Cov yam ntxwv ntawm Stepper Motors

01

Txawm hais tias rau tib lub cev muaj zog stepper, lub sijhawm zaus tus yam ntxwv sib txawv heev thaum siv cov txheej txheem tsav sib txawv.

2

Thaum lub stepping lub cev muaj zog nyob rau hauv lub lag luam, lub mem tes signals yog ntxiv rau windings ntawm txhua theem nyob rau hauv lem nyob rau hauv ib tug tej yam kev txiav txim (nyob rau hauv ib txoj kev uas lub windings yog energized thiab de-energised los ntawm lub nplhaib distributor nyob rau hauv tus neeg tsav tsheb).

3

Stepping lub cev muaj zog yog txawv los ntawm lwm cov motors, nws nominal rated voltage thiab rated tam sim no tsuas yog siv qhov tseem ceeb; thiab vim hais tias lub stepping lub cev muaj zog yog powered los ntawm pulses, lub hwj chim mov voltage yog nws siab tshaj voltage, tsis yog qhov nruab nrab voltage, yog li ntawd lub stepping lub cev muaj zog yuav ua hauj lwm tshaj nws rated range. Tab sis kev xaiv yuav tsum tsis txhob deviate deb dhau ntawm tus nqi ntsuas.

Stepping lub cev muaj zog tsis muaj qhov yuam kev ntau: feem ntau qhov tseeb ntawm stepping lub cev muaj zog yog peb mus rau tsib feem pua ​​​​ntawm cov kauj ruam tiag tiag, thiab nws tsis tau sau.

Qhov siab tshaj plaws uas tso cai rau lub cev muaj zog: qhov kub siab ntawm lub cev muaj zog yuav ua ntej demagnetise cov khoom sib nqus ntawm lub cev muaj zog, uas yuav ua rau lub zog poob lossis txawm tias tawm ntawm kauj ruam, yog li qhov siab tshaj plaws tso cai ntawm lub cev muaj zog yuav tsum nyob ntawm qhov demagnetisation point ntawm cov khoom sib nqus ntawm cov motors sib txawv; Feem ntau, qhov demagnetisation point ntawm cov khoom sib nqus yog ntau tshaj 130 degrees Celsius, thiab qee qhov ntawm lawv txawm nce mus txog ntau tshaj 200 degrees Celsius, yog li ntawd, nws yog ib txwm zoo rau lub stepping motor kom muaj qhov kub ntawm 80-90 degrees Celsius hauv qhov tsos. Yog li ntawd, qhov kub ntawm stepping lub cev muaj zog sab nrauv yog 80-90 degrees Celsius yog kiag li qub.

Lub torque ntawm lub cev muaj zog yuav txo nrog qhov nce ntawm qhov kev sib hloov ceev: thaum lub kauj ruam lub cev muaj zog tig, lub inductance ntawm winding ntawm txhua theem ntawm lub cev muaj zog yuav tsim ib tug rov qab electromotive quab yuam; qhov siab dua qhov zaus, qhov loj dua qhov rov qab electromotive quab yuam. Raws li nws qhov kev txiav txim, lub cev muaj zog theem tam sim no txo ​​qis nrog nce zaus (lossis nrawm), ua rau txo qis ntawm lub zog.

Stepping lub cev muaj zog tuaj yeem khiav ib txwm ntawm qhov qis qis, tab sis yog tias siab tshaj qhov zaus tsis tuaj yeem pib, thiab nrog lub suab ntxhi. Stepping lub cev muaj zog muaj ib qho kev ntsuas: tsis muaj load pib zaus, uas yog, lub stepping lub cev muaj zog nyob rau hauv tsis muaj-load qhov teeb meem yuav pib lub mem tes zaus, yog hais tias tus mem tes zaus siab tshaj tus nqi, lub cev muaj zog tsis tuaj yeem pib ib txwm, tej zaum yuav tshwm sim poob los yog thaiv. Nyob rau hauv cov ntaub ntawv ntawm ib tug load, qhov pib zaus yuav tsum qis dua. Yog hais tias lub cev muaj zog mus txog high speeds, lub mem tes zaus yuav tsum tau ceev, piv txwv li, pib zaus yuav tsum tsawg, thiab ces ceev mus rau qhov xav tau ntau zaus (lub cev muaj zog ntawm qis mus rau siab).

Cov khoom siv hluav taws xob rau hybrid stepper lub cev muaj zog tsav tsheb feem ntau yog ntau yam, thiab cov khoom siv hluav taws xob feem ntau yog xaiv raws li lub cev muaj zog ua haujlwm ceev thiab cov lus teb. Yog tias qhov kev ua haujlwm ntawm lub cev muaj zog yog siab lossis cov lus teb yuav tsum tau ceev, ces tus nqi hluav taws xob kuj tseem siab, tab sis yuav tsum ceev faj tias cov ripple ntawm cov khoom siv hluav taws xob yuav tsum tsis pub tshaj qhov siab tshaj plaws input voltage ntawm tus neeg tsav tsheb, txwv tsis pub tus tsav tsheb yuav puas.

Lub hwj huam mov tam sim no feem ntau txiav txim siab raws li cov zis theem tam sim no I ntawm tus neeg tsav tsheb. Yog tias siv cov khoom siv hluav taws xob tawm, cov khoom siv hluav taws xob tam sim no tuaj yeem siv li 1.1 txog 1.3 npaug ntawm I. Yog tias siv lub zog hloov hluav taws xob, qhov hluav taws xob tam sim no tuaj yeem siv li 1.5 txog 2.0 npaug ntawm I.

Thaum lub teeb liab offline DAWB tsawg, cov zis tam sim no los ntawm tus tsav tsheb mus rau lub cev muaj zog raug txiav tawm thiab lub cev muaj zog rotor nyob hauv lub xeev dawb (offline xeev). Hauv qee cov khoom siv automation, yog tias kev sib hloov ncaj qha ntawm lub cev muaj zog (manual hom) yuav tsum tsis muaj lub zog tsav, lub teeb liab dawb tuaj yeem teeb tsa qis kom coj lub cev muaj zog offline rau kev tuav haujlwm lossis hloov kho. Tom qab phau ntawv ua haujlwm tiav, DAWB teeb liab tau teeb tsa siab dua kom tswj tsis siv neeg txuas ntxiv.

11

Ib txoj hauv kev yooj yim los kho cov kev taw qhia ntawm kev sib hloov ntawm ob-theem stepper lub cev muaj zog tom qab nws tau muaj zog yog hloov pauv A + thiab A- (lossis B + thiab B-) ntawm lub cev muaj zog thiab tsav tsheb.
