On my website, at the bottom of the list with KD-reports, there is a new manual of the VIRYA-1.81 windmill available. This windmill has an axial flux PM-generator with no iron in the stator disk and the coil cores and the peak efficiency will therefore be very high. The sticking torque will be very low resulting in a low starting wind speed. The manual contains information about manufacture and mounting and at the end, detailed drawings of the rotor and the generator.

The calculations of the generator and the rotor are given in the free public report KD 631. Figure 2 of KD 631 gives a cross section and a front and a back view of the generator which gives a good impression of the construction. The generator is not yet built and tested. At the menu VIRYA-folders, there is a separate folder with a short description of six free VIRYA-designs including the VIRYA-1.81. All information is given in (not perfect) English.
