The relationship between the dimensions and positioning between the coil assembly's coil winding section
and magnetic way's magnets is shown here.
Maintain the following air gaps when installing. Make sure that the coil assembly and magnetic way do
not interfere during the stroke.
2. Move the coil assembly back and forth several times over the magnetic way from end to end, making sure
that the coil assembly and magnetic way are not touching each other and that no foreign objects such as
magnetic particles are present.
