Abstract
Various aspects of the present disclosure are directed to a transport device in the form of a planar motor. In one example embodiment, the transport device includes at least one transport segment forming a transport plane, at least one transport unit movable in the transport plane in at least two-dimensions associated with two main movement directions, and first and second coil groups. The first coil group defines the first main movement direction and has drive coils arranged on the at least one transport segment, and the second coil group defines the second main movement direction and has drive coils arranged on the at least one transport segment. The transport device further includes drive magnets arranged on the at least one transport unit and a control unit. The control unit controls the drive coils of the first coil group and the drive coils of the second coil group.
