Dielectromagnets, also called bonded magnets, are permanent magnets produced by combining hard magnetic powder with dielectric. They have many advantages. One of these for isotropic dielectromagnets is the possibility of multi - pole magnetization in all directions. Dielectromagnets from Nd-Fe-B melt-spun ribbon have good magnetic properties, better than sintered ferrite magnets. Dielectromagnets open new possibilities for the construction of electric machines. The paper presents the advantages of multi - pole dielectromagnets, allowing to replace the multi - pole glued constructions of bipolar permanent magnets. The paper presents the known methods of multi - pole magnetization of permanent magnets, and new solutions for simplification of electric motor designs. Also presented are examples of application of multi - pole Nd-Fe-B dielectromagnets.
