An overview of the compactness of a range of axial flux PM machines

Abstract

This paper begins with a rev "goodness" of electrical machines concept by Laithwaite. Its correctness when app machines is demonstrated using the metric for which we use the word "compactne Nm/m 3 . Technical advances in the latter century are discussed, as are properties of a that have had a significant impact on m range of axial flux permanent magnet (PM) which are currently in production Corporation are presented, studying in compactness. The paper concludes with a larger machines can indeed demonstrat compactness, although much less dram proposed by Laithwaite, using the air gap sh This discussion includes the difference of th radial and axial flux PM machines.
