For a 1-phase supply with power rating in kilowatt (kW): For a 1-phase supply with power rating in horsepower (hp): Note that the motor rated full load current is specified on the motor datasheet and stamped on the motor nameplate. However, this calculator is useful when only the motor rating is available and an estimate of the current is required.
Mar 19, 2017· = 2.49 kW Unit consumed = Power in kW X numbers of hours of operation. = 2.49 X 24 units = 59.76 units. Hence units burnt (consumed) by 3 HP motor in 24 hours will be 59.76, if the motor efficiency is 90% and motor is fully loaded. In actual, motor load will be less than full load and units consumed will be less accordingly.
