Principle of operation A commutator consists of a set of contact bars fixed to the rotating shaft of a machine, and connected to the armature windings. As the shaft rotates, the commutator reverses the …

Now in order that the r and p factors have the same indices in each term, so that they may be factored, we will rename s to q, q to j and k to s in the second term only:

Oct 9, 2025 · Explore the structure and function of the commutator, the essential mechanical component for current handling in DC motors and generators.

Jul 23, 2025 · A commutator is an electrical component found in electric motors, generators, and dynamometers. Its primary function is to reverse the direction of current flow in the windings of the …

3 days ago · commutator (plural commutators) An electrical switch, in a generator or motor, that periodically reverses the direction of an electric current.

The commutator in a generator takes up the current created in the windings and acts as a mechanical rectifier by reversing the current's direction with each half turn.

A commutator is a rotary electrical switch that periodically reverses the current between the rotor and the external circuit. The commutator was discovered by William Ritchie and Hippolyte Pixii in 1832.
