In a method an inner segment is first pre-assembled on each of a number of outer segments by at least one fixing element, so as to produce a plurality of segment modules having each a predetermined air gap between the inner segment and the outer segment. The inner segments and the outer segments are assigned to the rotor or stator of the electrical machine. The inner segments of the plurality of segment modules are fastened to an inner assembly device (for example a hub). The outer segments of the plurality of segment modules are fastened to an outer assembly device (for example a supporting structure). Finally, the fixing elements between the inner segments and the outer segments are removed.

Method for assembling a segmented electrical machine while maintaining gaps between segments

A generator includes a stationary stator and a rotor disposed rotatably about an axis of rotation. The stator has a fan drawing air from the ambient air around the generator, wherein the inlet channel is disposed such that air drawn in by the fan is distributed at the core of the stator by the channel over the length of the core in the direction of the axis of rotation. Cooling channels running in the circumferential direction of the core and distributed over the length of the core are disposed on the core, wherein the stator comprises an outlet channel disposed offset in the circumferential direction of the core with respect to the inlet channel. The inlet channel is connected to the outlet channel by the cooling channels, such that air from the inlet channel flows through the cooling channels into the outlet channel.

The invention relates to a compressor system (), particularly for conveying gases or gas/oil mixtures in the offshore area, with a seawater-tight housing () with at least one access opening () for gases or gas/oil mixtures which are to be compressed, and with at least one outlet opening () for the compressed gases or gas/oil mixtures. In the housing (), a compressor () is disposed, which is connected at the inlet side to the access opening () and, at the outlet side, to the outlet opening (). An electric motor (), which has a stator assembly () and a rotor assembly () for driving the compressor (), is disposed in the housing (). According to the invention, the stator assembly () can be cooled over an inner side (GI) of the housing () of the compressor system ().

A logic module is disclosed for construction in an integrated digital circuit for promoting testing of the integrated circuit. A latch module is provided for functioning as a latch, as a back-coupled shift register, and in one embodiment of the invention as a linear shift register. The latch module is formed of a plurality of basic cells each of which has a flip-flop with associated logic gates, one of which is an exclusive OR gate. The latch module also has an input, parallel data inputs and parallel data data outputs. For functioning in the back-coupling mode, an exclusive OR gate is connected between at least one of the flip-flops and the input to the latch module.
