Abstract
A motor drive circuit provides a drive signal to an electronically commutated motor. A control circuit the motor drive circuit based on calibration data. The calibration data indicate a relationship between an actual angular position of a rotor of the motor in response to the drive signal and an expected angular position of a rotor of an ideal motor in response to the drive signal.
