  • Publication number: 20260229978
    Abstract: Aspects of the present disclosure provide methods, devices, and systems for manufacturing and using a mover in a displacement system. The mover may include an impermeable outer surface or shell. A method of manufacturing a mover may involve joining a first shell portion to a second shell portion along at least one side face of the mover with at least one actuation magnet between the first shell portion and the second shell portion. The at least one side face may be between a first surface of the mover and a second surface of the mover opposite the first surface. The at least one actuation magnet may be configured to generate forces for moving the mover in response to at least one external magnetic field.

  • Patent number: 12627210
    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.
