Construction of DC Machines - The Engineering Knowledge

01/01/2020  Construction of DC Machines. In the structure of DC machine either dc motor or generator, there are 2 main parts first one is the static or the second one is moving. The static part is stator and moving part is rotor. In stator of dc machine, there is a frame that provides protection and support to internal structure from external environment, in this frame, there are poles that produce field at the stator.

DC Generator : Construction, Working Principle,Types,

Construction. A DC generator is also used as a DC motor without changing its construction. Therefore, a DC motor otherwise a DC generator can be generally called a DC machine. The construction of a 4-pole DC generator is shown below. This generator comprises of several parts like yoke, poles pole shoes, field winding, an armature core, armature winding, commutator brushes.
