| Application areas: power precision motor in machine-tool industry, astronomy, conveyer facilities, motor-wheel. The super high-torque, reducing gear-free, low-velocity, precision, spark and explosion safe, silent, ultrasonic unidirectional rotation piezoelectric motor PM-57 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 metal cases and is connected with the driver through a special cable. The motor control is carried out by means of a special driver. |
