Axial flux PM coreless stator machine development for low speed wind generator

Developing nations' rural populations need small electrical power sources for battery energy storage. Development of a micro-wind generation permanent magnet generator with no or low cogging torque would be a major advancement for low wind speed areas. Here two aspects of the design for this type of wind generator are investigated, with favorable outcomes. These outcomes point the research way forward for development of a revised proto-type low wind-speed generator based on axial flux permanent magnet machine.
