Measurement and evaluation on mechanical performances of standing-wave piezoelectric motor of V-shaped sandwich-type transducer having arc tip

•A home-made measured simple system for output performances of linear piezoelectric motors were constructed.•A prototype of SWUMs is manufactured and the mechanical characteristics were tested.•A basic measurement approach for service performances of linear ultrasonic motors was presented.•Static and dynamic performances of linear motor can be measured simultaneously in real time.
