What is the function of armature winding in dc machine?

Function of Armature The winding wound on the core is given current through a DC supply. This current-carrying winding as under the influence of the magnetic field develops a force that develops a rotational torque. This torque enables the machine to rotate.

What are the types of DC armature winding?

Types of Armature Winding:

Does a DC generator have an armature?

In a DC generator, the armature’s rotation is the process that generates a voltage in the rotor coils. The armature core includes iron slot laminations with slots that have been stacked to form a cylindrical armature core. Generally, the losses are decreased due to the eddy current in these laminations.

What type of armature are used in DC generators?

– Drum-type armature. Drum-type armatures are wound with either of two types of windings – the LAP WINDING or the WAVE WINDING. The lap winding is illustrated in figure 1-14, view a This type of winding is used in dc generators designed for high-current applications.

What is a armature winding?

Armature winding can be defined as, an electrical machine in which emf can be generated because of the air gap field flux. It must be noted that the air gap is produced because of the DC current flow in the winding. In general, this winding is housed on slots of the stator & the field winding on rotor slots.

Where is armature winding in DC generator?

The armature is the winding to which the load is connected. In small generators, the field windings are often on the stator, and the armature windings are on the rotor.

How many types of armature winding are there?

Types of Armature Winding. The winding of the machine is classified into two types. They are closed type winding and Open type winding.

What are the parts of armature?

Armature Components. An armature can be designed with the number of components namely the core, the winding, the commutator, & the shaft.

What is field and armature winding?

Armature Winding is the winding, in which voltage is induced. Field Winding is the winding in which the main field flux is produced when the current through the winding is passed.

What is armature winding made of?

The armature winding is made up of coils which are distributed around the inner periphery of the stator in equally spaced slots, so as to be linked by the flux produced by the field winding.

What are armature windings used for?

The first is to carry current across the field, thus creating shaft torque in a rotating machine or force in a linear machine. The second role is to generate an electromotive force (EMF). In the armature, an electromotive force is created by the relative motion of the armature and the field.
