NEW HIGH TORQUE COMPUTERIZED ULTRASONIC PIEZOELECTRIC NANOMOTOR PM22RS FOR ROBOTIC APPLICATIONS Description LILEYA’s nanopositioning rotation piezoelectric nanomotor PM22RS (fig.1) on the bases standing wave combine high torque, variable speed, and high angular resolution using a shaftmounted 1000 counts/revolution optical encoder. The piezoelectric motor PM22RS can be used in either continu ous or stepper mode to provide accurate angular positioning. When the piezoelectric motor is deenergized, it operates as a positioning holder (brake) with practically undetectable back lash and drift. Piezoelectric motor PM22RS with feedback sensor has been manufactured on the bases of the piezoelec tric motor PM22R (www.piezomotor.com.ua). The motor is connected with the controller PSF3 IVF IBM through the spe cial cable. Communication with the computer is carried out through the COM port. The software PSF3 IVF enable to work Fig.1 Piezoelectric NanoMotor PM22RS with 3, 6, 9, 12 motors simultaneously. Devices on the bases PM22RS Innovative Aspect and Main Advantages The motor operation employs the radial oscillation of a propri etary ringbased piezoelectric resonator operating at approxi mately 80 kHz. Each cycle of radial nanooscillation by means of the rotor produces a single step of angular 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 nanomove ment depends on the number of single angular steps made, which depends on the duration of excitation. The minimum Fig.2 MicroRobotic System Fig.3 MicroRobotic System step approximately 0.5 arcsec corresponds to duration of exci PRS3 for control of PRS3 for well plate tation of between 40 and 60 μs. The lightweight rotor of the computer applications motor (approximately 40 g) and the high torque 0.50 N*m results in high acceleration, so that the time from a demand to Stage of Development maximum speed (30 rev/min) is less then 0.3 ms. The corre LILEYA’s unique designs is being patented : sponding deceleration torque is 0.55 N*m. These characteris tics facilitate a smooth transition from an angular step of 0.5 • in the World ( PCT Application) arcsec to continuous motion, a wide range of angular veloci • in Ukraine ( Application Serial N 2006 11804) ties, from 0.5 arcsec/s to 30 rev/min (equivalent to about 6 LILEYA builds motors with superior high performance charac orders of magnitude dynamic range). teristics and it can produce 1000 motors per year now, larger Technical data for piezoelectric nanomotor PM22RS production is possible.
