[Solved] A commutator in a DC generator is used to:
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.
