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.
