Abstract: 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.
