We talked about mechanical power and power curve. Variable frequency drives for adjusting motor speed are a good option, especially since many loads will experience large decreases in energy usage if the motor can be run at a slower speed.

Power Factor Is The Ratio Of True Power (Kw) To Apparent Power (Kva).
