Abstract: A brushless motor includes a stator disposed along an axis and a rotor disposed radially inward from the stator. The rotor includes a core, a plurality of first magnets and a plurality of second magnets configured to have opposite poles relative to the plurality of first magnets. The plurality of first and second magnets may each have a substantially rectangular cross-section and are in contact with a substantially flat surface carried by the core that faces radially outward.

Abstract: A link apparatus includes a tubular member that retains 90% of ultimate tensile strength at a temperature of up to 625°. Two conical adapters are mechanically joined to respective ends of the tubular member. Two rod ends include a threaded shank and a socket. One threaded shank is threaded into a right hand threaded base of one conical adapter, and the other threaded shank is threaded into a left hand threaded base of the other conical adapter. Each of the sockets have a bearing assembly disposed therein including an outer race, a ball disposed therein, and a low-friction liner disposed between the outer race and ball for mitigating moment loading on the tubular member. The cross-sectional area of the tubular member is about equal to the cross sectional area of the rod ends. The tubular member is tensionable by rotation relative to the rod ends.

Abstract: A low friction load slot bearing assembly has a ball and an outer race in which the ball is positioned. The outer race includes an inner engagement surface contoured to a shape complementary to an outer surface of the ball, a first slot located in a face of the outer race, a second slot located in the face of the outer race, and a lubricous liner disposed on the inner engagement surface and on surfaces defining the slots. The low friction aspect is imparted to the load slot bearing assembly via the lubricious liner. The ball slidably and rotatably engages the inner engagement surface of the outer race. A load slot bearing system includes a low friction load slot bearing assembly interconnecting two elements. A link apparatus includes a cylindrical member and two low friction load slot bearing assemblies located on or at opposing ends of the cylindrical member.
