Small Brush DC Motors using Soft Magnetic Composites for 42V Automotive Applications

Influence of temperature on energy loss of dielectromagnetics

“…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.…”
