Two axial-flux permanent magnet generators (AFPMGs) with different field topologies are designed and both electrical and magnetic properties are explored. One of them has three stators and two permanent magnet (PM) rotors at the left-and right-hand sides of a double-sided stator. Another has a double-sided stator at the middle of two PM rotors. These generators have different magnetic flux lines depending on the positions of cores and magnets. The designed AFPMGs are mainly considered for wind energy applications. The transient solutions of finite element analysis (FEA) are obtained based on the equivalent circuit models subjected to three phases and output currents, voltages and cogging torque values are simulated at various speeds. The machines have different power ranges from 2.7kW to 150 W and cogging torque values which change due to their flux topologies from 20 mNm to 10 Nm at 600 rpm. © 2013 IEEE.
