Chapter 6 of report KD 578 about the VIRYA-6.5 has been reviewed. At page 12, an alinea is added about the use of an alternative gear box frame size 100 with in parallel shafts. A second alinea is added in which it is mentioned that instead of a 4 kW motor it is possible to use a 5.5 kW motor frame size 112 L as generator for both type of gear boxes. The advantage of a bigger generator is that the generator isn’t overloaded at high wind speeds for the gear ratios i = 12.4 and i = 12.3
