Dec 13,  · For three phase motor amps calculation, the below formula is used. 3 phase motor current calculation formula is P/ (√3xVxPfxEff) or P/ (1.732xVxPfxEff) Both are the same. So our motor power is 15KW with 15 x 1000 = 15000 Watts. Motor volts are 380 volts, Eff is 0.89 and PF is 0.85 according to the above nameplate.

How to Convert Horsepower to Amps · Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts · Watts = Horsepower × 746 · Watts = Watts / η · Amps = Watts ÷ Volts · Amps = HP 

To calculate the Amps for a three phase circuit, divide the figure by 1.732. Need help from the electrically gifted. Three-Phase Voltage Imbalance . Voltage imbalance is a motor killer. It causes poor motor performance and increases winding heat, which leads to premature failure.

Mar 01,  · For example, take a 400 V (V LL) three phase system with the following loads: phase 1 = 80 A, phase 2 = 70 A, phase 3 = 82 A the line to neutral (phase) voltage V LN = 400/√3 = 230 V phase 1 apparent power = 80 x 230 = 18,400 VA = 18.4 kVA phase 2 apparent power = 70 x 230 = 16,100 VA = 16.1 kVA

Calculate 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.
