Brushless ESC systems create three-phase AC power, like a variable frequency drive, to run brushless motors. Brushless motors are popular with radio-controlled aeroplane hobbyists because of their efficiency, strength, longevity and light weight compared to traditional brushed motors. Do brushless motors need ESC? Brushless ESC systems create three-phase AC power, like a variable frequency drive, to run brushless motors. Brushless motors are popular with radio-controlled aeroplane hobbyists because of their efficiency, strength, longevity and lightweight compared to traditional brushed motors. It is generally recommended that the ESC is more significant than double the current of the motor: like...
