Which is commutator in dc motor? Explained by FAQ Blog Commutator (electric) - Wikipedia What Is Difference Between Slip Ring And Commutator? A split-ring device known as a commutator reverses the current at that point to keep the torque on a DC motor from reversing whenever the coil moves through the plane perpendicular to the magnetic field. This interacts with the magnetic filed across the main poles causing the loop to rotate to align its magnetic fi. This reverse in current causes the forces acting on the coil to be reversed. a split ring commutator. Q. A commutator itself is a split rotary ring, typically made of copper, with each segment of the ring attached to each end of the armature coil that is used in some types of electric motors and electrical generators whose job is to periodically reverse the current direction between the rotor and the external circuit. Split rings = for DC current (reverses the current every half turn, to change the dir.
