Ua ntej. Lub hauv paus rau phau ntawv
Hauv cov chaw muaj kev lag luam niaj hnub kev tswj hwm, cov kauj ruam ruam ruam yog cov kev nyiam rau lawv cov cim kev sib txawv thiab kev tswj hwm txoj haujlwm. Ntawm lawv, Bipolar Stepping Tsav, raws li ib qho tseem ceeb ntawm cov kab ke sib txawv, ntsuas cov ntsuas ntau yam ntawm nws cov kev ua tau zoo. Hauv daim ntawv no, cov qauv qauv thiab kev tswj hwm ntawm Bipolar steping motors yuav tau qhia nyob rau hauv kev nthuav dav, tsom rau muab kev nkag siab zoo thiab kev paub tob.
Thib ob, tus qauv ntawm Bipolar Stansper Tsav
Bipolar Steping Tsav, Kuj tseem hu ua ob-theem plaub-xaim kauj ruam lub cev muaj zog, nws cov qauv yooj yim muaj xws li lub stator, rotor thiab winding peb ntu loj.
Tus ci
Lub stator yog lub chaw nyob ruaj ntawm ib lub zog bipolar stanser lub cev muaj zog, feem ntau muaj ntawm ntau cov hniav. Hauv Bipolar Stansper Tsav, tus hniav ntsuas hniav tau mob nrog ob-theem bipolar windings, piv txwv li, A-theem thiab B-Theem Windings. Txhua ntawm ob ntu no muaj cov kauj vab sib txawv, txhua nrog ob xaim, rau tag nrho cov xov hlau, rau tag nrho cov xov hlau, uas tau siv los tswj kev ua haujlwm ntawm lub cev muaj zog.
Tshwj xeeb, A-theem winding yog qhov txhab los ntawm stator hniav 1, thiab 7, qhov twg stator cov hniav 3 thiab 7 yog qhov txhab nyob rau hauv tib txoj kev taw qhia. Ob pawg no (stator cov hniav 1 thiab 5, thiab 7) yog qhov txhab nyob rau hauv cov qauv zoo. ua ib pab pawg.
Rotor
Lub rotor yog txoj kev sib hloov ib feem ntawm bipolar stepper tsav thiab feem ntau yog axalial magnetized cov hlau nplaum ruaj khov. Cov kab sib nqus ntawm cov hlau sib nqus ntawm cov hlau nplaum ruaj khov ib lub cev nyob hauv lub cev ntawm lub cev muaj zog, tso cai rau lub rotor kom muaj lub zog xauv txawm tias thaum tsis muaj zog. Tsis tas li ntawd, lub rotor feem ntau muaj ib tug xov tooj ntawm cov hniav (piv txwv li, 50 tus hniav) uas sib haum rau cov ces muag stator (piv txwv li, 1.8 degree lub kaum sab xis).
Windings
Cov winding ntawm bipolar stepper tsav yog qhov tseem ceeb ntawm lub cev muaj zog uas paub cov lus tsa suab ntawm lub cev muaj zog. Txij li thaum Bipolar Stans cov motors muaj ob qho coils cais, txhua tus tuaj yeem ua kom muaj kuab nyob hauv ob qho tib si, ib qho kawg ntawm txhua qhov cua yuav ua tau ib qho n lossis sawj. Cov qauv tsim no ua rau lub zog bipolar stepper ntau dua yooj yim hauv hom kev tswj hwm, uas tuaj yeem paub ntau txoj kev tswj hwm thiab ntau dua kev ua haujlwm zoo dua.
Thib peb, Tswj Kev Tswj ntawm Bipolar Stansper Tsav
Cov qauv tswj hwm ntawm bipolar stepper lub cev muaj zog tsuas yog suav nrog ib theem zuj zus, cov kauj ruam uas muaj sij hawm ib nrab.
