Abstract: A permanent magnet rotor assembly includes a cylindrically shaped shaft having an outer surface, a plurality of permanent magnets constituting portions of annular segments and an outer retaining cylindrical sleeve surrounding the plurality of permanent magnets. The assembly further includes a cylindrical magnet housing mounted on the cylindrically shaped shaft for supporting the plurality of permanent magnets. The cylindrical magnet housing is formed of a magnetic material. The retaining cylindrical sleeve is preloaded by a resultant interference fit IF2 defined by the following formula IF2=−ØY+√{square root over (((ØY+IF1)^2+ØY^2−ØX^2))}, where ΦY is an external diameter of the plurality of permanent magnets, ΦX is an internal diameter of the cylindrical magnet housing, and IF1 is a primary interference fit between an external diameter of the cylindrically shaped shaft and the internal diameter of the cylindrical magnet housing.

Abstract: A vacuum pump including a pump main unit and a control unit is disclosed. The control unit includes a substrate having electronic elements mounted thereon and terminal pins soldered to the substrate at a first end edge of the substrate. The substrate is mounted to a plate via an attachment near a second end edge opposing the first end edge and the plate is mounted to the pump main unit. The terminal pins extend through the plate. Upon linear thermal expansion of the terminal pins, by reason of the location of the terminal pins near the first end edge and the attachment near the second end edge, stresses in the soldered pin connections are reduced. A molding material having a Shore hardness of less than 50, is molded around the electronic elements on the substrate in one embodiment.

Abstract: A stator assembly that provides a concentric housing and stator, the stator radially positioned inside the housing, the housing having an inner surface, the stator having an outer surface radially facing the inner surface. One of the outer surface of the stator and the inner surface of the housing has recessed shapes and the other one of the outer and inner surface has protruding shapes. When the two shapes are arranged in a first relative position, the protruding shapes are inserted in the recessed shapes so that the stator can be mounted radially inside the housing along a central axis of the assembly, and in a second relative position that is angularly shifted relative to the first position around the central axis, the protruding shapes exert, against the one of the housing and the stator that bears the recessed shapes, a radial force that angularly and axially locks the stator.

Abstract: A vacuum pump having substrates which can be wired together easily and cooled easily. A substrate unit structure is formed by covering the opening of the casing of the pump main unit with a plate functioning also as the casing of the control unit. Pins of a terminal fixed while penetrating the plate are soldered directly to an active magnetic bearing (AMB) control substrate and an aerial connection substrate in order to integrate these components. The casing and sealing structures can be of simple construction. A drip-proof structure can be made with the terminal at low cost without using expensive drip-proof connectors. Further, by cooling the plate, electronic components mounted respectively on the AMB control substrate in a vacuum atmosphere and the aerial connection substrate in an air atmosphere can be cooled simultaneously.

Abstract: To be provided is a vacuum pump having substrates which can be wired together easily and cooled easily.A substrate unit structure is formed by covering the opening of the casing of the pump main unit 100 with the plate 201 functioning also as the casing of the control unit 200. Pins 207 of a terminal 210 fixed while penetrating the plate 201 are soldered directly to an AMB control substrate 209 and an aerial connection substrate 211 in order to integrate these components. Therefore, the casing and sealing structures can be made simple. Accordingly, a drip-proof structure can be made with the terminal 210 at low cost without using expensive drip-proof connectors 1 and 3. Further, by cooling the plate 201, electronic components mounted respectively on the AMB control substrate 209 in a vacuum atmosphere and the aerial connection substrate 211 in an air atmosphere can be cooled simultaneously.
