Construction and Principle of Operation of the Shunt DC Motor

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.
