Abstract:
A motor calibration system and method for a motor having a rotor and a stator and comprising at least one phase. The system further comprises at least one position detector adapted to detect a position of the rotor with respect to the stator and generate a feedback signal and a controller adapted to perform a calibration sequence to calibrate to motor. Wherein the controller calibrates the motor by driving at least one motor phase with a motor control signal at a predetermined maximum amplitude value in a first direction with substantially no load applied on the motor, receiving a feedback signal from the at least one position detector, and determining a first calibration angle shift by measuring a difference between at least the motor control signal and the feedback signal of the at least one motor phase. The controller accounts for the first calibration angle shift when driving the motor in the first direction during normal operation. According to one embodiment, the controller may determine a second calibration angle shift for a second direction in a similar manner. According to another embodiment, the may determine the second calibration angle shift using a transformation function and a predetermined angle shift sum constant.

Claim (Index 31):
The motor control system of  claim 25 , wherein to determine the first calibration angle shift, the controller is adapted to:\n determine a plurality of angle shift sample values from at least the motor control signal and the feedback signal; and average the plurality of angle shift sample values to determine the first calibration angle shift.
