Abstract: Displacement devices comprise a stator and a moveable stage. The stator comprises a plurality of coils shaped to provide pluralities of generally linearly elongated coil traces in one or more layers. Layers of coils may overlap in the Z-direction. The moveable stage comprises a plurality of magnet arrays. Each magnet array may comprise a plurality of magnetization segments generally linearly elongated in a corresponding direction. Each magnetization segment has a magnetization direction generally orthogonal to the direction in which it is elongated and at least two of the magnetization directions are different from one another. One or more amplifiers may be connected to selectively drive current in the coil traces and to thereby effect relative movement between the stator and the moveable stage.

Abstract: In order to at least temporarily increase the throughput of transported objects in a transport device in the form of a planar motor, without negatively influencing the movement of the transport units, at least one engagement portion is provided on each of the at least two transport units, it being possible for the at least two transport units to be moved in succession in the transport plane in a direction of movement into an engagement position in which the engagement portions of the transport units are at least partially engaged. The engagement portions are designed to overlap with one another in the engagement position at least in the direction of movement such that a total extent of the transport units in the direction of movement is smaller than a sum of the individual transport-unit extents of the transport in the direction of movement.
