Report KD 710 can be copied for free at the menu KD-reports. The title of this report is: “Calculations executed for the 3-bladed rotor of the VIRYA-5B3 windmill (lambda design = 6) meant for connection to the axial flux generator of Hefei Top Grand type TGET450-5KW-300R”. This report contains calculations of the rotor geometry and determination of the generator characteristics for a resistance load, for a grid connected inverter load such that the optimum cubic line is followed and for short-circuit such that the generator is used as a brake to stop the rotor.
