IDEA #40MSGQ New Start-Stop Ultrasonic Piezoelectric Nanomotor Upm-22 With Ultra-High Resolution And Ultra-High Torque For Nano-Positioning System And Other Applications

THE SCIENCE AND TECHNOLOGY CENTER IN UKRAINE NEW START-STOP ULTRASONIC PIEZOELECTRIC NANOMOTOR UPM-22 WITH ULTRA-HIGH RESOLUTION AND ULTRA-HIGH TORQUE FOR ΝΑΝΟ-POSITIONING SYSTEM AND OTHER APPLICATIONS Description 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 posi­ tioning 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 driv­ er to UPM-20 www.piezomotor.com.ua) 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-oscilla- tion by means of the rotor produces a single step of angu­ lar 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 exci­ tation. The minimum step approximately 0.5 arcsec corre­ sponds to duration of excitation of between 40 and 60 μβ. 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 decelera­ tion 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).
