摘要:
In certain embodiments, an electromechanical device includes a rotor (54) having a rotational axis (26), and a stator (10) disposed about the rotor (54). The stator (10) may include a circumferentially laminated section (14) comprising a plurality of circumferential segments (28, 30) disposed one after another in a circumferential direction relative to the rotational axis (26). The stator (10) also may include a radially laminated section (16) comprising a plurality of radial segments (40) disposed one after another in a radial direction relative to the rotational axis (26). In addition, the stator (10) may include an axially laminated section (12) comprising a plurality of axial segments (18, 20) disposed one after another in an axial direction relative to the rotational axis (26).

A superconducting electrical machine (100) is described. The superconducting electrical machine (100) may include an armature coil (110) made of a high temperature superconducting material (120), a cooling system (130), and a field coil (200). The cooling system (130) may include a cryostat (140) surrounding the armature coil (110) and a foam insulation (190) surrounding the cryostat (140).
摘要:
A apparatus for low AC loss thermal shielding includes a plurality of thermally conducting fibers (70, 88, 158, 168, 184) positioned along a desired direction of heat conduction. The fibers (70, 88, 158, 168, 184) are electrically insulated from each other. The fibers (70, 88, 158, 168, 184) are bonded together with a matrix (110, 170), and a thermal link (126) connects the bonded fibers (70, 88, 158, 168, 184) to a cryogenic cold head (144).
