Abstract: The invention provides an assembly having a cryostat and a flat coil layer of superconducting coils for use with a magnetic levitation and/or acceleration motor system of a lithographic apparatus. The cryostat has two insulation coverings. The coil layer is arranged between the two coverings. The coverings each have an inner plate configured to be cryocooled and an outer plate parallel to the inner plate, and an insulation system with a vacuum layer between the inner and outer plate. The insulation system of said covering has a layers of circular bodies, the central axes of these bodies extending perpendicular to the inner and outer plate, and is configured to provide a layer of point contacts between two layers of circular bodies or between a layer of circular bodies and the inner and/or outer plate.

Abstract: A stator for an electric machine includes a stator core with a multi-phase winding arranged on the stator core. The stator core has a plurality of slots formed therein and defines a first axial end and a second axial end. The multi-phase winding includes multiple parallel paths for each winding phase, each parallel path completing multiple revolutions around the stator core, and each parallel path comprising a series of slot segments arranged in layers of the plurality of slots and end turns alternately connecting consecutive slot segments on the first axial end and the second axial end. A pitch of the end turns connecting the slot segments for at least one parallel path alternates between a first pitch on the first axial end and a second pitch on the second axial end, the second pitch being different from the first pitch.

Abstract: A single phase induction motor includes a stator core having a stator yoke and a plurality of teeth extending toward a central opening. The plurality of teeth are spaced apart from one another and define multiple slots between the teeth for receiving windings of the single phase induction motor. The stator core includes a high permeability low coreloss (HPLC) steel having a relative permeability of greater than or equal to 3000 at 1.5 Tesla and 60 Hertz, and a coreloss of less than or equal to 1.75 watts/lb at 1.5 Tesla and 60 Hertz. The motor also includes multiple windings located within the plurality of slots and wrapped around the plurality of teeth of the stator core. Each of the multiple windings include aluminum wire.
