Armature Winding and Field Winding – Difference between Armature and Field


Winding can be classified in two types: armature
winding and field winding. The armature winding is the main current-carrying
winding in which the electromotive force or counter-emf of rotation is induced. The current in the armature winding is known
as the armature current. The field winding produces the magnetic field
in the machine. The current in the field winding is known
as the field or exciting current. In this video I will go to show you Difference
between armature winding and field winding. An armature winding is the power-producing
component of an electric machine. The armature can be either on the rotor or
the stator of the electric machine. In the armature, an electromotive force is
created by the relative motion of the armature and the field. When the machine is used as a motor, this
EMF opposes the armature current, and the armature converts electrical power to mechanical
power in the form of torque, and transfers it via the shaft. When the machine is used as a generator, the
armature EMF drives the armature current, and the shaft’s movement is converted to electrical
power. A field coil is an electromagnet used to generate
a magnetic field in an electro-magnetic machine, typically a rotating electrical machine such
as a motor or generator. It consists of a coil of wire through which
a current flows. In a rotating machine, the field coils are
wound on an iron magnetic core which guides the magnetic field lines. The magnetic core is in two parts; a stator
which is stationary, and a rotor, which rotates with it. The magnetic field lines pass in a continuous
loop or magnetic circuit from the stator through the rotor and back through the stator again. The field coils may be on the stator or on
the rotor. Dear viewers Thanks for watching the video,
