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 piezo-electric 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 manufactured 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-oscillation 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 nano-movement depends on the number of single angular steps made, which depends on the duration of excitation. The minimum step approximately 1.0 arcsec corresponds to duration of excitation of between 50 and 60 ?s. 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 deceleration torque is 0.11 N*m. These characteristics facilitate a smooth transition from an angular step of 1.0 arcsec to continuous 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).
