Design and Analysis of Novel Axial Flux Permanent Magnet Generators with Decoupled Stators

This paper presents the design and analysis of novel axial flux permanent magnet generators. They have a single rotor and double-sided stators. Two double-sided stators are magnetically decoupled, thereby generating dual-output voltages. The generated voltages have different frequencies, achieved through a novel rotor magnet arrangement structure. A 2D analytical method is developed to analyze generators. 2D and 3D finite element methods are also utilized for detailed analysis of generators. The performance calculations consider two axial flux permanent magnet generators with different dimensions, speeds, and pole numbers.
