Patent ID: 8217601

Claim:
A device for aligning a relative position feedback device to a motor rotor, wherein a rotatable input of the relative position feedback device is coupled to the motor rotor so as to rotate therewith, the relative position feedback device having at least one marker indicative of a location of the rotatable input within one electrical cycle of the relative position feedback device, comprising: a processor and memory operatively coupled to the processor; and logic stored in the memory and executable by the processor so as to cause the processor to: rotate the motor rotor a distance corresponding to a non-zero offset angular distance, plus a predetermined angular distance corresponding to one electrical cycle of the relative position feedback device; while the motor rotor is rotating, initialize a counter upon detection of the at least one marker; command the motor rotor to at least one predetermined angular location; obtain data stored in the counter at the at least one predetermined angular location; and based on the obtained data, determine a location of the motor rotor relative to the at least one marker.
