FORCES OF INTERACTION OF HIGH-COERCIVE PERMANENT MAGNETS ACTING BETWEEN SECTIONS OF MAGNETIC SYSTEM AND HALF-COUPLINGS OF MAGNETIC COUPLING, WHEN SYSTEMS AND COUPLINGS ARE USED IN DRIVE OF TIGHT MACHINES

The research on comparison of forces of interaction in magnetic system with high-coercive permanent magnets from alloy of rare-earth elements neodymium-iron-boron with residual magnetic induction of 1.22-1.23 T in axes X, Y, Z is carried out. It is shown that at the same air gap δ between permanent magnets the maximum value is the shear force (attraction) along the Z axis, the shear force along the X axis has a smaller value and the smallest value for the force along the Y axis. Mathematical expressions are obtained by which, at the stage of design development of sealed equipment, the maximum shear forces along the X, Y, Z axes of high-coercive permanent magnets made of an alloy of rare-earth elements neodymium-iron-boron can be calculated.
