Piezoelectric motor PM-20R

Application areas: precision instrument engineering. The high–torque, start-stop mode, low-velocity, precision, silent, ultrasonic reverse rotation piezoelectric motor PM-20R is intended for forming both continuous and step rotation mode as well as accurate angular positioning. When the piezoelectric motor is de-energized it works as a position holder. The motor is manufactured in a single aluminum cases and is connected with the driver through a special cable. The motor control is carried out by means of the “RM” driver.
