How do you calculate the starting current of a 3 phase motor? e.g. a 10 hp motor is rated at 7.46 kw, so on starting it may draw 75 kw. On 480 volts 3 phase, the amperage will be I = W / (E x 1.73) = 75,000 / (480 x 1.73) = 90.4 amps. The actual starting current depends on the type of starter it's wired to, and what motor you have.

Step 1: Multiply the AC voltage by the motor efficiency, the power factor, the current and the square root of 3. For example, if the motor is 220 V ac, it has an efficiency of 80%, the power factor is 0.9 and a correinte of 54.4A, you must Multiply 220 V ac by 0.8 (80%) by 0.9 by √3 (square root of 3) and by 54.4A to obtain 274.35 (220Vacx0.8
