How a commutator works
WebCommutator. A commutator works like a rectifier that changes AC voltage to DC voltage within the armature winding. It is designed with a copper segment, and each copper segment is protected from the other with the … Web24 de mar. de 2024 · These motors work by means of the mechanical linkage between their commutator and brushes. The brushes and commutator are in continual contact as the motor rotates. This causes wear of the motors by long-term use that can ultimately result in motor failure. For this reason, brushed DC motors have a shorter life than brushless DC …
