  1. 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. In this context, AC, alternating current, does not imply a sinusoidal waveform, but rather a bi-directional current with no restriction on the waveform. Additional sensors and electronics control the inverter output amplitude and waveform (and therefore, percent of DC bus usage/efficiency) and frequency (i.e. rotor speed).
