A New Roller Conveyor Driven by Linear Motor

To solve technical problems of current roller conveyor, such as big volume, complex structure and heavy maintenance workload, a new roller conveyor has been researched by adopting advanced technology of three-phase A.C linear motor. It has no intermediate transmission units that exist in the conventional roller conveyor, and is a new form structure of the conveyor. The device consists mainly of rollers and linear motors. The roller serves as driving and load-bearing mechanism, and as the rotor of linear motor, too. In the process of operation, with rollers served as the carriers, the friction force between rollers and objects transmits the motion consummately to achieve the goal of transportation. This new conveyor can completely replace the current various types of roller conveyor with such features as simple structure, low failure rate and cost.
