why coal mill motor low power factor design

3 safety measures for motors with individual power factor correction .Dec 6, 2017 . Several phenomena have to be considered in order to design an optimum protection and guarantee the safety of people and goods: . From a practical point of view, auto-excitation is most likely to occur when the motor power factor is relatively low, under 0.8, and installation power factor objective is high,.why coal mill motor low power factor design,Why is a 3 phase motor having low power factor considered as a bad .In the motor itself, low power factor also consumes the current carrying capacity of the windings. Winding capacity is finite, largely controlled . Since most of the extra losses are outside of the motor, the motor designer may not measure them, but they create a loss of efficiency in the power system. 361 Views · View Upvoters.
