Permanent magnet DC brushed motors (PMDC motors) consist of permanent magnets, located in the stator, and windings, located in the rotor.
The ends of the winding coils are connected to commutator segments, which have a sliding contact with the stationary brushes. Brushes are connected to DC voltage supply across motor terminals.
Change of direction of rotation can be achieved by reversal of voltage polarity.
The current flow through the coils creates magnetic poles in the rotor, that interact wthe permanent magnet poles
