Piezoelectric motor has stator made from a thin disk with piezo-electric element and peripheral cut-outs which form flexible elements able to propel a thin disk rotor in contact

摘要

The disk rotor (13) of the motor rotates about a shaft in a bearing mounted in the top of the motor frame and is held in position by a blade spring (15) acting through the stator (10,11). The stator (10) comprises a disk made from brass or steel and has turned up cut-outs (11) which are in spring contact with the rotor (13). A piezoelectric element (12) is glued to the stator (10) and drives the rotor through vibration of the cut-outs (11).
