    摘要： Statically pressurized gas bearings employ improved bearing pockets (20), each including one or more slots (21) arranged in a double cross, star or other configuration, and supplemental gas exhaust slots (74), as well as stepped annular land flow restrictors (28), to optimize bearing stability and operational bandwidth.

    摘要： An improved solid state commutated linear motor (18) with an ironless multiphase armature (20) is disclosed which has a magnetic field array (11) having periodic alternating polarity, an ironless multiphase armature, and a solid state commutating system for driving a moving element (34) and positioning it with respect to a reference element (32). In one embodiment, the magnetic field array is elongated and fixedly located with respect to the reference element, and the ironless multiphase armature is fixedly located with respect to the moving element. In a second embodiment, the ironless multiphase armature is elongated and fixedly located with respect to the reference element, and the magnetic field array is fixedly located with respect to the moving element. The magnetic field array is generated by an array of spaced alternate north and south poled magnets having an inter-pole distance L. The ironless multiphase armature is comprised of coils having a center-line span equal to the inter-pole distance L, wherein the coils are interleaved and staggered to form the various phases. Solid state switches (74 to 84) are used to commutate the phases by first faulting a phase as it approaches a space between magnetic poles and then reversing the connections of that phase as it leaves the space between the magnetic poles.
