<p class="p__0">As the rotor turns, the commutator picks different windings and the directional current is used to a given winding such that the rotor's electromagnetic field stays misaligned with the stator and creates a torque in one instructions. Drawbacks of commutator [modify] The commutator has drawbacks that has actually caused a decline in use of brushed motors.</p>

<p class="p__1">The soft brush material uses down due to friction, producing dust, and eventually the brushes need to be changed. This makes commutated motors inappropriate for low particle or sealed applications like difficult disk motors, and for applications that need maintenance-free operation. The electrical resistance of the sliding brush contact triggers a voltage drop in the motor circuit called brush drop which consumes energy.</p>

<p class="p__2">During the last a century, high-power DC brushed motors, as soon as the mainstay of market, were replaced by alternating current (AC) concurrent motors. Today, brushed motors are only used in low power applications or where just DC is readily available, but the above drawbacks restrict their usage even in these applications. Brushless service [edit] In brushless DC motors, an electronic servo system changes the mechanical commutator contacts.</p>
<br>
<p class="p__3">The removal of the moving contact allows brushless motors to have less friction and longer life; their working life is only restricted by the lifetime of their bearings. Brushed DC motors develop a maximum torque when fixed, linearly decreasing as velocity boosts. Some constraints of brushed motors can be conquered by brushless motors; they consist of greater performance and lower susceptibility to mechanical wear.</p>

<p class="p__4">A common brushless motor has permanent magnets that turn around a repaired armature, eliminating problems related to connecting present to the moving armature. An electronic controller changes the commutator assembly of the brushed DC motor, which continuously switches the stage to the windings to keep the motor turning. The controller carries out comparable timed power distribution by utilizing a solid-state circuit instead of 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, requiring no air flow inside the motor for cooling. This in turn indicates that the motor's internals can be totally enclosed and secured from dirt or other foreign matter.</p>
