摘要： 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.

摘要： 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.

摘要： To be provided is a vacuum pump reducing the influence of thermal expansion of connector pins to prevent cracks in soldered parts while preventing damage to electronic elements.Pins 207 linearly expand with the heat accumulated in a bottom space 301. The bottom space 301 is heated quite easily since it is in a vacuum environment. A screw 235A is arranged near the left edge of an AMB control substrate 209. Since no screw is arranged on the right of the screw 235A, the AMB control substrate 209 is released toward the right. When the pins 207 expand with heat, the AMB control substrate 209 bends by an angle θ2 from the screw 235A as a fulcrum, but this bend angle is gradual, which means that the possibility of causing cracks in solder connection parts between the AMB control substrate 209 and the pins 207 is extremely small. Since deforming pressure of the AMB control substrate 209 is reduced, influence on the electronic elements can be reduced correspondingly.
摘要翻译：要提供的是减少连接器针的热膨胀影响的真空泵，以防止焊接部件中的裂纹，同时防止损坏电子元件。引脚207随着积聚在底部空间301中的热量线性地膨胀。底部空间301由于处于真空环境而被非常容易地加热。螺钉235A布置在AMB控制基板209的左边缘附近。由于在螺钉235A的右侧没有设置螺钉，所以AMB控制基板209向右释放。当引脚207随着热量膨胀时，AMB控制基板209以螺钉235A的角度θ2作为支点弯曲，但该弯曲角度是逐渐的，这意味着在AMB控制基板 209和引脚207非常小。由于AMB控制基板209的变形压力减小，所以对电子元件的影响可以相应地降低。

摘要： The axially adjustable magnetic bearing comprises an annular body secured to a support, a magnetic bearing stator structure having an annular sheath for supporting electromagnet windings placed concentrically relative to said body, and an annular rotor armature placed concentrically relative to the stator structure, leaving an airgap relative thereto. The annular body includes at least one radial slot associated with clamping means, and includes a set-back portion in its face facing towards the stator structure. The face of the annular body facing towards the stator structure includes a sliding surface that co-operates with a facing portion of said sheath, and the set-back portion of the annular body presents a threaded portion that co-operates with a threaded portion of an adjustment ring engaged in an annular groove formed in the face of the sheath that faces towards the body. The adjustment ring is prevented from moving in the axial direction in said annular groove.

摘要： A rotor sensor target for magnetic bearings, the rotor sensor target comprising a ring-shaped assembly of magnetic material mounted on a generally ring-shaped assembly of non-magnetic material. The magnetic and non-magnetic ring shaped assemblies are coaxially arranged and mounted on a shaft having a longitudinal axis of rotation X′-X. The generally ring-shaped assembly of non-magnetic material comprises at least one ring-shaped slit having the longitudinal axis X′-X and may be made of a cheaper material, such as aluminum. The ring-shaped slit provides flexibility which permits operation over a wide range of temperatures without risking of damaging the ring-shaped assembly of magnetic material.
