What is the plex of an armature winding?
Differentiate the two types of armature windings in DC machines: lap winding
and wave winding.
In DC machine winding, number of
commutator segments is equal to
number of armature coil sides
) number of armature coils
) number of armature conductors
) number of armature turns
