ARMATURE
WINDING
In DC
machine, the drum type armature winding are used. It is usually a former wound
copper coil, which rest in armature slots. The armature conductor are
insulated.
THERE ARE
MAINLY TWO TYPES OF ARMATURE WINDING
1) Lap winding
2) Wave winding
1) LAP WINDING
In the lap winding,The coils is connected in series through the commutator segment in such a way that the armature winding is divided into as many parallel paths as the number of poles of the machine, i.e. In the lap winding number of parallel paths is equal to the number of poles.
“Lap
winding” is suitable for large machine which has high current and low voltage.
Two types of lap winding “simplex lap winding” and “duplex lap winding”
2) WAVE WINDING
In the case
of wave winding, The armature coil connected in series through the commutator
segment in such a way that the armature winding is divided into two parallel
paths irrespective of the number of poles.
“Wave winding” also known as “series winding”.
This type winding suitable for small machine, in which low current and high voltage.
