Motor power equation
Nettet15. apr. 2024 · Power factor of motor formula. PF = P / S . where. PF = power factor = Cos α. P = √3V I cos α =active (true or real) power (Watts) S = √3V I= Apparent power (VA, volts amps) hence, Power factor of motor formula is. Cos α =√3 VI Cos α / √3 VI. From the following diagram, you can easily understand why the power factor is cosine ... NettetUse this formula to estimate motor horsepower. Horsepower (hp) = Voltage x Amperage x % EFF x power factor x 1.73/746. Where: Voltage is the average of the three voltages measured: (A-B + A-C + B-C)/3. Amperage is the average current of the three phase measured: (A+B+C)/3 % EFF is motor efficiency per motor nameplate. Power factor is …
