This paper presents the design of 3kW axial flux permanent magnet generator considering wind turbine characteristics. The machine has ironless stator to produce sinusoidal voltage with less harmonic contents by completely eliminating the cogging torque of the machine. The machine performance is analyzed by finite element analysis since it reduces the time consumption and it used to validate the analytical design of the proposed axial flux permanent magnet generator. The airgap between stator and rotor are optimized, so as to determine the magnet dimensions and stator coil designs. The simulation results of proposed generator prove the reliability of the system for low speed direct drive wind turbine applications.
