Abstract
Content

A custom rotary SQUIGGLE® motor has been developed that sets new benchmarks for small motor size, high position resolution, and high torque without gear reduction. Its capabilities cannot be achieved with conventional electromagnetic motors. It consists of piezoelectric plates mounted on a square flexible tube. The plates are actuated via voltage waveforms 90° out of phase at the resonant frequency of the device to create rotary motion.
