AC single phase watts to amps calculation. The phase current I in amps (A) is equal to the power P in watts (W), divided by the power factor PF times the RMS voltage V in volts (V): Induction motor no load: 0.35: Resistive oven: 1: Synchronous motor: 0.9: Watts to amps table (120V) Power (W) Voltage (V) Current (A) 10 watts: 120 volts: 0.
Learn MoreP (kW) = (I (Amps) × V (Volts) × PF × 1.732) ÷ 1,000. As we can see, the electrical power in the 3-phase AC circuit depends on: I (Amps): Electrical current, measured in amps. The more amps

Learn MoreIndustry and home emergency generators use three-phase electric motors. · Only in this case, multiply the result by 1.732. · Active (real or true)
Learn MorePower Factor- PF - three phase motors(0 - 1) RLA - "Running Load Amps"- current drawn during normal operation of electric motor. FLA - "Full Load Amps"- amount of current drawn when full-load torque and horsepower is reached for the motor. FLAis usually determined in laboratory tests. Note!- in the calculator above FLAis RLA + 25%. 1 hp = 0.745 kW
Learn MoreCalculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV (sqrt 3). 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). Convert watts to kilowatts by dividing the number of watts by 1,000.
