摘要： A phase detecting actuator for a steering system having a rotatable steering shaft and a rotatable output shaft coupled to the steering shaft so that the output shaft is rotatable relative to the steering shaft includes a cylindrical magnet attached to and rotatable with one of the steering shaft and the output shaft of the steering system. An electromagnetic system includes a magnetic coil and first and second cylindrical poles having opposite polarities and communicating with the magnetic coil, the first and second poles attached to and rotatable with the other of the steering shaft and the output shaft of the steering system. The magnetic coil generates an input signal corresponding to magnetic flux generated by the relative rotation between the cylindrical magnet and the first and second poles, and a control unit receives the input signal from the magnetic coil and generates an output signal to energize the magnetic coil to create a magnetic positioning force between the cylindrical magnet and the first and second poles to position the output shaft relative to the steering shaft.
