ηvu=0,99– to‘g‘rilovchiqurilmaning KPDsi (ijobiy ta’sir koeffitsenti).
YUk tortuvchi generatorning quvvati:
Pr=[Ne-(1-ηvsp)Ne]nd = 2534.6-(1-0.84)*2534.6)/0.85 = 1809.7 kVt (2)
YUk tortuvchi elektrodvigatelning quvvati:
Pdpr=Pr/m = 1809.7/6 = 301.61 kVt
Bunda, m - yuk tortuvchi elektrodvigatellar soni.
Namunadagiteplvovoz va yuk tortuvchi elektrodvigatellarning quvvatiga qarab 2-jadval asosida o‘z quvvati bilan loyihadagi teplovoz elektrodvigatelining yuk tortishiga yaqin bo‘lgan yuk tortuvchi elektrodvigatel markasi tanlab olinadi.
Ko‘zda tutilgan Pdpr=301,61kVtga eng yaqin bo‘lgan yuk tortuvchi EDT-200B markali Rdpr=307kVt quvvatli yuk tortuvchi elektrodvigatel hisoblanadi.
Ushbu elektrodvigatel uchun 2-jadval bo‘yicha regressiv koeffitsient tKMiladi va uning yordamida teplovoz – namunaning elektromexanik xarakteristikasi tuziladi.
