WebA loads: 400V2 kVA induction motors at 0.707 lagging power factor, and synchronous motor of 400KVA at unity power factor. Its recommended to operate the synchronous machine in over-excited mod with the same voltage to improve the power factor of the factory to This problem has been solved! WebkVA (kilovolt-Amperes) = Input Voltage x Input Amperes (Current) x 1.73 / 1000 The only difference between kW (kilowatts) and kVa (kilovolt-amperes) is the power factor. The power factor, unless known, is always an approximation. Converting kVA to kW kVA x power factor (.85 is a conservative number) = kW

The … WebJan 11, 2024 · Motor Slip. Slip of a motor can be found from the formula: s = (η sync -η m )/ η sync * 100. η sync = Speed of magnetic field. η m = Mechanical shaft speed. Calculation: The rotor speed of a 4 pole induction motor at 50 Hz is 1200 r/min. Calculate its slip. Solution: Rotor speed = η m = 1200 r/min. Where η sync = 120 * 50 / 4 = 1500 r/min. the poky little puppy song
