摘要： An electromagnetic thrust bearing having reduced windage losses, improved structural integrity, and enhanced electromagnetic flux density. The present invention provides an electromagnetic thrust bearing having a first annular stator segment and a second annular stator segment joined thereto to define an annular electromagnetic coil chamber having an L-shaped cross-section. By employing first and second stator segments, the electromagnetic coil can be precision wound onto one segment without interference from the other segment, and then the two segments can be joined after the precision winding has been performed. The first segment is joined to the second segment at a location remote from the stator poles to thereby provide a more structurally sound assembly able to better withstand loads imposed thereon. The stator segment pole faces include axially extending lips to maximize electromagnetic flux density and thus load carrying capacity.

摘要： A magnetic actuator core is provided for a radial bearing that supports a rotor for rotation about an axis. The magnetic actuator core includes a back iron, and a plurality of poles spaced circumferentially about the axis and extending radially from the back iron. Each of the poles has a taper wherein the circumferential width of the pole tapers from larger to smaller as the pole extends from the back iron.

摘要： A torque tube assembly for transmitting rotational force from a first end to a second end includes a number n of concentric elongate torque tubes, where n is an odd integer greater than or equal to three. The concentric elongate torque tubes are connected for co-rotation. A serpentine thermal conduction path is defined between the first end of the torque tube assembly and the second end of the torque tube assembly, and includes at least a portion of each of the concentric elongate torque tubes.

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： An electrodynamic machine has a winding and a switching arrangement effectively dividing the winding into individually controllable portions. During a first operating condition, current flows through the entire winding in a manner controlled by the switching arrangement. In a second condition, the switching arrangement restricts current flow to only a portion of the winding. The second condition effectively reduces the inductive capacity of the winding.
