A DC motor apparatus includes a motor housing assembly which includes an outer liquid-tight coolant chamber and an inner, armature-reception chamber portion. Pairs of permanent magnet stator magnet modules are housed within the liquid-tight coolant chamber, and shunt members are housed within the liquid-tight coolant chamber between the stator magnet modules. An armature is centrally located in the inner, armature-reception chamber portion. The armature includes at least one pair of armature pole portions which are wound with same-directional windings. A commutator is connected to the armature, and the commutator includes commutator contacts. An adjustable brush advance/retard mechanism includes roller brushes for contacting the commutator contacts. A liquid cooling system includes a coolant pump and a coolant fluid radiator for circulating liquid coolant through the liquid-tight coolant chamber for cooling the stator magnet modules and the shunt members.
