NANOTTEECCHHNNOOLLOOGGYY • APPLICATIONRESEARCH IINN THEFIELD OOFF NANOTTEECCHHNNOOLLOOGGYY Description LILEYA’s nano(cid:2)positioning inexpensive unidirectional rotation piezoelectric motor UPM(cid:2)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(cid:2)22 can be used in either continuous or stepper mode to provide accurate angular positioning. When the piezoelectric motor is de(cid:2)energized, it operates as a position(cid:2) ing holder (brake) with practically undetectable backlash and drift. The in(cid:2)built angle positioning system (using the magnet "marks" established by the customer himself) enables to real(cid:2) ize 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(cid:2)20 www.piezomotor.com.ua ) Innovative Aspect and Main Advantages The motor operation employs the radial oscillation of a propri(cid:2) etary ring(cid:2)based piezoelectric resonator operating at approxi(cid:2) mately 80 kHz. Each cycle of radial nano(cid:2)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(cid:2)move(cid:2) ment 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 exci(cid:2) tation of between 40 and 60 μs. The light(cid:2)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 corre(cid:2) sponding deceleration torque is 0.4 N*m. These characteris(cid:2) tics facilitate a smooth transition from an angular step of 0.5 arcsec to continuous motion, a wide range of angular veloci(cid:2) ties, from 0.5 arcsec/s to 30 rev/min (equivalent to about 6 orders of magnitude dynamic range).
