<p>A motor drive for a gearless belt conveyor drive system comprises a motor base frame (9), a torque arm (8) mounted on the motor base frame (9), a rotationally symmetrical stator (7, 14) of a synchronous motor being fixedly held by the torque arm (8) and a rotationally symmetrical rotor casing (4) containing permanent magnet elements (6) of the rotor of the synchronous motor. The rotor casing (4) is directly mountable on a front end of a cylindrical belt conveyor pulley (1) so that the permanent magnet elements (6) of the rotor are rotary around the stator (7) and so that the symmetry axis of the rotor casing (4) and the symmetry axis of the stator are aligned with each other and with the longitudinal axis (16) of the belt conveyor pulley (1). This motor drive belongs to a gearless belt conveyor drive system, which further comprises a cylindrical belt conveyor pulley (1) mounted so as to be rotary around its longitudinal axis (16), and at least one flange (3, 13) for fixedly connecting the belt conveyor pulley and the rotor casing (4) of the motor drive.</p> |
