More Information
Summary:An ultrasonic electromechanical stator includes two vibration bodies, a link member connecting the two vibration bodies along a connection direction and a stator support. Each of the vibration bodies includes a respective electromechanical element and is configured to perform bending vibrations in a bending direction when an alternating voltage is applied to the electromechanical elements. The link member has a contact portion intended for contacting a surface of a body to be moved. The link member has a respective mechanical link connecting portion to the vibrating bodies. Each of the vibration bodies is mechanically attached to the stator support by at least two attachment tabs on at least one side, in a direction transverse to both the connection direction and the bending direction, of the respective vibration bodies. Also an ultrasonic electromechanical motor having such an ultrasonic electromechanical stator is disclosed.
