% EFF is motor efficiency per motor nameplate. Power factor is the ratio of true power (kW) to apparent power (kVA). In the absence of power factor measurement tools, a rule of thumb is to estimate power factor at 0.85. 1.73 is a constant used when calculating three-phase power. 746 is the constant for converting watts to horsepower (746 watts

For example, if a 100 hp motor has an unbalance factor of 3 percent, the motor should be derated to 0.88 or 88 percent of capacity, 88 hp. The frequent use of variable frequency drives (VFDs) can result in detrimental effects to electric motors because of the condition of power in manufacturing facilities.

The power factor of an induction motor is very low in the range of 0.1 to 0.3 when motor runs at no load.There are two components of the no load current- Magnetizing Current(Im) and Working Current(Iw) or no load loss component current.The motor takes magnetizing current for setting up the magnetic field in the air gap.

A high power factor allows efficient use of energy, while a low power factor indicates poor utilization of electrical power. Each equipment or load has its own power factor and depends on the resistive or inductive load, some typical or common values for buildings, appliances and motors are shown below.

Going one step further, Power Factor (PF) is the ratio of working power to apparent power, or the formula PF = kW / kVA. A high PF benefits both the customer and utility, while a low PF indicates poor utilization of electrical power. Here is an example. A steel stamping operation runs at 100 kW (Working Power) and the Apparent Power meter

Power Factor One often overlooked aspect of overall motor drive efficiency is the power factor. The power factor relates the shape of the current waveform drawn by a load to the sinusoidal voltage waveform supplied by the power company. If a load looks purely resistive, then the current drawn by the load is a sinusoid exactly in

Power Factor is an index used to measure the efficient use of electricity. This index is measured on a range of 0 to 1.0. For customers taking supply at 33 kV or below, the value of the power factor to be maintained is ≥ 0.85. Power factor < 0.85 will result in power factor surcharge.

PF= KW / KVA. Power factor is a way to find out how effectively you are using your electrical power. A high-power factor indicates effective utilization of electrical power, whereas low power factor signifies inefficient use of electrical power. The device is considered to be very efficient if the power factor is close to 1.

Starting an AC motor from a stop means very high starting current, but at a very low power factor. So the net energy cost is only a little higher that just running it. But starting from a stop does still consume more energy cost because you have to re-accelerate the mass without doing any useful work.
