P6.8 - Ultrasonic Piezoelectric Motor with Intrinsic Torque Measurement – First Results

P. P. Pott, S. Matich & H. F. Schlaak
In many technical applications the actual torque provided by an actuator is of interest. Torque sensing, however, tends to be costly and complex. When it comes to small-sized high-torque but low velocity actuation systems ultrasonic piezoelectric actuators can be used. Here, high power density and noise-less operation can be provided. Here, we present an ultrasonic piezoelectric motor with intrinsic force sensing capabilities that provides high power density, high torque and a signal linearly correlated to...
