Kuwedzera kwekuda kwesimba remagetsi kuti rirambe richikura pasi rose kunoda mari yakawanda inogara ichishandiswa mukugadzira magetsi. Zvisinei, pamusoro pekuronga kwakaoma kwenguva refu nepakati, mari iyi inotsamira pazviwanikwa zvechisikigo, izvo zviri
Kupera simba nekuda kwekumanikidzwa kuri kuramba kuchiitika nharaunda. Saka, nzira yakanakisisa yekuchengetedza simba kwenguva pfupi ndeyekudzivirira kutambisa simba uye kuwedzera kushanda zvakanaka kwesimba. Mota dzemagetsi dzinoita basa guru muhurongwa uhwu; sezvo dzinenge 40%
Kudiwa kwesimba pasi rose kunofungidzirwa kuti kwakabatana nekushandiswa kwemota dzemagetsi.
Nekuda kwekuda uku kwekuderedza kushandiswa kwesimba uye kuburitswa kwecarbon dioxide, Hurumende zhinji pasi rose dzakaisa Mitemo yemuno, inozivikanwawo seMEPS (Minimum Energy Performance Standards) kumhando dzakasiyana dzemidziyo,
kusanganisira mota dzemagetsi.
Kunyange hazvo zvinodiwa neMEPS idzi zvichisiyana zvishoma pakati penyika, kushandiswa kwemitemo yedunhu yakaita seABNT,IEC,MG-1, iyo inotsanangura mazinga ekushanda zvakanaka uye nzira dzekuyedza kuona kushanda zvakanaka uku, inobvumira kurongeka kwetsananguro, kuyerwa uye fomati yekuburitswa kwedata rekushanda zvakanaka pakati pevagadziri vemota, zvichiita kuti kusarudzwa kwemota kwakakodzera kuve nyore.
kushanda zvakanaka kwemagetsi emota dzemaphase matatu dzisiri mota dzemabhureki, mota dzekuchengetedza dzakawedzera, kana dzimwe mota
mota dzinodzivirirwa nekuputika, dzine simba remagetsi rakaenzana kana kupfuura 75 kW uye rakaenzana kana pasi pe200 kW,
Matanda maviri, mana, kana matanhatu, anofanira kuenzana neanengeIE4mwero wekushanda zvakanaka wakaratidzwa muTafura 3.
Kuti uone kushanda kushoma kwemamota e50 Hz ane simba rePN riri pakati pe0,12 ne200 kW risingawanikwe muTafura 1, 2 ne3, fomura inotevera inofanira kushandiswa:
ηn = A* [log1o(Pv/1kW)]3 + BX [log10(PN/1kW)]2 + C* log10(PN/1kW)+ D.
A, B, C naD ndiwo ma coefficients e interpolation anofanira kutsanangurwa zvichienderana neTafura 4 ne5.
