj lwm: Stepper lub cev muaj zog ua kom tiav acceleration tab sis stalls thaum mus txog qhov ceev.
| Yog vim li cas | Kev daws teeb meem |
| Stepper lub cev muaj zog ua haujlwm ntawm qhov txwv ntawm nws muaj peev xwm thiab stalls vim acceleration siab heev. Txoj hauj lwm equilibrium yog overshooted, ua rau rotor vibrations thiab instability. | ● Xaiv tus nqi qis dua lossis siv ob qhov sib txawvacceleration theem, siab thaum pib, qis rau sab saum toj ceev● Nce torque● Ntxiv ib lub tshuab damper rau ntawm lub nraub qaum. Nco ntsoov tiasqhov no yuav ntxiv rotor lub inertia thiab yuav tsis daws qhov teeb meemyog tias qhov siab tshaj plaws yog nyob ntawm qhov txwv ntawm lub cev muaj zog. ● Tsav lub cev muaj zog siv micro-stepping |
③ nce ntawm cov nyiaj them poob haujlwm dhau sijhawm
Qee zaum, lub cev muaj zog ua haujlwm ib txwm siv sijhawm ntev tab sis poob cov kauj ruam tom qab qee lub sijhawm. Nyob rau hauv tas li ntawd, nws yog zoo li hais tias lub load pom los ntawm lub cev muaj zog tau hloov. Nws tuaj yeem los ntawm kev hnav ntawm lub cev muaj zog bearings lossis los ntawm kev tshwm sim sab nraud.
Kev daws:
● Tshawb xyuas qhov muaj qhov tshwm sim sab nraud: Puas yog lub tshuab tsav los ntawm lub cev muaj zog hloov?
● Tshawb xyuas cov kabmob hnav: Siv cov kabmob pob kabmob es tsis txhob siv lub tes tsho sintered rau lub sijhawm ntev lub cev muaj zog.
● Tshawb xyuas seb qhov kub thiab txias puas tau hloov. Nws lub hwj chim ntawm cov kabmob lubricant viscosity tsis tseem ceeb rau micro motors. Siv cov roj nplua nyeem tsim nyog rau kev ua haujlwm ntau. (Piv txwv: lubricant tej zaum yuav nkig ntawm qhov kub thiab txias, lossis tom qab siv ntev, uas yuav ua rau kom them nyiaj ntau ntxiv)
