摘要:
A stator winding insulation for improving the dielectric and thermal properties of a main insulation of a conductor bar of an electric machine. The stator winding insulation includes a mica band having at least one layer-like carrier composed of longitudinal threads and transverse threads and a mica-containing layer fixed to at least one face of the carrier with the aid of a binder. In the layer-like carrier, the volume ratio of the longitudinal threads to the transverse threads is greater than or equal to 2.5:1 and a weight ratio of the mica in the mica-containing layer to the layer-like carrier in the mica band is greater than or equal to 6:1.
摘要:
The stator winding of an electrical machine comprises conductor elements which are spaced apart from one another, are electrically insulated from one another and are surrounded over their entire length by common main insulation. The cavities, which are caused by the arrangement on both bar narrow sides of the conductor elements and the main insulation, are filled with an electrically semiconductive compound which, for its part, is covered by an electrically semiconductive strip. In order to provide a smooth bar surface, the electrically semiconductive strip is composed of a fiber-reinforced plastic, which has incisions on alternate sides of the narrow sides of the conductor bar oriented transversely with respect to the bar's longitudinal direction; these incisions are deeper than half the strip width and have a cut width which is on the order of magnitude of the strip thickness.

摘要:
A positioning technique for aligning an X-ray lens (28) is described. A positioning apparatus (16) comprises a lens mounting component (44) and a positioning component (42). The positioning component (42) includes at least one goniometer stage (64, 66) having a center of rotation that substantially coincides with the X-ray emitting portion (36) (“hot spot”) of the X-ray source (12). The provision of one or more goniometer stages (64, 66) and, if required, one or more additional translation stages (60, 62) facilitates the adjustment of the X-ray lens (28) and makes the adjustment more intuitive.
