<p>A rotor disk (101) is impelled by stator plates (104) vibrated normally and tangentially by piezoelectric units (108,120,107) at a basic and harmonic frequency. The stator plates drive the disk through superelastic footplates with elastic elements (22) and are connected to the frame (102) through a first weight (120) and spring (109). The stator unit (123) comprises a second weight which may vibrate with and in opposition to the first weight</p> |
