A brushless DC electric motor, or BLDC, also known as an electronically commutated motor, is a synchronous motor powered by a direct current electric supply. It uses an electronic controller to switch DC currents to the motor windings, producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows, and the controller adjusts the phase and amplitude of the current pulses to control the motor speed and torque. It is an improvement on the mechanical commutator, or brush, arrangement used in many conventional electric motors, replacing physical contact switching with electronic switching.
