Brush less DC motor Seminar abstract
Brush less DC motors (Electronically commutated motors - ECMs) are synchronous motors which are powered by a DC electric source via an integrated inverter, which produces an AC electric signal to drive the motor. Additional sensors and electronics control the inverter output.
