WebJun 20, 2024 · Ans.3 The commutator is used to convert alternating current into pulsating direct current in an electric motor or DC generator. Q.4 How does the commutator convert ac to dc? Ans.4 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.

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. By reversing the current direction in the rotating windings each half turn, a steady rotating force ( torque) is … See more A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed … See more A commutator consists of a set of copper segments, fixed around the part of the circumference of the rotating machine, or the rotor, and a set of spring-loaded brushes fixed to the stationary frame of the machine. Two or more fixed brushes connect to the … See more The contact point where a brush touches the commutator is referred to as the commutating plane. To conduct sufficient current to or from … See more These are single-phase AC-only motors with higher starting torque than could be obtained with split-phase starting windings, before … See more 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 flow of current in a winding. For a single armature winding, when the shaft has … See more Early machines used brushes made from strands of copper wire to contact the surface of the commutator. However, these hard metal … See more Although direct current motors and dynamos once dominated industry, the disadvantages of the commutator have caused a decline in the use of commutated machines in the last century. These disadvantages are: • The … See more WebOct 6, 2024 · The generator is a device that produces electrical energy and motor produce mechanical power.