Ib leeg-theem stepping
Ib leeg-theem stepping yog hom theem pib ntawm bipolar steping tsav. Nyob rau hauv hom no, A-theem thiab B-Theem Windings yog energized ua ntu zus, ua rau cov stator sib xeem sib nqus pauv kom haum, yog li tsav lub rotor kom tig. Tshwj xeeb, thaum ib-theem winding yog energized, rotor yuav tig hauv ib qho kev taw qhia; Thaum B-Pass winding yog energized, rotor yuav tig rau lwm txoj kev taw qhia. Los ntawm kev tswj hwm lub xeev ntawm A-theem thiab B-Theem Windings, txuas ntxiv tig ntawm lub rotor tuaj yeem ua tiav.
Ib leeg-theem stepping hom yog yooj yim thiab nkag siab yooj yim, feem ntau yog lub kaum qhov uas muaj kev tswj tau txaus yog qhov yuav tsum tau ua.
Tag nrho-kauj ruam dhau
Cov kauj ruam feem ntau yog ib qho ntawm cov qauv tswj cov qauv siv rau Bipolar StansPerot. Hauv hom no, A-theem thiab B-Theem Windings yog energized lossis de-energized nyob rau tib lub sij hawm kom ua tiav kev sib hloov-kauj ruam ntawm lub rotor. Tshwj xeeb, thaum ib-theem winding yog energized thiab b-theem winding yog de-energized, rotor yuav tig hauv ib qho kev taw qhia los ntawm ib qho kev sib dhos; Thaum B-Pass winding yog energized thiab ib-theem winding yog de-energized, rotor yuav tig rau lwm txoj kev taw qhia los ntawm tib lub kaum sab xis. Los ntawm kev tswj hwm lub xeev ntawm A-theem thiab B-Theem Windings, txuas ntxiv sib txuas ntawm lub rotor tuaj yeem pom tau.
Cov kauj ruam uas muaj tag nrho muaj qhov zoo ntawm lub kaum sab xis me me, yog li nws tau siv dav hauv cov ntawv thov kev tswj hwm. Piv txwv li, hauv cov khoom siv hauv chaw ua haujlwm xws li cov tshuab luam ntawv thiab cov neeg soj ntsuam, hom bipolar stepper feem ntau siv cov kauj ruam tagnrho-kauj ruam los tswj hwm lub taub hau luam tawm lossis ntsuas lub taub hau.
Ib nrab-kauj ruam
Ib nrab-kauj ruam yog ib hom kev tswj hwm ntau hom kev tswj hwm rau Bipolar StansPer motors. Hauv hom no, ib nrab-kauj ruam kev sib hloov ntawm lub rotor tuaj yeem ua tiav los ntawm ib feem ntawm cov coils hauv ib-theem thiab b-thase windings kom energized los yog de-energized. Tshwj xeeb, thaum ib feem ntawm cov kauj hauv ib-theem winding yog energized thiab ib feem ntawm cov kauj hauv b--,, rotor yuav tig los ntawm ib nrab ntawm ib kauj ruam hauv ib kauj ruam hauv ib kauj ruam hauv ib kauj ruam; Thaum ib feem ntawm cov kauj hauv b-theem winding yog energized thiab ib feem ntawm cov kauj hauv ib-energized, rotor yuav tig los ntawm ib nrab ib kauj ruam hauv lwm kauj ruam. Los ntawm kev tswj hwm lub xeev ntawm cov kauj hauv cov kauj vab hauv ib-theem thiab b-theem windings, txuas ntxiv ib nrab-kauj ruam kev sib hloov ntawm lub rotor tuaj yeem pom tau.
Ib nrab-kauj ruam hom muaj qhov zoo ntawm cov kauj ruam me me thiab siab dua qhov raug, thiab yog li ntawd dav siv nyob rau hauv cov ntawv thov tswj. Piv txwv li, hauv kev ntsuas cov twj paj nruag, thiab cov khoom siv kho mob feem ntau siv ib nrab ntawm txoj kev tswj hwm thiab kev tswj hwm.
Plaub, Ntsiab Lus
Bipolar StansPer Motors Ua lub luag haujlwm tseem ceeb hauv kev muaj tshuab kev lag luam automation kev tswj nrog lawv cov qauv tshwj xeeb thiab hom tswj hwm. Los ntawm kev nkag siab tob ntawm cov qauv thiab tswj hwm nws cov txheej txheem zoo dua thiab kev siv cov tshuab ua lag luam.
