Jul 11 2019nbsp018332The very basic construction of a DC motor contains a current carrying armature connected to the supply end through commutator segments and brushes. The armature is placed in between north pole and south pole of a permanent or an electromagnet as shown in the diagram above. As soon as we supply direct current in the armature a mechanical force acts on it due to the
