Brushless Permanent Magnet Motor. Also known as BLDC Motors. These Motors require special BLDC Controllers. A BLDC motor has permanent magnets which rotate and a fixed armature, eliminating the
problems of connecting current to the moving armature. An electronic
controller replaces the brush/commutator assembly of the brushed DC
motor, which continually switches the phase to the windings to keep the
motor turning. The controller performs similar timed power distribution
by using a solid-state circuit rather than the brush/commutator system.
