Encoderless Motor With Improved Granularity And Methods Of Use
Abstract: 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 relative the substrate to be determined from linear portions of the sinusoidal signal without requiring use of an encoder or position sensors and without requiring noise reduction or filtering of the signal.
