Abstract: The
principle that reciprocating in line is transmitted using the magnetic
field force is studied. A magnetic circuit constructed by high
performance rare-earth permanence magnetic material is developed to
transmit the reciprocating in line. For the magnetic circuit, a model of
calculating the axial force transmitted by the magnetic field is
established by the theory of equivalent magnetic charge, and an
experimental rig for the magnetic force transmission is designed and
made. The model is verified by the experiments. The model determines the relation between the axial magnetic force with the magnetic ring
thickness, the radial clearance, the internal magnetic ring diameter,
and the radial wideness ratio of the tow rings. Effects of the
parameters on transmitting the magnetic force are studied by the
sensitivity analysis. The analysis shows that decreasing the radial
clearance of the two rings increases the magnetic force transmitted by
the magnetic field.
