The linear oscillating actuator (LOA) is an attractive option for the compressor due to their high power density and efficiency. Due to the segmented outer stator structure of the LOA, 3-D finite element analysis (FEA) is essential for calculating accurate electromagnetic loss, but it requires high computation cost. Thus, in this paper, we propose a method to reduce the computation cost calculating the iron loss using only 2-D axisymmetric FEA. To reflect the magnetic flux density increased according to outer stator structure of the LOA, the 2-D axisymmetric FEA magnetic flux density was corrected by applying an equivalent coefficient for the ratio of circumferential direction volume between full and segmented outer stator core. By using the proposed method, efficiency of the LOA can be accurately calculated without any 3-D FEA, thus the LOA can be designed efficiently.
