Abstract
A puck for a three-dimensional magnetoelastic force transducer, with a cylindrically-shaped body having a circular cross-section, a semi-spherically-shaped first end surface and a second end surface having an annular flange with an outer diameter corresponding to the diameter of the circular cross section of the body; the body comprising a substantially solid magnetoelastic material with a center axis extending between the middle of the first and second bottom surfaces; the body having at least three force-measuring zones equidistantly spaced from the center axis and symmetrically distributed within the body; each of the at least three force-measuring zones having respective holes for receiving excitation and measuring windings; and force transmission paths extending between the intersection of the center axis and the first end surface, the intersection forming a point of application of force to the force transducer, and each of the at least three force-measuring zones to the annular flange.
