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.

Abstract
A rotary motor and a method of making the same include a vibrating motor body which has two orthogonal first bending modes and is substantially enclosed within a housing. A shaft is frictionally coupled to the vibrating motor body and is arranged to rotate in at least one direction about a rotation axis in response to the vibrating motor body. The shaft is frictionally coupled the vibrating motor body by a force substantially perpendicular to the rotation axis. One or more bearings support the shaft, are connected to the housing, and define the axis of rotation of the shaft.
