Rotary ultrasonic piezomotors

DTI’s ultrasonic piezoelectric rotary motors are divided into two types depending on size and design construction, these are referred to as the Piezo Rhino™ and Piezo Beetle™ series.

The Piezo Rhino™ (big, powerful, fast and precise) series incorporate a unique (patents pending) combined rotary piezoresonator technology enabling a substantial increase in the coupling efficiency between the stator and the rotor. This, together with the fact that the piezomotor is a resonance motor, substantially increases the overall motor efficiency, providing simultaneously superior resolution and torque. 

The Piezo Rhino series includes a wide range of powerful bidirectional (reversible) and unidirectional models, including a range of novel pcb-mounted piezomotors.

The Piezo Beetle™ (small, agile and powerful) series are unique (patents pending) miniature ultrasonic rotary piezomotors offering sizes (O.D.) below 10 mm. These motors are based on a single composite piezoelement-pusher component utilizing a novel excitation method in which bidirectional rotation is achieved using a relatively compact and inexpensive design.
