Rotary Piezo Motor 2,5 mNm / 9 mm / 50V

Piezo Motion RAS series piezo rotary motor with a plain hollow shaft. The motor has a driving torque greater than [gt]2.5 mNm.

Piezo Motion piezomotors work on a patented principle of excitation of ultrasonic standing waves within a piezoelectric resonator. The resulting superposition of two orthogonal ultrasonic waves causes eliptical movement of the resonator tip which direct drives a rotary or linear element.

Unfortunately Piezo Motion went out of business

We are sorry but this product is no lnger available
