power factor and efficiency of large crusher motors

why crusher motors have poor power factor

Power factor is the relationship (phase) of current and voltage in AC electrical distribution systems. Under ideal conditions current and voltage are "in phase" and the power factor is "100 ." If inductive loads (motors) are present power factor less than 100 (typically 80 to 90 ) can occur. Get Price; Power Factor Correction Transformers Power

Motor Efficiency and Power Factor

Electric power consumption is rated power divided by motor efficiency. Rated power depends on class of motor (which considers intended duty). Industrial grade motors usually are rated for continuous duty. Motor efficiency requirements are set by 1992 Energy Policy Act (EPACT), primarily for larger motors as used in industry and HVAC.

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.
