Abstract

See full text

Piezoelectric motor that provides high speed and bi-directional operation. A first rotor is disposed about a first shaft, and a second rotor separate from the first rotor is disposed about the first shaft and a second shaft. Each of the rotors and shafts are centered on a common axis. An annular shaped first piezoelement is centered on the axis and fixed to the housing. First and second annular piezoelements are disposed within the first rotor, configured to motivate rotation of the second shaft in a first rotation direction when stimulated with a first exciter voltage. The third and fourth piezoelement are disposed within the second rotor, configured to motivate rotation of the second shaft in a second direction (opposed from the first direction) when stimulated with an exciter voltage.
