Abstract
A magnetostrictive linear actuator, responsive to an external signal, including a housing assembly that encloses a magnetostrictive force train assembly, an excitation means disposed on a component of one assembly, as well as a thermal compensation means disposed on a component of the complementary assembly, and a controller means responsive to the external signal which provides a heat control signal in dependence on the magnitude of the controller signal such that the thermal expansion of the assembly heated by the excitation means will be compensated by a matching thermal expansion induced in the complementary assembly.
