摘要： This invention relates to a piston and a method of manufacturing the same. The piston includes a substantially cylindrical member having a first end and a second end. The cylindrical member includes an open cavity extending axially from the second end to adjacent the first end such that the second end has an inner annular surface defined by an inner diameter. The piston further includes a disk having a radially outer surface defined by an outer diameter fixedly secured to the second end of the cylindrical member. The outer diameter of the disk is substantially equal to the inner diameter of the inner annular surface of the second end of the cylindrical member. A circumferentially extending recessed area for receiving particles produced while fixedly securing the disk to the second end of the cylindrical member is provided on either the radially outer surface of the disk or the inner annular surface of the second end of the cylindrical member.

摘要： A magnetic bearing (10) is provided for supporting a rotor (12) for rotation about an axis (14). The magnetic bearing (10) includes a plurality of actuator cores (16) spaced circumferentially about the axis (14), and a plurality of non-magnetic spacers (18A, 18B). Each of the cores (16) has a pair of circumferentially spaced end surfaces (28). Each of the spacers (18A, 18B) is positioned between the end surfaces (28) of adjacent pairs of the cores (16) and has an interference fit with the end surfaces (28) to form a circumferentially preloaded ring (19) of the cores (16) and spacers (18A, 18B) centered on the axis (14). At least one of the non-magnetic spacers is a multi-piece assembly (18A) including a shim (32, 49) having a width selected to provide the circumferential preload within a predetermined range.

摘要： Plastic deformation and nicking of the conductors (30) of the end turns (20) in the stator (10,12,14) of a dynamoelectric machine during the installation of a temperature sensor (26) is avoided by locating the temperature sensor (26) in a gap (22) between the coils defining adjacent end turns (20), thereby providing a machine capable of rapidly responding to excess heat even in a locked rotor situation before detectable levels of smoke, gas, and odors are generated.
