BOPI 08 BR/2024 REPERTOIRE NUMERIQUE 28 (73) HAKA GROUPS PARTICIPAÇOES DE NEGÓCIOS S/A, Avenida Raja Gabaglia, 3502, Sala 201, Andar 2, 30494310 BELO HORIZONTE (BR) (74) S.C.P. AKKUM AKKUM & Associates, No. 1777, Rue 6.261, Auditorium Jean Paul II, Quartier Mbankolo, B.P. 4966, YAOUNDE (CM). (57) This invention describes a conveyor belt driven by linear motors distributed along the belt, rather than at the head thereof. These linear electric motors or of the induction type with a short primary having two action sides and a long secondary made of plates of conducting material, such as aluminium or copper. The secondary plates are vertically fixed in the central portion of the rubber belt or metal belts. The invention was developed to simplify the operation and maintenance of conveyor belts, since the present equipments require a very high mechanical tension. Such tension causes rubber stretching, friction between the movable parts, wear of the rolling elements and lack of energy efficiency. The proposal of distributing the linear motors increases the reliability and availability of the equipment since, in the event of failure of any of the motors, operation need not be stopped for maintenance, as the load can be redistributed to the other linear motor units in operation. The invention is used with conveyors having rubber belts, metal conveyors (also known commercially as plate conveyors, pan conveyors or apron feeders), and with vertical conveyors, also known as bucket conveyors or elevators.
