Buku Lotsogolera Padziko Lonse la Meps la Magalimoto Otsika Voltage

Kufunika kwakukulu kwa mphamvu zamagetsi kuti zipititse patsogolo chitukuko cha dziko lonse kumafuna ndalama zambiri nthawi zonse popanga magetsi. Komabe, kuwonjezera pa kukonzekera kovuta kwa nthawi yayitali komanso yapakatikati, ndalamazi zimadalira zinthu zachilengedwe, zomwe ndi
Kuchepa mphamvu chifukwa cha kupsinjika kosalekeza pa chilengedwe. Choncho, njira yabwino kwambiri yosungira mphamvu pakanthawi kochepa ndikupewa kuwononga mphamvu ndikuwonjezera kugwiritsa ntchito bwino mphamvu. Ma mota amagetsi amachita gawo lalikulu pa njira iyi; popeza pafupifupi 40%
Kufunika kwa mphamvu padziko lonse lapansi kukuyerekezeredwa kuti kukugwirizana ndi kugwiritsa ntchito injini zamagetsi.

Chifukwa cha kufunika kochepetsa kugwiritsa ntchito mphamvu ndi kutulutsa mpweya wa carbon dioxide, Maboma ambiri padziko lonse lapansi akhazikitsa Malamulo am'deralo, omwe amadziwikanso kuti MEPS (Minimum Energy Performance Standards) ku mitundu yosiyanasiyana ya zida,
kuphatikizapo ma mota amagetsi.

Ngakhale zofunikira zenizeni za MEPS izi zimasiyana pang'ono pakati pa mayiko, kukhazikitsidwa kwa miyezo ya chigawo monga ABNT,IEC,MG-1, yomwe imafotokoza milingo ya magwiridwe antchito ndi njira zoyesera kuti idziwe magwiridwe antchitowa, imalola kukhazikika kwa tanthauzo, muyeso ndi mtundu wa zofalitsa kuti zidziwike bwino pakati pa opanga magalimoto, zomwe zimapangitsa kuti kusankha injini moyenera kukhale kosavuta.

kugwiritsa ntchito bwino mphamvu kwa ma mota a magawo atatu omwe si ma brake motors, Ex eb increased safety motors, kapena zina
Ma mota otetezedwa ndi kuphulika, okhala ndi mphamvu yofanana kapena yoposa 75 kW komanso yofanana kapena yochepera 200 kW, okhala ndi
Mizati 2, 4, kapena 6, iyenera kufanana ndiIE4mulingo wa magwiridwe antchito womwe wafotokozedwa mu Table 3.

Kuti mudziwe mphamvu zochepa za ma mota a 50 Hz okhala ndi mphamvu zotulutsa PN pakati pa 0,12 ndi 200 kW zomwe sizinaperekedwe mu Matebulo 1, 2 ndi 3, njira yotsatirayi iyenera kugwiritsidwa 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 ophatikizana omwe ayenera kudziwika malinga ndi Matebulo 4 ndi 5.
