ABSTRACT:
Axially elongated drive modules are interconnected at their opposite ends angularly spaced supports in a polygonal arrangement on an inner ring to establish tensile stress therein, while intermediate module centers are spaced from an inner shaft by solenoid locks. Each module includes at least two magnetostrictive rod elements held in axial alignment at their adjacent ends by a coupling, through which the module is radially spaced from the common axis. Drive coils electrically energized to generate magnetic fields cause simultaneous elongation and contraction of the rod elements to apply unidirectional torque to a rotor formed by either the outer ring or the inner shaft.
