The influences of the number of winding turns, area of pole face, magnet thickness and air gap on magnetic force, current stiffness, position stiffness and nonlinearity are all shown by the characteristic curves of force-area of pole face-air gap, force-magnet thickness-area of pole face, force-air gap-magnet thickness, current stiffness (or position stiffness)-area of pole face-air gap, current stiffness (or position stiffness)-magnet thickness-air gap, and current stiffness (or position stiffness)-magnet thickness-area of pole face.Read More
