Yuav ua li cas yog lub stepper lub cev muaj zog qauv?

Stepper lub cev muaj zog qauv muaj 4 qhov chaw, uas sawv cev rau tus ncej naj npawb, lub cev muaj zog hom (BYF sawv cev rau hybrid hom, BC sawv cev rau reactive hom), tus naj npawb ntawm cov theem, thiab tus naj npawb ntawm lub cev muaj zog rotor hniav.

1. Tus naj npawb: tseem hu ua lub cev muaj zog sab nraud, muaj 28, 42, 57, 86, 110, thiab 130 qauv.

2. Hom lub cev muaj zog
Reactive hom: Muaj windings ntawm stator thiab rotor yog ua los ntawm cov khoom sib nqus mos. Nws muaj cov qauv yooj yim, tus nqi qis, lub kaum sab xis me me, mus txog 1.2 degree, tab sis kev ua haujlwm tsis zoo, kev ua haujlwm qis, kev tsim hluav taws xob siab, thiab kev ntseeg tau nyuaj.

Hom hlau nplaum tas mus li: Lub rotor ntawm cov hlau nplaum ruaj khov stepper lub cev muaj zog yog ua los ntawm cov khoom siv hlau nplaum ruaj khov, thiab tus naj npawb ntawm cov rotor ncej yog tib yam li cov stator ncej. Nws yog tus cwj pwm los ntawm kev ua tau zoo ntawm kev ua haujlwm zoo thiab cov khoom tso tawm loj, tab sis lub cev muaj zog muaj qhov tsis zoo thiab lub kaum sab xis loj (feem ntau 7.5 degree lossis 15 degree).

Hybrid: Lub hybrid stepper lub cev muaj zog ua ke nrog qhov zoo ntawm cov hlau nplaum reactive thiab ruaj khov. Nws muaj ntau theem windings ntawm stator, cov khoom siv hlau nplaum ruaj khov ntawm lub rotor, thiab ntau cov hniav me me ntawm lub rotor thiab stator los txhim kho cov kauj ruam raug. Nws cov yam ntxwv yog cov zis loj torque, zoo dynamic kev ua tau zoo, thiab cov kauj ruam me me, tab sis cov qauv yog complex thiab tus nqi kuj siab.

3. Tus naj npawb ntawm theem: tus naj npawb ntawm excitation coils uas tsim cov polar N thiab S sib nqus teb. Nws feem ntau yog sawv cev los ntawm m.

4. Tus naj npawb ntawm cov hniav rotor

Tus naj npawb ntawm cov hniav rotor yog tus naj npawb ntawm cov hniav rotor ntawm cov ntsiab lus rotor. Qhov sib txawv ntawm tus naj npawb ntawm cov hniav rotor yuav hloov qhov sib ntxiv ntawm ib theem coils; Hloov cov polarity ntawm cov hlau nplaum sib nqus ntawm lub kauj, cuam tshuam rau cov khoom sib nqus ntawm cov hlau nplaum ntawm ib theem kauj, thiab tom qab ntawd cuam tshuam cov yam ntxwv ntawm lub cev muaj zog, thiab tseem cuam tshuam rau lub zog ceev ntawm lub cev muaj zog.

Stepper motors yog tsim los ntawm peb lub ntsiab lus tseem ceeb: lub kaum sab xis (nrog rau tus lej ntawm cov theem), static torque, thiab tam sim no. Thaum peb lub ntsiab lus tseem ceeb tau txiav txim siab, tus qauv ntawm lub tshuab stepper tau txiav txim siab.

1. Kauj ruam xaiv

Lub kaum sab xis ntawm lub cev muaj zog nyob ntawm qhov yuav tsum tau ua kom raug. Qhov tsawg kawg nkaus daws teeb meem (sib npaug) ntawm lub load yog hloov mus rau lub cev muaj zog ncej. Muaj pes tsawg lub ces kaum yuav tsum txhua qhov sib npaug ntawm lub cev muaj zog txav (nrog rau kev deceleration). Lub kaum sab xis ntawm lub cav yuav tsum sib npaug los yog tsawg dua lub kaum sab xis no.

2. Static torque xaiv

Lub hauv paus rau static torque xaiv yog lub load ntawm lub cev muaj zog, thiab lub load yuav muab faib ua ob hom: inertial load thiab kev sib txhuam load. Ib qho inertial load thiab ib qho kev sib txhuam load tsis muaj nyob. Thaum pib ncaj qha (feem ntau ntawm qhov ceev ceev), ob qho tib si loads yuav tsum tau txiav txim siab. Thaum accelerating pib, lub inertial load feem ntau yog xam. Thaum khiav ntawm qhov ceev tsis tu ncua, tsuas yog kev sib txhuam load yuav tsum tau xav txog.

3. Kev xaiv tam sim no

Motors nrog tib lub zog zoo li qub muaj qhov sib txawv ntawm kev ua haujlwm vim muaj qhov sib txawv tam sim no. Tam sim no ntawm lub cev muaj zog tuaj yeem raug txiav txim raws li qhov torque-frequency tus yam ntxwv nkhaus.
