INDUCTOR FOR PULSE MAGNETIZATION OF ARTICLES FROM MAGNETICALLY HARD MATERIALS

摘要

FIELD: electric engineering. SUBSTANCE: device has pair of identical contour electrodes which are made from lines with high conductance and are designed as coaxial cylindrical arcs which adjacent terminal ends are connected to each other by means of single direction jumps so that reciprocal spiral with outer and inner terminals is provided. Single-direction jumps of contour electrodes are designed as U-shaped vertical jumps which bases are supported by outer horizontal faces of terminal ends of coaxial cylindrical arcs which are connected in pairs. Inner opposite terminals of both contour electrodes and identical external terminals of both contour electrodes are designed as L-shaped lines which are located above outer face plane of corresponding contour electrodes. Bases of vertical arms of L- shaped lines are connected to horizontal sections of coaxial cylindrical arcs of corresponding contour electrodes of inductor. This results in possibility of more uniform magnetization inside each given area and increased precision of separation between areas with different polarity. In addition reverse magnetization is applied both to single- and double-sided magnetization of articles under their surface as well as to their through profile reverse concentric magnetization. EFFECT: increased functional capabilities, increased quality of reverse magnetization, elimination of jump-wise alternation in polarity of magnetization inside ring magnetization areas.
