Abstract: A transport device can be moved over a floor in order to transport at least one object and/or one person by means of at least one rolling device (3). A drive element (4) can be rotated at least indirectly using the rolling device (3). The drive element (4) comprises at least two drive magnets (12). An output element (7) is provided which has at least two output magnets (15). The number of drive magnets (12) differs from the number of output magnets (15). At least one non-magnetic shielding element (5) is provided in order to change the orientation of a magnetic field located between the chive element (4) and the output element (7). The output element (7) can be rotated. At least one stator winding (8) is arranged in which the output element (7) can be rotated about an axis of rotation (11) in order to generate electric current.
