IDEA #835AAX New Computerized Ultrasonic Piezoelectric Nanomotor Pm-20rs

THE SCIENCE AND TECHNOLOGY CENTER IN UKRAINE NEW COMPUTERIZED ULTRASONIC PIEZOELECTRIC NANOMOTOR PM-20RS Description LILEYA's nano-positioning rotation piezoelectric motor PM-20RS (fig. 1) on the bases standing wave combine high torque, variable speed, and high angular resolution using a shaft-mounted 1000 counts/revolution optical encoder. The piezoelectric motor PM-20RS 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. Piezoelectric motor PM-20RS with feedback sensor has been manufac­ tured on the bases of the piezoelectric motor PM-20R (www.piezomotor.com.ua). The motor is connected with the controller PSF-3 IVF IBM through the special cable. Communication with the computer is carried out through the COM port. The software PSF-3 IVF enable to work with 3, 6, 9, 12 motors simultaneously. Innovative Aspect and Main Advantages The motor operation employs the radial oscillation of a proprietary ring-based piezoelectric resonator operating at approximately 73 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 steps 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 1.0 arcsec corre­ sponds to duration of excitation of between 50 and 60 μβ. The light-weight rotor of the motor (approximately 30 g) and the high torque 0.10 N*m results in high acceleration, so that the time from a demand to maximum speed (60 rev/min) is less then 0.3 ms. The corresponding decelera­ tion torque is 0.11 N*m. These characteristics facilitate a smooth transition from an angular step of 1.0 arcsec to con­ tinuous motion, a wide range of angular velocities, from 1.0 arcsec/s to 60 rev/min (equivalent to about 6 orders of magnitude dynamic range).
