What is the low power factor of AC motor in no-load operation?
First, if it is a single-phase motor, its power factor is equal to the three-phase, then it is low, in this case, the load is unbalanced
If it is an AC generator without no-load current, there will be no power factorIf AC motors were available, there could be two reasons
Second, the motor idling power down to the minimum (only to maintain its own idle torque), the motor internal inductive reactive little change, so that the active power to reduce the reactive power unchanged, power factors, of course, low
