Report KD 532 gives the rotor calculations of a 3.1 m diameter, 2-bladed rotor made out of Roofmate and glass fibre. A new chapter 6 has been added in which it is checked if this rotor matches with the Chinese axial flux generator of Hefei Top Grand type TGET260-0.5KW-350R. As generator characteristics for a 24 V battery load are not available, these characteristics were estimated from the given specification of the manufacturer.
