WebConstruction of a Commutator. A commutator is built with a set of contact bars and is set into the revolving shaft of a DC machine allied to the armature winding. The commutator reverses the current flow within a winding when the shaft turns. Once the shaft completes a half-turn, the windings are connected so that current supplies through it in ... WebMar 20, 2024 · In a brushed DC motor, the rotor spins 180-degrees when an electric current is run to the armature. To go any further, the poles of the electromagnet must flip. The brushes, as the rotor spins, make contact with the stator, flipping the magnetic field and allowing the rotor to spin a full 360-degrees.
