Kev tawm tswv yim
Txij li thaum yug me nyuam ntawm cov tshuab tsis txhuam, Cov nyhuv cov nyhuv quav tau ua lub zog tseem ceeb rau kev tawm tswv yim. Txij li peb theem-theem tswj tsuas tau peb lub sensors thiab cov nqi chav tsev tsawg tsawg xwb, lawv feem ntau qhov kev xaiv pheej yig tshaj plaws rau kev hloov ntawm qhov kev xav ntawm BOM nqi. Ib lub nyhuv quav uas pom tias txoj hauj lwm ntawm lub rotor yog nyob hauv lub stator ntawm lub tshuab kom tus transistors nyob rau hauv peb choj choj raug hloov mus tsav tsheb. Qhov peb nyhuv sensor outputs feem ntau yog hais tias U, V, thiab W channels. Txawm hais tias cov nyhuv nyhuv ntawm cov cuab yeej ua haujlwm tau zoo los daws qhov teeb meem ntawm BLDC lub cev, lawv tsuas pom ib nrab ntawm cov kev cai ntawm BLDC systems.
Txawm hais tias cov nyhuv nyhuv cov cuab tam ua rau tus maub los tsav tsav BLDC, hmoov tsis nws tswj tsis txwv thiab kev taw qhia. Hauv peb-theem motors, Cov nyhuv cov nyhuv quav tau tsuas yog muab qhov chaw nyob ntawm txhua qhov hluav taws xob. Raws li cov xov tooj ntawm cov khub khub nce, cov xov tooj ntawm cov hluav taws xob cycles rau cov khoom tig tau nce, thiab raws li kev siv BLDC ua ntau dua, qhov kev xav tau rau txoj hauj lwm meej qhov nce ntxiv. Los xyuas kom meej meej thiab kho kom tiav, BLDC system yuav tsum muab cov ntaub ntawv qhia qhov tseeb rau lub sij hawm uas tus maub los mus saib tau tsis yog qhov ceev thiab kev taw qhia, tab sis kuj mus ncig deb thiab qhov chaw.
Yuav kom ua tau raws li qhov xav tau kom muaj ntau qhov chaw cov ntaub ntawv, ib qho kev daws teeb meem yog ntxiv rau qhov kev hloov tshiab ntawm qhov hloov tshiab rau BLDC motors. Txuas ntxiv, ntxiv rau cov nyhuv quav, cov cim ntxiv qhov ntxiv rau qhov kev sib txuas lus qis dua. Cov nyhuv nyhuv nyhuv yog siv rau kev sib tsoo ntawm lub cev, thaum siv cov cim encoder, los mus khiav txoj hauj lwm, kev sib tw, kev ceev thiab kev siab dua. Vim tias cov nyhuv quav nyhav nyiab qhia txog txoj hauj lwm tshiab tsuas yog thaum txhua lub xeev Hall hloov, nws cov lus yog tsuas yog rau 6 lub xeev ib lub voj voog; rau kev siv lub cev muaj zog, nws tsuas yog rau lub xeev rau ib lub voj voog twg. . Qhov kev xav tau ntawm ob qho no yog negligible piv rau ib qho incremental encoder uas yuav muab tau cov phiaj xwm hauv phav phav PPRs (naj npawb ntawm pulses ib kiv puag ncig) uas tuaj yeem seev rau plaub zaug pes tsawg lub xeev hloov.
mus sum
High-precision, nruj tswj loops muab BLDC motors ib ntug hauv ntau qhov chaw. Ua kom cov neeg ua tau zoo dua yog tias tsis muaj hwj chim, muaj txiaj ntsim dua, thiab tswj kom zoo dua rau BLDC lub sijhawm ua haujlwm rau cov neeg siv tas. Tam sim no, BLDC cov cav tau siv ntau yam kev lag luam, nrog rau kev kho mob phom sij, tsheb tsis tsav tsheb, kev sib txuas ntawm cov kab automation, thiab lwm yam, thiab sai sai no yuav tau txais ib qho chaw hauv ntau qhov chaw tsis tau pom. Lub BLDC lub tsev lag luam loj hlob tuaj, thiab cov kev cai rau BLDC cov kev lag luam tseem nyob li qub: qhov kev ua lag luam xav tau kev ua haujlwm siab thiab ua haujlwm ntev nrog cov uas tsis raug nqi tsawg, muaj kev cuam tshuam cov tswv yim. Thaum siv BLDC motors, cov AMT31 Series encoders tseg sij hawm tseem ceeb thaum kev teeb tsa thaum simplifying kev tsim kho thiab kev tsim. Nrog nws cov cwj pwm, qhov peev xwm los ua kom tiav lub programming thiab zeroing chaw nyob hauv vib nas this, thiab compatibility nrog AMTViewpointGUI, AMT31 encoder zoo haum rau kev xav tau ntawm lub khw BLDC ceev.
