ABSTRACT OF THE DISCLOSURE An electromagnetic servo unit is constituted with an outer casing (1), a first shaft (8) and a second shaft (5) both rotatably supported by the casing, an electric motor (101) built in the casing coaxially with the second shaft, the electric motor having an armature (10, 11) coaxially mounted on the second shaft, a torque detecting mechanism (8b, 22, 16, 21, 12) for detecting torque applied to either of the first and second shafts, and a control mechanism (21, 14, 15) for, receiving a detection signal from the torque detecting mechanism, controlling to start the electric motor. The torque detecting mechanism is arranged inside the casing, and the first and second shafts are mutually actuatably engaged with each other within the casing through the torque detecting mechanism. Preferably, the first and second shafts are coaxially supported by the casing, and have a relative angular displacement therebetween made use of for, when it is developed exceeding a predetermined angle range (.theta.), starting the electric motor. The first and second shafts are adapted to serve either as an input and the other as an output shaft.
