Difference between Armature and Commutator
2022-05-26
The combination of the commutator, ball bearings, winding & brushes is called an armature. It is an essential part where all these parts include here to execute different tasks. It is responsible for the flux generation once the current supply throughout the winding is connected through the field flux.
This flux association generates a reaction that locates some influence on the flux caused. The flux obtained will get decreased or distorted because of the armature reaction. However, the commutator role is dissimilar from the armature because it is utilized for unidirectional energy generation.
What is an Armature?
In electrical machines like motors and generators, the armature is an essential component that holds AC or alternating current. In a machine, it is a stationary part or rotating part. The interaction of armature through the magnetic flux can be attained within the air gap.
As a conductor, an armature works & normally sloping within both the field directions & the direction of torque, motion, or force. The essential components of an armature mainly include the core, the shaft, the commutator, and the winding.
Armature Components. An armature can be designed with a number of components namely the core, the winding, the commutator, & the shaft.
An armature is used for different purposes. The main function of this is to transmit current across the field & produces shaft torque in an active machine or linear machine. The secondary task of this is to generate an electromotive force (EMF).
In this, both the relative movement of the armature & the field can be an electromotive force. When the machine is utilized like a motor, then EMF will oppose the current of an armature & it converts the power from electrical to mechanical in a torque form. Finally, it transmits it throughout the shaft.
Once the mechanism is used as a generator, then the EMF of the armature will drive the current of the armature & the motion is changed to electrical power. In the generator, the generated power will be drawn from the stationary part like the stator.
What is Commutator?
A rotating electrical switch like a commutator has periodically overturned the flow of current among the rotor & the exterior circuit. A commutator includes a set of copper segments that are arranged approximately to the part of the turning machine otherwise the rotor & a set of brushes loaded with spring can be attached to the inactive frame of the DC machine.In DC machines like DC motors and generators, commutators are used. A commutator provides a current supply to the motor windings. A stable rotary torque can be generated by overturning the direction of current within the rotary windings every half turn.

The commutator in a generator will reverse the flow of current direction through every turn serving as a mechanical rectifier to change the AC from the generator windings to unidirectional DC within the exterior load circuit.
The applications of armature include the following.
