1. the multiple degrees of freedom rotary piezoelectric motor under the low frequency simple oscialltor pattern is characterized in that:

  • include rotor (1), stator (2), piezoelectric ceramic (3), resonance reed (4), substrate (5) and pedestal (6);

    Wherein, described resonance reed (4) is made up of skewback (41) and resonant reed (42) that one is installed, and the top and bottom of described skewback (41) are connected with substrate (5) with described rotor (1) respectively;

    Be wrapped on the described skewback (41) the rotatable certain angle of described resonant reed (42);

    Described piezoelectric ceramic (3) is tubulose, and is enclosed within on the described skewback (41), and encases described resonant reed (42);

    Described substrate (5) is fixed on the described pedestal (6);

    Described stator be fixed on described skewback (41) on.
