However, in alternating current (AC) the electric current changes direction at 50 times per second (50 Hz … If it is a lead acid, zinc, or NiCad the voltage if carefully done gives information about the state of charge of a battery. We don't collect information from our users. Assuming a power factor of 1, the electrical power supplied to a motor is given by the voltage drop across the motor multiplied by the current supplied to the motor (P = VI). The calculators below can be used to calculate electric motor amps, horsepower and 3-phase kVa. Calculate: 1) The starting current. The motor wire size should be designed to handle this in rush current, as well as handle a continuous full-load current of the motor. Electric power is defined as the rate, per unit time, at which an electric circuit transfers its electrical energy. 2) The back e.m.f. An additional text field will appear below the voltage in volts text field requiring you to enter the power factor. It can either be an AC-Single phase or an AC- three phase. The easiest way to measure this power is before the motor controller where the current is still DC and the voltage is near constant. 9/25/20 - 150 Millions Drive Calculation - thanks for using eCalc!
