ABSTRACT:
A transverse field activated magnetostrictive motor including a magnetostrictive member having a direction of motion transverse to its principal orientation axis, and a reaction surface mechanically coupled to the magnetostrictive member. A travelling magnetic field with a field component parallel to the principal orientation axis of the magnetostrictive member is provided and moved sequentially along the magnetostrictive member to sequentially, locally, decouple the member from the reaction surface to move the member in the direction of motion in relation to the surface.
