  • Publication number: 20260332015
    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.

  • Publication number: 20260291356
    Abstract: Aspects of the present disclosure provide a method of holding a cover to a stator of a displacement system. The stator includes a holding surface and at least one electrical conductor positioned to generate at least one magnetic field external to the stator and operable to move at least one mover in a working environment of the displacement system. The cover includes a first surface facing the holding surface of the stator and a second surface across the cover from the first surface. The method includes causing a first fluid pressure in at least a space between the holding surface of the stator and the first surface of the cover to be lower than a second fluid pressure at the second surface of the cover to urge the cover toward the holding surface to hold the cover to the stator.
