A stator or a rotor for use in an electrical machine, the stator or rotor comprising a composite element comprising a rigid mass (102) suitable for comprising at least one magnetostrictive electrode bar, at least one magnetostrictive electrode bar and a piezoelectric material (106) in between said rigid mass material and said magnetostrictive electrode bars (104). The rigid mass (102), the magnetostrictive electrode bars (104) and the piezoelectric material (106) are arranged such that applying a voltage between the rigid mass (102) and one or more magnetostrictive electrodes, causes ...
