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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …
