“…4,5 The basic advantages obtainable by abandoning the classic laminated magnetic circuits technology and adopting magnetic powders is the possibility to radically change the design approach, from a 2D vision to a 3D design of the magnetic pattern 6 : the material is isotropic and can carry the flux in all directions with the same properties. In many cases the adoption of parts obtained by molding may be an interesting solution, 7 especially if the desired geometry presents complications when realized with magnetic sheets [8][9][10][11][12] ; such elements may bring to a strong simplification in the production process. 13 In the paper the adoption of a novel SMC material in place of I.I.P.C.…”

The chance to move from 2D to 3D approach in the design of the electrical machines is made possible by the availability of Soft Magnetic Composites (SMC), iron based powders, insulated and pressed to realize shapes otherwise impossible with the traditional lamination sheets technology. Some commercial products are available on the market as “ready to press” powders, which presents good magnetic and energetic properties but are sometimes weak under the mechanical point of view; other products aim at improving this aspect but with considerable process complications and relative cost. The experience of the Authors in the realization of bonded magnets with the adoption of selected organic resins has been partly transferred in the research field of the SMC in order to investigate the possibility to obtain good mechanical properties maintaining the magnetic characteristics of the Insulated Iron Powder Compounds (I.I.P.C.) taken as reference. The paper presents the activity that has been carried out in the realization of SMC mixing iron powders and phenolic resin, in different weight percentages and mold pressures. The obtained results are considered satisfactory under the point of view of the compromise between magnetic and mechanical properties, considering also that the required productive process is simpler. The comparison of the obtained results with those related to commercial products encourages to carry on the research, also because of the reduced cost of the proposed SMC at parity (or better) performance.

“…One of the possible approaches is to replace the classical laminated magnetic circuits of electric machines made from silicon iron sheets with soft magnetic composite (SMC) or iron powder materials [1][2][3]. The results of using these materials are shorter magnetic circuit manufacturing times, a smaller number of components and less scrap.…”

“…Another vital advantage of dielectromagnetic (DM) magnetic cores over the laminated ones is the possibility of spatial shaping of magnetic flux flow propagation [1]. It is beneficial because it enables design of more compact machines of satisfactory parameters that is why DMs find wider application as magnetic cores of various electrical machines, among others: brushless-, claw pole-and universal motors [2,3]. Nevertheless, DMs account for a small fraction of the total number of magnetic components produced, with this attributable in part to a lack of available information on the properties and characteristics of such materials to aid in design and allow objective comparisons of the benefits and drawbacks of such composites compared to more conventional electrical sheet materials.…”
