Global Meps Guide Kwa Otsika Voltage Motors

Kufunika kowonjezereka kwa mphamvu zamagetsi kuti kupititse patsogolo chitukuko chapadziko lonse lapansi kumafuna kuti pakhale ndalama zochulukirapo pakupangira magetsi.Komabe, kuwonjezera pakukonzekera kwanthawi yayitali komanso kwakanthawi, ndalamazi zimadalira zachilengedwe, zomwe zili
kuchepa chifukwa cha kupsinjika kosalekeza kwa chilengedwe.Choncho, njira yabwino kwambiri yosungira mphamvu zamagetsi pakanthawi kochepa ndikupewa kuwonongeka ndikuwonjezera mphamvu zamagetsi.Magalimoto amagetsi amagwira ntchito yayikulu munjira iyi;kuyambira 40%
kufunikira kwa mphamvu zapadziko lonse lapansi kukuyerekezeredwa kuti zikugwirizana ndi kugwiritsa ntchito magalimoto amagetsi.

Chifukwa cha kufunikira kochepetsa kugwiritsa ntchito mphamvu komanso kutulutsa mpweya wa carbon dioxide, Maboma ambiri padziko lonse lapansi akhazikitsa Malamulo am'deralo, omwe amadziwikanso kuti MEPS (Minimum Energy Performance Standards) kumitundu yambiri ya zida,
kuphatikizapo magalimoto amagetsi.

Ngakhale zofunikira zenizeni za MEPSzi zimasiyana pang'ono pakati pa mayiko, kukhazikitsidwa kwa mfundo zachigawo monga ABNT,IEC,MG-1, yomwe imatanthawuza kuchuluka kwa magwiridwe antchito ndi njira zoyesera kuti zitsimikizire izi, imalola kukhazikika kwa matanthauzidwe, muyeso ndi mawonekedwe osindikizira kuti azigwira bwino ntchito pakati pa opanga magalimoto, kupangitsa kusankha koyenera kwa ma mota.

mphamvu zamagetsi zama motors atatu omwe si ma brake motors, Ex eb kuchuluka kwa ma motors otetezeka, kapena zina
Ma motors otetezedwa ndi kuphulika, omwe ali ndi mphamvu yofanana kapena kupitirira 75 kW ndi yofanana kapena pansi pa 200 kW,
2, 4, kapena 6 mitengo, zigwirizane ndi osacheperaIE4mulingo wochita bwino womwe wafotokozedwa mu Table 3.

Kuti mudziwe kuchuluka kwamphamvu kwa ma motors 50 Hz okhala ndi mphamvu zovotera PN zapakati pa 0,12 ndi 200 kW zomwe sizinaperekedwe mu Matebulo 1, 2 ndi 3, njira zotsatirazi zizigwiritsidwa ntchito:
ηn = A* [log1o(Pv/1kW)]3 + BX [log10(PN/1kW)]2 + C* log10(PN/1kW)+ D.
A, B, C ndi D ndi ma coefficients ophatikiza omwe amayenera kutsimikiziridwa malinga ndi Table 4 ndi 5.
