What are the Essential Part of DC Machine Explanation
WebThe armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors. The armature can be on either the rotor (rotating part) or the stator (stationary part), depending on the type of electric machine. WebOct 22, 2024 · The commutator is a mechanical switch that, at an appropriate point in the rotation of the coil, sends current through the coil in the appropriate direction.
