How Do You Calculate The KW Of A 3 Phase Motor?
How Do You Calculate The KW Of A 3 Phase Motor? For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000. How do you calculate kW rating? Multiply the motor voltage by the full-load current. The result is in watts. Divide watts by 1,000 to give
