Piezo Rotary Motor for Optical Instrumentation Tech Note

A great many factors come into play when selecting a drive system for a portable precision instrument: The installation space available, the velocities, the accelerations and positional accuracy required, the energy consumption and the reliability of the motorization selected. When increased demands are placed on an application, PILine® ultrasonic piezomotors are the obvious practical alternative to classic DC stepper motor combinations. Thanks to the employment of piezomotors, the performance of the geodesic measurement systems from Leica Geosystems AG has increased drastically.
