A mechanically-commutated DC motor has a mechanical commutation system and an “inside-out” configuration, in which the stator assembly comprises the windings and the rotor assembly comprises the permanent magnet. The motor includes a rotor assembly, a stator assembly, a plurality of terminating conductive pads, and positive and negative stationary power supply terminals. The stator assembly includes a plurality of lamination stacks positioned around a central aperture and a plurality of copper coils, each coil being wound around one of the lamination stacks. The rotor assembly includes a rotor body with a permanent magnet ring and a non-conductive timing cam integrated into one face of the rotor body. The permanent magnet ring is radially magnetized in an alternating polarity pattern with at least one pair of poles. The mechanical commutation system comprises the timing cam integrated into the rotor assembly, the power supply terminals, and the conductive pads. There are the same number of conductive pads as stator coils. Each conductive pad has first and second flexible contacts selectively movable into and out of electrical contact with the positive and negative power supply terminals, respectively, in response to the action of the timing cam. Adjacent ends of adjacent coils terminate on a common conductive pad, so that the ends of each coil terminate on two different conductive pads, and each conductive pad receives the ends of two different coils.
