A three-phase induction motor develops 20 kW when running at 90% efficiency, at a power factor of 0,45 lagging. Calculate the readings on each of the two watt meters connected to read the input power.

The synchronous motor is an AC electric type motor where at a steady-state the shaft rotation is synchronized with the supply current variable-frequency. To an integral number of AC cycles, the rotation period is exactly equal. The stator of the motor in…
