Txoj cai ua haujlwm thiab qhov zoo ntawm NEMA stepping motor tuaj yeem nkag siab sai sai

1 Dab tsi yog ib qhoNEMAlub cev muaj zog stepper?

Stepping motor yog ib hom digital control motor, uas yog siv dav hauv ntau yam khoom siv tsis siv neeg. LubNEMA lub cev muaj zog kauj ruamyog lub cev muaj zog stepping uas tsim los ntawm kev sib txuas cov txiaj ntsig ntawm hom hlau nplaum tas mus li thiab hom reactive. Nws cov qauv zoo ib yam li lub cev muaj zog stepping. Lub rotor muab faib ua ob ntu hauv qhov kev taw qhia axial. Ob ntu ntawm cov hlau tub ntxhais tau faib sib npaug zos nrog tib tus lej thiab qhov loj ntawm cov hniav me me hauv qhov kev taw qhia circumferential, tab sis lawv tau staggered los ntawm ib nrab ntawm cov hniav pitch.

2 Txoj cai ua haujlwm ntawmNEMAlub cev muaj zog kauj ruam

Cov qauv ntawm NEMA stepping motor zoo ib yam li cov qauv ntawm reluctance motor, uas kuj muaj stator thiab rotor. Lub stator feem ntau muaj 8 ncej lossis 4 ncej. Muaj qee tus lej ntawm cov hniav me me tau faib sib npaug ntawm qhov chaw ntawm tus ncej. Lub kauj ntawm tus ncej tuaj yeem muaj zog hauv ob qho kev taw qhia los tsim theem a thiab theem a, thiab theem b thiab theem b.

Txhua cov hniav ntawm tib ntu ntawm cov hniav rotor muaj tib lub polarity, thaum lub polarity ntawm ob lub hniav rotor hauv ntau ntu yog qhov sib txawv. Qhov sib txawv loj tshaj plaws ntawm NEMA stepping motor thiab reactive stepping motor yog tias thaum cov khoom siv magnetized tas mus li raug demagnetized, yuav muaj cov ntsiab lus oscillation thiab tawm ntawm cov kauj ruam.

 

3 Qhov Zoo ntawmNEMAlub cev muaj zog kauj ruam

Lub rotor ntawm NEMA stepping motor yog magnetic, yog li lub torque tsim nyob rau hauv tib lub stator tam sim no yog loj dua li ntawm reactive stepping motor, thiab lub kaum sab xis feem ntau me me. Tib lub sijhawm, nrog rau kev nce ntawm tus lej ntawm cov theem (tus lej ntawm cov energized windings), lub kaum sab xis ntawm NEMA stepping motor txo qis thiab qhov tseeb tau txhim kho. Hom stepping motor no yog siv dav tshaj plaws.

 

Cov txiaj ntsig ntawmNEMAkauj ruam tsav tsheb:

1. Thaum tus naj npawb ntawm cov khub ncej sib npaug rau tus naj npawb ntawm cov hniav rotor, nws qhov kev hloov pauv tuaj yeem hloov kho raws li qhov xav tau;

2. Qhov winding inductance hloov me ntsis nrog rau txoj haujlwm rotor, uas ua rau nws yooj yim kom ua tiav kev tswj hwm kev ua haujlwm zoo tshaj plaws;

3. Thaum siv cov khoom siv sib nqus tshiab uas muaj zog sib nqus siab hauv lub voj voog sib nqus axial, kev ua haujlwm ntawm lub cev muaj zog tuaj yeem txhim kho;

4. Lub rotor tuaj yeem muab kev txhawb zog rau cov hlau nplaum.
