Calculate the efficiency of motor at different loads

Calculation : Motor input = VIN PUT × IIN PUT %3D Generator output = Vout put . TOUTT PUT %3D PR losses in generator = 1,'Ra+ If R, %3D Motor output = generator input Generator input = generator output + I R loss in generator + constant loss (Pc- CA Neglect the Pc in calculation Motor efficiency output inрut x 100 Eb. la Motor torque developed (Tdeveloped) N.m %3D
