power factor and efficiency of large crusher motors

Understanding Power Factor And Harmonics Oct 14 2015The powerfactor angle is zero and the power factor bees unity For purely inductive or capacitive loads real power reduces to zero and the power factor falls to zero also In the case of a real inductive load like a motor the voltage leads the current increasing the powerfactor angle to yield a displacement power factor of less than one
