A DC electric motor having a stator mounted to a substrate, the stator having a coil assembly having a magnetic core, a rotor mounted to the stator with permanent magnets distributed radially about the rotor, the permanent magnets extending beyond the magnetic core, and sensors mounted to the substrate adjacent the permanent magnets. During operation of the motor passage of the permanent magnets over the sensors produces a substantially sinusoidal signal of varying voltage substantially without noise and/or saturation, allowing an angular position of the rotor to be determined from the sinusoidal signals by utilizing a transformation matrix or piece-wise algorithm applied in substantially linear portions of the sinusoidal signals without requiring use of additional hardware encoder or position sensors and without requiring noise-reduction or filtering of the signal.
