Why does an Induction Motor has Poor Power Factor at …
The power factor of an induction motor is very low, in the range of 0.1 to 0.3 when the motor runs at no load. There are two components of the no-load current- Magnetizing Current(Im) and Working Current(I w) or no-load loss component current.The motor takes magnetizing current for setting up the magnetic field in the air gap.

What is Power Factor and why is it important?
Power factor is defined as the ratio of Active Power (kW) to Apparent Power (kVA). P.F = Active Power(kW) / Apparent Power (kVA); Also, the Power factor is the cosine of the phase angle difference between voltage and current pharos. P.F = Cos θ, Where θ is the angle between V and I.; One more way of defining the Power Factor is that it is the ratio between the resistance (R) …

A motor's power factor represents the ratio of active or real power (RP) to the apparent power (AP), which is the product of voltage and current. A low power factor indicates that the motor is drawing more RP and less active power, which can lead to voltage drops, overheating, and energy waste. In contrast, a high power factor suggests that the ...
