  • Patent number: 8242732
    Abstract: An apparatus, system, and method are disclosed for stepper motor 102 stall detection. A conversion module 106 receives 1206 a back electromotive force (“EMF”) waveform 1002 produced in a non-driven coil of the stepper motor 102 by a magnetic field of a rotor of the stepper motor 102 during a full step operation 308, and samples 1208 the waveform 1002 at intervals starting at a predetermined time for a predetermined period of time within the full step operation 308 to yield a plurality of sampled data points. A rectification module 202 rectifies 1210 the waveform 1002 about a predetermined quiescent level 306. A comparison module 204 accumulates 1216 the rectified sampled data points into a statistically representative sampled value, compares the representative sampled value to a predetermined threshold level, and indicates 1224 a stall of the rotor if the representative sampled value is less than the predetermined threshold level.
