Abstract—Transverse Flux Linear Motor (TFLM) is getting to be widely used in low speed and high power systems. For easy and rigid fabrication, solid core is more useful than laminated core, but core losses are increased, which makes efficiency decreased. Estimating core losses and selecting core types are important in design process to make a compromise high efficiency with effective manufacturing. Therefore, this paper proposes a rapid eddy current loss calculation method for Transverse Flux Linear Motor. The calculation is carried out with the aid of three dimensional Equivalent Magnetic Circuit Network Method (3D EMCN) and 2D Finite Element Analysis Method (FEM). Since the analysis of TFLM is a truly 3D problem, 3D EMCN is used to calculate magnetic field as a source of eddy current. Then 2D FEM is used to calculate eddy current loss rapidly with equivalent analysis models. The usefulness of the proposed method is discussed by comparing the calculation results with the results by another core loss calculation method and experiment.
