Kuwedzera kuri kudiwa kwesimba remagetsi kusimudzira budiriro yepasirese kunoda kusimba mari yakawanda mukugadzira magetsi.Nekudaro, pamusoro pekuronga kwakaoma kwepakati uye kwenguva refu, mari iyi inotsamira pazvinhu zvakasikwa, izvo zviri
kupera simba nekuda kwekusagadzikana kwenzvimbo.Nzira yakanakisisa, naizvozvo, kuchengetedza simba rekupa munguva pfupi ndeyekudzivisa kuparara uye kuwedzera simba rekushandisa.Magetsi emagetsi anoita basa guru muchirongwa ichi;kubva ku40%
yekudiwa kwesimba repasi rose inofungidzirwa kuve ine hukama nemagetsi mota application.
Nekuda kwekuda uku kuderedza kushandiswa kwesimba uye kubuda kwecarbon dioxide, Hurumende zhinji pasi rese dzakaisa Mitemo yemuno, inozivikanwawo seMEPS (Minimum Energy Performance Standards) kumhando dzakawanda dzemidziyo,
kusanganisira magetsi emagetsi.
Nepo izvo zvinodikanwa zveMEPS izvi zvichisiyana zvishoma pakati penyika, kuitwa kwemazinga ematunhu akadai seABNT,IEC,MG-1, iyo inotsanangura mazinga ekushanda uye nzira dzekuyedza kuona izvi zvinogoneka, inobvumira kumisikidzwa kwetsanangudzo, kuyerwa uye kuburitswa kwefomati ye data inoshanda pakati pevagadziri vemotokari, kurerutsa kusarudzwa kwemotor.
kugona kwesimba kwematatu-chikamu mota dzisiri mabhureki mota, Ex eb yakawedzera kuchengetedza mota, kana zvimwe.
kuputika-dzivirirwa mota, ine yakatemerwa kubuda yakaenzana kana kupfuura 75 kW uye yakaenzana kana pasi pe200 kW, ine
2, 4, kana 6 mapango, achaenderana nechero iwoIE4nhanho yekubudirira yakanyorwa muTafura 3.
Kuti uone hushoma hwemamotor makumi mashanu Hz ane akatemerwa magetsi anobuda PN ari pakati pe0,12 ne200 kW asina kupihwa muTable 1, 2 uye 3, inotevera formula ichashandiswa:
ηn = A* [log1o(Pv/1kW)]3 + BX [log10(PN/1kW)]2 + C* log10(PN/1kW)+ D.
A, B, C uye D ndiwo makoefifiti ekududzira anofanirwa kutariswa maererano neTable 4 ne5.
