|Application areas: precision instrument engineering, robotics. Piezoelectric motor PM-20RS with feedback sensor has been manufactured on the bases of the piezoelectric motor PM-20R. The motor is manufactured in a single aluminum cases and is connected with the driver through the special cable. The sensor is placed on the case via special placing points. The motor control is carried out by means of the driver “RM” The sensor used is a standard optical encoder of MOZ series produced by Megatron company with a number of revolution marks from 60 to 1500.
