Abstract— Transverse Flux Linear Motor (TFLM) is getting
to be widely used in low speed and high power systems. For easy
fabrication, solid core is more useful than laminated core.
However, eddy current losses are increased in solid core, and it
makes efficiency decreased. Some experiment results show the
fact. Therefore, estimation of eddy current losses is important to
select core type. This paper describes a rapid practical technique
to analyze the eddy current losses in solid and laminated cores of
a TFLM. The calculation is carried out with the aid of 3D
Equivalent Magnetic Circuit Network Method and 2D Finite
Element Analysis Method. The calculated results and the limits
of the proposed methods are discussed.
