Abstract : Axial elongation of a magnetostrictive element during a power phase of operation in a motor, effects conversion of axial force to a torque applied to a rotor through cam discs held in axial engagement by a clutch disc during axial force transfer. Rotor rotation by such torque angularly displaces the cam discs relative to each other against the bias of a spring device during the power phase, followed by a free wheeling phase during which axial withdrawal of the clutch disc occurs in response to contraction of the magnetostrictive element and angular restoration of the cam discs to a limit position under the spring bias.
