Report KD 723 can be copied for free from my website:
www.kdwindturbines.nl at the menu KD reports. The title of this report is: "Ideas about an 18-pole, 2-phase permanent magnet generator using the housing of a 6-pole asynchronous motor frame size 100 for driving a 0.55 kW motor of a centrifugal pump". In chapter 6 an alternative 6-pole armature is described which can be used in combination with the standard 6-pole, 3-phase winding. Figure 1 of this report is added as an attachment.
