Report KD 596: “Ideas about a 12-pole axial flux generator for the VIRYA-1.66 windmill using 12 neodymium magnets size 25.4 * 25.4 * 12.7 mm. Design report of the rotor (lambda design = 4.5, B = 3, stainless steel blades).” has been added to the menu KD-reports. The 12-pole generator described in this report is derived from the 8-pole generator of the VIRYA-1.36 as described in report KD 571. However, in chapter 10 of KD 596, an alternative 2-layers winding is described with which it is possible to get more copper in the stator and therefore to generate more power at the same rotational speed.
