  • Motor Efficiency and Power Factor - University of Alabama

    Power Factor Correction Electrical loss 2 between power plant and useful work output of motor was the transmission and transformer I2R and hysteresis losses resulting from the imaginary component of the power. This loss applies whenever an imaginary component is present- not just for motors. Power factor (PF) correction can reduce loss by

  • Power Factor and Efficiency of Induction Motors - Blogger

    The power factor in large fully loaded high speed motors can be as favorable as 90% for large high speed motors. At ¾ fullload, the largest high speed motor power factor can be 92%. The power factor for small low-speed motors can be as low as 50%. At starting, the power factor can be in the range of 10% to 25%, rising as the rotor achieves speed.

  • Determining Electric Motor Load and Efficiency

    Figure 2 Motor Power Factor (as a Function of % Full-Load Amperage) Overloaded motors can overheat and lose efficiency. Many motors are designed with a service factor that allows occasional overloading. Service factor is a multiplier that indicates how much a motor can be overloaded under ideal ambient conditions. For example, a 10-hp motor with a 1.15 service factor

  • Electric motor efficiency depends upon power factor – Part 1

    13/10/2009· 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 phase with the voltage waveform, and the power factor is unity. This is the most efficient

  • Power Factor verses Efficiency | Mike Holt's Forum

    04/04/2013· It is called POWER factor and not EFFICIENCY factor because it expresses the difference between the appearent or phantom power and the actual power that produces useable work. Power factor is inherent nature of a circuit element, and 'correcting' it will not produce 'more' work, it simply makes more phantom power available as useable power. It also helps to reduce voltage drop and it is a favored 'magical' power
