Stators, stator devices, and attachment of cover to stator for displacement systems

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.

Dependencies are inferred from the claim text.
