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.
