ABSTRACT:
An electromagnetic servo device (200) includes a driving control circuit (100), for an electric motor (20) for producing auxiliary torque to be applied to an output shaft (4). A control signal (Va) is provided to thereby supply an armature current (Io) of a controlled quantity, in a controlled direction of conduction thereof, in accordance with a detection signal (Vr, Vl) from a detection mechanism (13). The detection mechanism detects a phase difference (dP) between an input shaft (1) and the output shaft (4). The rotation speed (N) of the electric motor (20) is controlled with the control signal (Va), and is proportional to the quantity of the phase difference (dP).
