Dear Hugh
I have written a new report KD 723 which 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.
