Qhov txawv ntawm NEMA motors thiab IEC motors.
Txij li xyoo 1926, National Electrical Manufacturers Association (NEMA) tau teeb tsa cov qauv rau cov motors siv hauv North America. NEMA tsis tu ncua hloov tshiab thiab tshaj tawm MG 1, uas pab cov neeg siv xaiv thiab siv lub cev muaj zog thiab cov tshuab hluav taws xob kom raug. Nws muaj cov ntaub ntawv qhia txog kev ua tau zoo, kev ua tau zoo, kev nyab xeeb, kev sim, kev tsim khoom, thiab kev tsim cov khoom siv hluav taws xob tam sim no (AC) thiab ncaj qha tam sim no (DC) motors thiab generators. Lub International Electrotechnical Commission (IEC) tau teeb tsa cov qauv rau lub cev muaj zog rau lwm lub ntiaj teb. Zoo ib yam li NEMA, IEC luam tawm tus qauv 60034-1, Phau Ntawv Qhia rau Tsav Tsheb rau Kev Lag Luam Ntiaj Teb.
Dab tsi yog qhov txawv ntawm NEMA tus qauv thiab tus qauv IEC? Tuam Tshoj tus qauv tsav tsheb siv IEC (European standard) thiab NEMA MG1 yog tus qauv Asmeskas. Hauv paus, ob lub hauv paus yog tib yam. Tab sis nws kuj txawv me ntsis hauv qee qhov chaw. Tus qauv NEMA thiab IEC tus qauv sib txawv hauv qhov kev siv lub zog siv hluav taws xob thiab rotor kub nce. Lub zog siv hluav taws xob ntawm NEMA lub cev muaj zog yog 1.15, thiab IEC (Tuam Tshoj) lub zog hluav taws xob yog 1.Txoj kev ntawm kev kos lwm qhov tsis sib txawv, tab sis cov ntsiab lus tseem ceeb yog tib yam.
Sib piv sib txawv
Feem ntau, qhov sib txawv tseem ceeb yog qhov sib txawv loj hauv kev siv tshuab thiab kev teeb tsa. IEC yog nruj dua nyob rau hauv cov nqe lus ntawm sealing. Hais txog kev xav tau ntawm hluav taws xob, Nema hluav taws xob yuav tsum muaj lub sij hawm ntev overload ntawm 1.15 thiab cov kev cai siab rwb thaiv tsev feem ntau pom hauv UL.
Kev sib piv ntawm qhov sib txawv tseem ceeb ntawm Nema thiab IEC motors
Kev sib piv ntawm Nema thiab IEC lub cev muaj zog qhov ntau thiab tsawg
Thaum NEMA thiab IEC muaj ntau qhov sib xws, muaj qee qhov sib txawv ntawm ob tus qauv tsav tsheb. NEMA lub tswv yim hais txog kev tsim qauv zoo dua rau kev siv dav dua. Kev yooj yim ntawm kev xaiv thiab qhov dav ntawm daim ntawv thov yog ob lub hauv paus ncej hauv nws lub tswv yim tsim; IEC tsom rau kev siv thiab kev ua haujlwm. Kev xaiv cov cuab yeej IEC yuav tsum muaj kev paub ntau dua ntawm daim ntawv thov, suav nrog kev thauj khoom lub cev, lub voj voog lub luag haujlwm, thiab tag nrho cov khoom thauj tam sim no. Tsis tas li ntawd, NEMA tsim cov khoom siv nrog cov yam ntxwv ntawm kev nyab xeeb uas yuav siab li 25% kev pabcuam, thaum IEC tsom rau qhov chaw thiab txuag nqi.
IE5 Energy Efficiency Class.
IE5 chav kawm ua haujlwm tau zoo yog kev faib tawm lub cev muaj zog tsim los ntawm International Electrotechnical Commission (IEC) uas qhia txog qib siab tshaj plaws ntawm kev siv hluav taws xob hauv kev tsim lub cev muaj zog. Hauv Suav teb, IE5 chav kawm ua haujlwm tau zoo nyob rau hauv txoj kab nrog lub tebchaws's kev cog lus los puag lub zog txuag technologies thiab txo nws cov pa roj carbon hneev taw. IE5 lub cev muaj zog ua kom muaj zog ua haujlwm zoo, txo qis zog poob thaum lub sijhawm ua haujlwm, ua tiav cov txiaj ntsig tseem ceeb thiab cov txiaj ntsig ib puag ncig.
NEMA tsis tau muab cov ntsiab lus txhais rau IE5 hauv North American lag luam, txawm hais tias qee cov tuam txhab lag luam muag VFD-tsav motors li.“super-advanced efficiency.”Tib lub tswv yim siv tau rau kev ua tiav IE5 qhov sib npaug ntawm cov qib kev ua haujlwm nrog kev sib txawv ntawm qhov nrawm nrawm ntawm tag nrho thiab ib nrab loads. Integrated motor drives siv ferrite-pab synchronous reluctance thev naus laus zis yog lwm qhov kev daws teeb meem uas muab IE5 qib ntawm kev ua tau zoo thiab ua kom yooj yim teeb tsa thaum tshem tawm cov kab hluav taws xob kim thiab lub sijhawm teeb tsa.
Vim li cas lub zog efficiency yog lub ntsiab lus kub?
Lub cev muaj zog thiab lub cev muaj zog suav txog kwv yees li 53% ntawm kev siv hluav taws xob thoob ntiaj teb. Cov motors tuaj yeem siv tau rau 20 xyoo lossis ntau dua, yog li lub zog siv los ntawm cov motors tsis muaj txiaj ntsig tau khaws cia hauv lub neej ntawm cov khoom, ua rau muaj kev ntxhov siab tsis tsim nyog ntawm daim phiaj. Los ntawm kev tsom mus rau kev xaiv lub cev muaj zog zoo tshaj plaws los txhim kho tag nrho cov kev ua haujlwm zoo thiab zam CO2 emissions, kev cuam tshuam ib puag ncig thiab kev txuag nqi tuaj yeem txo, uas tuaj yeem xa mus rau cov neeg siv khoom. Ntxiv nrog rau kev txo cov roj tsev cog khoom thiab cov nqi hluav taws xob, cov motors muaj peev xwm kuj tuaj yeem txhim kho huab cua zoo, txo cov khoom siv downtime, thiab nce cov neeg siv khoom kawg.
