Resonant-structure micromotors

Resonant-structure micromotors operate on the principle of mechanical resonance, so that the armature is driven for maximum displacement and power. The application of resonance in motors is placed in historical perspective and the scaling issues for such resonant systems are identified and quantified. Along with a conventional, tensile-element resonant-structure, an novel, crab-leg flexure system is described, and the stress and flexural spring constant formulas are derived.<
