Claim Text:
1. A rotary motor comprising: a vibrating motor body substantially enclosed within a housing, wherein the vibrating motor body is substantially a tube having two orthogonal first bending modes; a shaft frictionally coupled to the vibrating motor body, the shaft arranged to rotate in at least one direction about a rotation axis in response to the vibrating motor body, wherein the shaft is frictionally coupled the vibrating motor body by a force substantially perpendicular to the rotation axis; at least one unbalanced mass coupled to and moveable with the shaft to generate human-detectable vibrations in response to a motion of the shaft; and one or more bearings supporting the shaft and connected to the housing, wherein the one or more bearings define the axis of rotation of the shaft.
