An improved design of an axial flux permanent magnet machine is obtained using finite element method and sensitivity analyses. A 9-phase axial flux permanent magnet machine with one-rotor-two-stators configuration equipped with concentrated winding is investigated and condition for minimum cogging torque and voltage harmonics is deduced. Owing to three dimensional structure of axial flux permanent magnet machines, 3-D finite element model is used to model and analysis of the generator performance characteristics. Sensitivity of the machine is evaluated respect to variation of its geometric parameters.
