10. Mount the last rotor segment as follows:
• The left-hand T-sliding block holding the last rotor segment is also the right-hand
T-sliding block holding the rotor segment that was mounted second to last. The fixing
screws on the left-hand T-sliding block for the last rotor segment are therefore
already loose. Loosen the fixing screws on the right-hand sliding block for the last
rotor segment. You can then insert the last rotor segment into the T-sliding blocks
without jamming or canting.
• Slide the last rotor segment between the T-sliding blocks, and up to the mechanical
stop.
1 First rotor segment n - 1 Penultimate rotor segment
2 Second rotor segment n Last rotor segment
3 Third rotor segment
Due to the magnetic attraction force, the last rotor segment is usually pulled up to the
first rotor segment. The last and first rotor segments touch so that no gap arises.
On the other hand, an unevenly larger gap results between the last and the
penultimate rotor segment than between the other rotor segments.
