Abstract:
It is provided an actuated machine having a main frame, a machine shaft mounted on the main frame by means of a bearing module, a gearless torque motor coupled to the machine shaft for driving a rotation of the machine shaft, a torque arm coupled to the gearless torque motor, and a catching structure. The gearless torque motor is coupled to the machine shaft 200 such that the gearless torque motor is capable of following a translational movement of the machine shaft. The torque arm is coupled to the gearless torque motor for inhibiting a rotational motion of the gearless torque motor, relative to the main frame, about a central axis of the gearless torque motor. The catching structure is arranged underneath the gearless torque motor for catching and holding the gearless torque motor in case of a failure causing the gearless torque motor's weight to be no longer carried by the machine shaft.
