Determining Motor Power factor

Power in a single phase motor

Power = E x I x PF

What is the power output of a motor that is operating at 230V single phase drawing 12 amps with a watt meter reading of 1800 watts.

Power = (I) x (E) x (PF) = Watts

Power = (12) x (230) x (0.65) = 1794 Watts

100%eff = (12) x (230) x (1.0 (Power factor AC)) = 2760W
