Commutators are used in direct current (DC) machines: dynamos (DC generators) and many DC motors as well as universal motors. In a motor the commutator applies electric current to the windings.

Jul 23, 2025 · In a DC motor or generator, the commutator consists of a series of copper segments attached to the ends of the armature coils. These segments are insulated from each other and …

Jan 7, 2016 · The voltage generated in the armature is alternating in nature, and the commutator converts it to direct current. Simply put, the commutator turns the coils on and off to control which …

To keep the torque on a DC motor from reversing every time the coil moves through the plane perpendicular to the magnetic field, a split-ring device called a commutator is used to reverse the …

In a DC machine, each armature coil contains two commutators attached to its end. The commutator segments and brushes should maintain a continuous moving contact for the better transformation of …

A commutator is a mechanical part found in many DC (direct current) motors. It rotates with the motor shaft and works with carbon brushes to control the flow of electricity into the motor windings.

Mar 20, 2013 · The commutator of a DC motor is a cylindrical structure made of copper segments, insulated by mica. Its main function is to relay the supply current from the mains to the armature …

Commutator consists of number of segments or bars insulated from each other and are combined together tightly to form a cylinder as shown in figure (1), and fitted on the insulated shaft of the …

Aug 25, 2025 · In conclusion, the commutator is a critical component of a brushed DC motor. Its primary function of reversing the current in the rotor coils enables continuous rotation, controls torque and …

Oct 26, 2023 · Direct Current (DC) Motors: In DC motors, the commutator is an integral part, as it helps to switch the direction of the current, thereby ensuring that the motor rotates continuously. It serves …
