Abstract
A stator or a rotor for use in an electrical machine comprises a composite element having a rigid mass suitable for including at least one magnetostrictive electrode bar, at least one magnetostrictive electrode bar, and a piezoelectric material in between the rigid mass material and the magnetostrictive electrode bars. The rigid mass, the magnetostrictive electrode bars and the piezoelectric material are arranged such that applying a voltage between the rigid mass and one or more magnetostrictive electrodes, causes piezoelectric effects in the piezoelectric material inducing stress in the bi-axial plane of the at least one magnetostrictive bar and an altered permeability of the at least one magnetostrictive bar in a direction perpendicular to the bi-axial stress plane.
