<p class="p__0">As the rotor rotates, the commutator selects various windings and the directional current is applied to a given winding such that the rotor's magnetic field stays misaligned with the stator and produces a torque in one direction. Downsides of commutator [modify] The commutator has downsides that has actually led to a decline in use of brushed motors.</p>
<br>
<p class="p__1">The soft brush material wears down due to friction, producing dust, and eventually the brushes need to be changed. This makes commutated motors unsuitable for low particulate or sealed applications like tough disk motors, and for applications that require maintenance-free operation. The electrical resistance of the moving brush contact causes a voltage drop in the motor circuit called brush drop which consumes energy.</p>

<p class="p__2">Throughout the last hundred years, high-power DC brushed motors, as soon as the pillar of industry, were replaced by alternating present (Air Conditioning) concurrent motors. Today, brushed motors are only used in low power applications or where just DC is readily available, however the above drawbacks limit their use even in these applications. Brushless service [edit] In brushless DC motors, an electronic servo system changes the mechanical commutator contacts.</p>

<p class="p__3">The elimination of the moving contact permits brushless motors to have less friction and longer life; their working life is only restricted by the life time of their bearings. Brushed DC motors establish an optimum torque when stationary, linearly decreasing as velocity increases. Some constraints of brushed motors can be overcome by brushless motors; they include higher performance and lower vulnerability to mechanical wear.</p>

<p class="p__4">A common brushless motor has permanent magnets that turn around a repaired armature, getting rid of problems associated with linking current to the moving armature. Key Reference replaces the commutator assembly of the brushed DC motor, which continually switches the phase to the windings to keep the motor turning. The controller carries out similar timed power distribution by using a solid-state circuit rather than the commutator system.</p>
<br>
<p class="p__5">With no windings on the rotor, they are not subjected to centrifugal forces, and since the windings are supported by the housing, they can be cooled by conduction, needing no air flow inside the motor for cooling. This in turn means that the motor's internals can be totally enclosed and secured from dirt or other contaminant.</p>
