LILEYA’s nano-positioning inexpensive unidirectional rotation piezoelectric motor UPM-22 (fig.1) on the bases standing wave combine high torque, variable speed, and high angular resolution using new piezoelectric generator. The piezoelectric motor UPM-22 can be used in either continuous or stepper mode to provide accurate angular positioning. When the piezoelectric motor is de-energized, it operates as a positioning holder (brake) with practically undetectable backlash and drift. The in-built angle positioning system (using the magnet "marks" established by the customer himself) enables to realize the shaft fixation in chosen positions. The motor control is carried out by means of the driver on two lines of the XP1 joint (see driver to UPM-20 )

Innovative Aspect and Main Advantages

The motor operation employs the radial oscillation of a proprietary ring-based piezoelectric resonator operating at approximately 80 kHz. Each cycle of radial nano-oscillation by means of the rotor produces a single step of angular movement. A continuous sequence of single angular step results in a smooth angular/rotary movement of the shaft on which the rotor is mounted. The magnitude of the resulting nano-movement depends on the number of single angular steps made, which depends on the duration of excitation. The minimum step approximately 0.5 arcsec corresponds to duration of excitation of between 40 and 60 μs. The light-weight rotor of the motor (approximately 20 g) and the high torque 0.5 N*m results in high acceleration, so that the time from a demand to maximum speed (30 rev/min is less then 0.3 ms. The corresponding deceleration torque is 0.4 N*m. These characteristics facilitate a smooth transition from an angular step of 0.5 arcsec to continuous motion, a wide range of angular velocities, from 0.5 arcsec/s to 30 rev/min (equivalent to about 6 orders of magnitude dynamic range).
