While developed to replace brushed DC motors, DC brushless motors are smaller than their predecessors or AC counterparts and include pancake and cylindrical constructions. Without a commutator or slip ring, these motors require an alternating current or direct channel via an embedded controller (EC). These brushless electronic motors are permanent-magnet synchronous, relying upon electronic mechanisms for current creation and control, creating motion when the current stimulates stator and the rotor's in-built magnets follow.
DC brushless motors tend to have greater efficiency, longer lifespans, and fewer maintenance issues; such long-term benefits far outweigh these motors' initially higher cost. DC brushless motors have become essential for computer and commuter applications, from hard disk drives to electric vehicles.
