ABSTRACT:
A transporting device of the conveyor belt type, in which a transporting belt, on which the material to be transported can be supported, is capable of being moved along a transport path by a driving mechanism and carried using rolling bodies. The transport path is equipped with an electrical travelling-wave stator (10). Permanent magnets (16) are provided arranged in series, which communicate with the transporting belt (20) in a power-transmitting fashion and form a linear motor with the travelling-wave stator (10) with an air-gap between the pole faces of the attracting permanent magnets (16) and the travelling-wave stator (10). The permanent magnets (16) and the travelling-wave stator (10) are held at air-gap space (a) by rolling bodies (14).
