Physical properties of permanent magnets for magnetic circuits of electric machines (in English)
Polimery 2013, No 2, 127
The article presents the results of physical properties investigation of bonded permanent magnets — so-called dielectromagnets. These permanent magnets Nd-Fe-B were made by bonding a hard magnetic powder with a binding agent. For purposes of this research several hard magnetic powders were selected. Hard magnetic powders were obtained from melt-spun ribbon of Nd-Fe-B alloy. The physical properties of sintered magnets from groups such as: ferrite, Nd-Fe-B and Sm-Co were also measured.
