Abstract
A ratcheting micromotor includes a ratchet bar defining ratchet teeth along an edge thereof, and first and second ends in opposition to one another. The first end is adapted to be coupled to an object to be moved. A spring is coupled on one end thereof to the second end of the ratchet bar and adapted to be fixed at another end thereof to a base. A bi-directional actuator configured for linear movement in one of a first direction and a second direction, and when energized has a common yoke coupled to a central portion thereof for movement in correspondence therewith. The common yoke includes teeth formed along an edge and positioned such that its teeth engage a portion of the ratchet teeth. A control system energizes the bi-directional actuator to move, alternately, in the first direction and the second direction.
