摘要:
A method for calibrating a positioner system that has an electronically commutated servomotor and a counterforce-loaded actuator coupled thereto includes actuating the servomotor such that a first motor magnetic field of a first strength is generated and determining a first position specification for the position of the actuator aligned to the first motor magnetic field. The servomotor is actuated such that a second motor magnetic field of a second strength is generated and a second position specification for the position of the actuator aligned to the second motor magnetic field is determined. Based on the first and the second position specifications, a position specification which indicates a position of the actuator under the assumption that the actuator is not loaded with a counterforce is determined. The determined position is allocated to a rotor position which corresponds to the direction of the first and second motor magnetic field.
