Difference between Concentrated and Distributed winding


Electromagnetic armature winding creates magnetic poles, which can be concentrated as a single north and south pole in a concentrated winding configuration. However, in a distributed winding configuration, the armature has multiple north and south poles. Concentrated Winding According to concentrated winding, the coil turns are concentrated in one place. So no production of the … Read more

Armature core of a DC machine


In the case of DC generators – Mechanical Input is applied to the shaft/rotor (i.e, Armature) and Electrical output is collected from Armature itself. In the case of DC Motors – Electrical Input is applied at the Armature terminal and mechanical output at the rotor is received(i.e, Armature). Therefore armature is the center for electromechanical … Read more

Open coil winding and Closed coil winding of DC machine


Open coil winding and closed coil winding are the types of Armature windings. Armature windings are the non-salient pole type and usually are symmetrically distributed in the slots of the complete circumference of the armature. Basically two types of armature windings according to the degree of closure produced: Open Coil Winding: Open coil windings are … Read more
