The magnetic saturation of the machine can be ignored the


A 2.7-kW, 220-V, 4-pole, 60-Hz induction machine, which has following equivalent circuit parameters in per unit, is running in the steady state at 1810 r/min with no load through a variable-voltage variable-frequency (VVVF) inverter. The input frequency of the stator voltage has been changed to 58 Hz in step. The speed of the machine is kept as constant because of the large inertia of the drive system and the machine is again running in the steady state with the 58-Hz source voltage. Regardless of the frequency, the magnitude of the stator voltage is always 220 V in line-to-line rms. The magnetic saturation of the machine can be ignored. The harmonics in the current and voltage to the machine can be ignored. Calculate the active power (watts) to the machine from the VVVF inverter.
