“…Another actuator configuration is based on the Wiedemann effect [104][105][106]. According to Smith and Overshott [108], the application of a helical magnetic field allows the magnetic domains to rotate, creating a shear strain in the material.…”

Magnetostrictive actuators play an important role in the perception of usefulness of smart materials and devices. Their applications are potentially wider than that of piezoelectric actuators because of the higher energy density and intrinsic robustness. However, the non-negligible hysteresis and complexity of their characteristics make the design and control quite difficult and has limited their diffusion in industrial applications. Nevertheless, the scientific literature presents a wide offer of results in design and geometries, modeling and control that may be exploited for applications. This paper gives a reasoned review of the main results achieved in the literature about design, modeling and control of magnetostrictive actuators exploiting the direct effects of magnetostriction (Joule and Wiedemann). Some perspectives and challenges about magnetostrictive actuators development are also gathered.

“…. Magnetostrictive effects, as discussed in section 3.2.6, refer to the dimensional changes that occur in the magnetic material when magnetized [28][29][30]. One of the problems associated with electrostatic motors is friction.…”

“…Precision displacements of 10-100 I1lIl with accuracy of positioning up to 0.1 I1lIl or better at 1 ms time scale are easily obtained with a permendur magnetic rod of 10 em length and 1 cm diameter. Permendur is an alloy of 49% Fe, 49% Co and 2% V [28]. It is also interesting to note that this device can be used as a torque sensor when the signal in one of the coils is monitored as a function of the twisting of the magnetic rod.…”

“…The Weidmann effect is a magnetostrictive effect in materials, caused by excitation of twisting strains in a ferromagnetic rod in the presence of axial and circular magnetization fields [28]. The Weidmann effect is used in torsional and linear displacement actuators and its inverse is used to measure instantaneous torque in the crankshaft of motors [29].…”
