The DC Shunt-wound motor, running on Direct current, has its field windings placed in parallel to the armature In Electrical terms, parallel is generally denoted as shunt That is the reason behind naming it a DC Shunt motor Same voltage is applied to both shunt winding and armature in this motor This parallel configuration allows independent path of current for field winding and armature...

A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine Two or more electrical contacts called brushes made of a soft conductive material ....

There is no basic difference in the construction of a DC generator and a DC motor In fact, the same DC machine can be used interchangeably as a generator or as a motor Like generators, there are different types of DC motors which are also classified into shunt-wound, series-wound and compound-wound dc ,...
