Isidingo esikhulayo samandla kagesi ukuze kusekelwe intuthuko yomhlaba wonke sidinga ukutshalwa kwezimali okuqinile okuqhubekayo ekukhiqizweni kwamandla kagesi. Kodwa-ke, ngaphezu kokuhlela okuyinkimbinkimbi kwesikhathi esiphakathi nesikhathi eside, lokhu kutshalwa kwezimali kuncike ezintweni zemvelo, okuyizinto
ukuwohloka ngenxa yokucindezeleka okuqhubekayo emvelweni. Ngakho-ke, isu elingcono kakhulu lokugcina ukutholakala kwamandla esikhathini esifushane ukugwema ukuchitha imali nokwandisa ukusebenza kahle kwamandla. Ama-motor kagesi adlala indima enkulu kuleli cebo; njengoba cishe angu-40%
Ukufunwa kwamandla emhlabeni wonke kulinganiselwa ukuthi kuhlobene nokusetshenziswa kwezimoto zikagesi.
Ngenxa yalesi sidingo sokunciphisa ukusetshenziswa kwamandla kanye nokukhishwa kwe-carbon dioxide, ohulumeni abaningi emhlabeni wonke babeke iMithethonqubo yendawo, eyaziwa nangokuthi i-MEPS (Minimum Energy Performance Standards) ezinhlotsheni eziningi zemishini,
kufaka phakathi ama-motor kagesi.
Nakuba izidingo ezithile zale MEPS zihluka kancane phakathi kwamazwe, ukusetshenziswa kwezindinganiso zesifunda njenge-ABNT,I-IEC,I-MG-1, echaza amazinga okusebenza kahle kanye nezindlela zokuhlola ukuze kunqunywe lokhu kusebenza kahle, ivumela ukuhlelwa kwencazelo, ukulinganisa kanye nefomethi yokushicilelwa kwedatha yokusebenza kahle phakathi kwabakhiqizi bezimoto, okwenza kube lula ukukhetha izinjini ezifanele.
ukusebenza kahle kwamandla kwamamotha anezigaba ezintathu angewona amamotha amabhuleki, amamotha okuphepha akhulisiwe e-Ex eb, noma amanye
ama-motor avikelwe ukuqhuma, anomphumela olinganiselwe olingana noma ongaphezu kuka-75 kW kanye nolingana noma ongaphansi kuka-200 kW,
Izinsika ezi-2, 4, noma ezi-6, kufanele zihambisane okungenani ne-I-IE4izinga lokusebenza kahle elichazwe kuThebula 3.
Ukuze kutholakale ukusebenza kahle okuncane kwama-motor angu-50 Hz anemiphumela yamandla elinganisiwe engu-PN ephakathi kuka-0,12 no-200 kW enganikezwanga kumaThebula 1, 2 no-3, ifomula elandelayo kufanele isetshenziswe:
ηn = A* [log1o(Pv/1kW)]3 + BX [log10(PN/1kW)]2 + C* log10(PN/1kW)+ D.
A, B, C kanye no-D yizinhlanganisela zokuxutshwa okufanele zinqunywe ngokuya ngamaThebula 4 no-5.
