sample question:
The name-plate of a 1-phase, 4-pole induction motor has the following data:
HP=0.5
Voltage=230 V
Frequency=60 Hz
FL current= 2.9A
power factor=0.71
rpm=1610
Calculate the current taken by the motor and it's power factor if a capacitor of 15.9 uF is connected across the motor while delivering the rated output as above.
The calculation used lagging power factor of the given current 2.9A above which I'm not so sure why. A motor doesn't necessary has lagging power factor, right?
