It is known that the effective work of drum-type magnetic separators is determined only by those forces which act in the radial direction, since strongly keeping magnetic mix on the drum surface with their transportation to the output of magnetic product. The disadvantage of this magnet system is the insufficient value of the magnetic force component of field which acts on the magnetic particles in the direction of their precipitation on the drum surface. This system is used for slight magnet particles precipitation. Mathematical simulation and calculation of magnetic field with the antiradial magnetization shows an increase in the precipitant magnetic forces (by normal component of total magnetic force) by 10%-30% in comparison with the analogous in the sizes, known as magnetic system. Non-uniformity of magnetic field of induction on the surface is less to 1.3 and radial magnetic force to 1.7. 相似文献

Vlado Ostovic first proposed pole-changing permanent magnet motor. In his paper, the stator was the same with that of pole-changing induction motor, the rotor was built following the sandwich principle, and some of the stator winding are used as the magnetizing coil. But the rotor structure has many shortcomings. The surface-mounted rotor is advised in this paper. The magnetizing magnetic field by some of the stator windings is calculated, and we find the magnetic field is complex. The direction of the remanence of the permanent magnet is decided by both the radial and tangential component of magnetic field. We also calculate the magnetizing process of permanent magnet by FEM software. 相似文献
