The power factor of an AC electric power system is defined as the ratio of the active (true or real) power to the apparent power. where. 1  Active (Real or True) Power is measured in watts (W) and is the power drawn by the electrical resistance of a system doing useful work.
Brushless DC electric motor (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors) are synchronous motors that are powered by a DC electric source via an integrated inverter /switching power supply, which produces an AC electric signal to drive the motor.
