文摘
- •
Cylinder shape piezoelectric element generates motion of a rotor.
- •
Angular position of table is detected by integrated optical encoder.
- •
Maximal displacements of contact zone elements almost coincide at nearly 125 kHz.
- •
Motion trajectory of contact zone elements is defined by elliptical curve.
- •
Rotary table angular resolution equals approximately 8 μrad in both directions.
