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.

Abstract: A system and a method are disclosed for monitoring a condition of a conveyor belt arranged to rotate about at least a motor drive pulley and an idler pulley. A sensor unit can determine at least one sensor signal representing at least one operating variable of the electrical motor. A data processing unit can derive from the sensor signal at least one corresponding time dependent data signal, to detect irregularities in the data signal which indicate that a splice region of the conveyor belt passes the drive pulley and/or the idler pulley, to determine from a change in shape or in frequency of the irregularities, whether the condition of the conveyor belt has changed, and to send a signal which reflects a change in the condition of the conveyor belt to at least one of a display unit, a storage unit and/or a decision making unit.

Abstract: A motor drive for a gearless belt conveyor drive system, which includes a motor base frame, a torque arm mounted on the motor base frame or a conveyor baseplate, a rotationally symmetrical stator of a synchronous motor being fixedly held by the torque arm and a rotationally symmetrical rotor casing containing permanent magnet elements of the rotor of the synchronous motor. The rotor casing is directly mountable on a front end of a cylindrical belt conveyor pulley so that the permanent magnet elements of the rotor rotate around the stator and so that the symmetry axis of the rotor casing and the symmetry axis of the stator are aligned with each other and with a longitudinal axis of the belt conveyor pulley.

Abstract: A process for welding explosive-clad metal sheets together with one another and/or with metal pipes, connecting elements, or the like, includes producing at least one unjoined zone between the base metal and the cladding metal in a defined manner during an explosive cladding step, and thereafter welding in the region of at least one of unjoined zones.
