Turret with positioning in two axes and piezoelectric motorisation |
摘要 |
<p>The device has a motor (13) e.g. progressive wave piezoelectric motor, in which each motor has a stator comprising a stator crown wheel (15) supported by a yoke or base. A rotor has an annular rotor pad (19) coaxial to the wheels around site axis (XX) or sliding axis (YY) and in axial support against the wheels under preconstraint force. A piezoelectric ring (17) is coaxial to the wheels and applied against a radial surface of the wheels so as to excite the wheels and provoke displacement of the rotor when excitation sectors of the rings are supplied with current.</p> |
