Product Announcements: Piezoelectric Motors

DTI has developed a novel low voltage, high torque, rotary motor technology based on ultrasonic piezoelectric principles. The motor can be controlled using either digital or analog controllers. Moreover, DTI's piezomotors have intrinsic high resolution together with high torque. These features provide a simplified design in which a gear-head/gearbox can be eliminated altogether.

DTI's ultrasonic piezoelectric linear motors are designed based on a single-piece piezoceramic element allowing the use of low-cost high-volume production methods. The resonant nature of excitation of the piezoelement facilitates greater speed and energy efficiency. (read more)

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. (read more)

While there are several types of piezomotors on the market, the design and technology employed by DTI in its piezomotors is quite unique and provides certain key advantages in both use and manufacturability. Furthermore, DTI's piezomotors offer a unique solution for both rotary and linear piezomotor application requirements. (read more)

Novel drives allow semiconductor-related positionoing systems to be developed with very high accuracy and reliability. (read more)

Piezo motor specialist PI introduces the new M-272 linear shaft motor actuator based on a maintenance-free ultrasonic ceramic motor. (read more)

The M-663 Piline™ piezo motor stage is the smallest closed-loop ultrasonic linear piezomotor-driven translation stage with linear encoder (100 nanometer resolution). It combines the advantages of piezo-motor drives with PI precision micro mechanics.

PI offers miniature open-loop ultrasonic linear motor driven stages as small as ~9x6x2 mm (model P-652). (read more)

The superior performance characteristics of the new piezomotor over the EM based system yields significant advantages in stabilized platform applications where high resolution, short response time, smoothness of motion and low drift are important. (read more)

Evaluation kits provide a valuable tool for those interested in learning more about the performance and operation of DTI's piezomotors. Each kit contains a piezomotor, driver board (for manual & external control), cables, power supply and instruction manual. (read more)
