Abstract :
In this paper, we examined overhang effects based on overhang length and material of rotor core by using 2D and 3D static FEM analysis, and proposed 2D dynamic FEA method considering overhang parameter which gives good and rapid results. The proposed method is verified by the experimental results of no load and short-circuit test. The PMG has 13 mm overhang length, spoke type ferrite permanent magnet and 1800 rpm speed.
