Sorry to be late, i was out.
Current engines have its stages fixed in position to one or two (Trent engines three) concentric shafts, depending of them belonging to high or low
rpm sections. This means that a lot of stages moves at the same rotational speed and in doing so some efficiency goes down the drain.
In this design each stage is mechanically independent and electrically connected to each other, they are motors (compressor, fan) or generators
(turbine) and they work at their optimal rpm each.
The space that leaves the shaft is a hole through out the engine that serves multiple purposes, it is a way for bypass air without increasing the
front section, it can be the ramjet section of the engine for high speeds and is an "electrical highway" that flow the electricity over the stages.
Synergy in action.
Hope it helps
