Abstract
Soft magnetic cores of electrical machines are typically
made of electrical steel sheets by stacking them
together. Recent development of powder bed processing of
metal printing, e.g., through selective laser melting, is
opening up interesting opportunities in the field of
electromechanics, too [1], [2]. Selective laser melting
is a process where objects are formulated by melting
powder particles together layer by layer.Application of
additive manufacturing in the production of soft magnetic
cores, especially those of reluctance machines, appears
interesting and potentially groundbreaking. Soft magnetic
cores are used in electrical machines to guide the flux
and to improve the performance. More comprehensive
optimization of the magnetic circuit without the
limitations of conventional subtractive and formative
manufacturing methods can result in designs with
significantly enhanced performance and notably lower
material consumption and costs. The former is
particularly true for the transverse flux reluctance
machines [3].While the possible gains of 3D printing in
electrical machine manufacturing have been lately
addressed in some publications [2], the number of
practical examples presented in the literature is rather
limited. In this work, we study the manufacturing of the
soft magnetic cores through selective laser melting and
perform a characterization of the samples. Our main
objectives are to explore: 1) how suitable typical
materials of soft magnetic cores are for selective laser
melting, 2) how well the characteristics of the printed
samples meet the requirements of modern electrical
machines.
