Question

What is the function of the armature coil in the generator?

Answer 1

Hint: We need to mention the main function of armature. Also, it should be noted that armature consists of the core, winding, commutator and the shaft.

Complete step by step answer: An armature can be designed with the number of components namely the core, the winding, the commutator, & the shaft. The main role of an armature is multi purpose. The primary role is to transmit current across the field, therefore generating shaft torque within an active machine otherwise strength in a linear machine. The second role of an armature is to produce an EMF (electromotive force). In this, an EMF can occur with the armature’s relative motion as well as the field. As the machine is employed as a motor, then the EMF will oppose the current of an armature and convert the electric power into mechanical which is in the form of torque, and finally transmits through the shaft.
Whenever the machine is utilized like a generator, then the armature electromotive force drives the current of an armature, as well as the movement of the shaft will be changed to electrical power. In the generator, the power which is produced will be drawn from the stator. A growler is mainly used to ensure the armature intended for opens, grounds, as well as shorts.

Additional Information: An armature can be defined as a power generating component in an electric machine where the armature can be a rotating part otherwise a stationary part in the machine. The interaction of the armature with the magnetic flux can be done in the gap of air, the field element can include any stable magnets otherwise, electromagnets which are shaped with a conducting coil like another armature which is known as a doubly-fed electric machine. The armature always works like a conductor, sloping normal toward both the field as well as toward the motion direction, torque otherwise force.

Note: The armature rotation can be caused by the communication of two magnetic fields. One magnetic field can be generated by the field winding, whereas the second can be produced with the armature while voltage is applied toward the brushes to get in touch with the commutator. Whenever the current supplies through the winding of an armature, then it creates a magnetic field. This is out of line by the field created with the field coil. This will cause the power of attraction toward a single pole as well as revulsion from the other. When the commutator is connected to the shaft then it will also move with a similar degree as well as activates the pole. The armature will continue to chase the pole to spin.
