An additional text field will appear below the voltage in volts text field requiring you to enter the power factor. another thing to remember is in an esc with a linear bec, the amp rating is usually the max and not "real world". 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). Electrical formulas - electrical calculation - power calculation- hp horsepower - hp to amps - ampere unit of electric current. Electric power is defined as the rate, per unit time, at which an electric circuit transfers its electrical energy. You can use the Electrical calculator to find the current in single, 2, and 3 phase motor circuits as well as in dc circuits. Rating (P). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts).
