Two-dimensional analytical modeling of permanent magnet synchronous generator

This paper demonstrates the 2-D modeling analysis of permanent magnet synchronous generator with axial flux topology used in wind turbines. A detailed study is performed based on analytical model in purpose of obtaining the expressions of magnetic field components in various domains of the generator written as Fourier series expansions. This generator has classical slot's shape and surface permanent magnets. The analytical model should be accurate enough to be used in a preliminary machine design, as well as facilitating its design process. This analytical model design that uses the separation of variables techniques depends on the solution of Maxwell's equations. It has been modeled, and implemented in MATLAB.
