Micro-angle adjusting device using PMN electrostrictors

A micro-angle adjusting system has been constructed with a position actuator “inchworm” and a turntable; the former was fabricated from an electrostrictive unimorph and two electromagnets. The rotation angular velocity can be controlled by changing the voltage applied to the unimorph and the driving...

Description
Summary:A micro-angle adjusting system has been constructed with a position actuator “inchworm” and a turntable; the former was fabricated from an electrostrictive unimorph and two electromagnets. The rotation angular velocity can be controlled by changing the voltage applied to the unimorph and the driving frequency, and it has an angle step up to 6×10 -4 rad/step.
