Abstract
In a method for operating an EC motor, position-measurement signals are recorded by a position-measuring device, and, on the basis of the position-measurement signals, commutation instants are determined, at which the current supply to the EC motor is commutated. At least one correction value for at least one position-measurement error contained in the position-measurement signals is ascertained and stored. To compensate for the at least one position-measurement error, the correction value is considered when determining the commutation instants.
