Piezo motor drives

27 April 2014

The properties of piezo motor drives, which include self-locking when powered down, compactness and zero jitter, make them suited to applications where power consumption, space constraints or precision are critical. As such the drives have been used in photonics alignment work, battery operated metrology instrumentation and microscopy to name but a few.

A range of different piezo motor technologies are manufactured by PI, including ultrasonic, stick slip and stepping drives. The piezo material used in each design is produced by the PI group ensuring a quality and reliability of supply which is critical for the many industrial users of the technology. Each technology involves controlled contact between two ceramic surfaces.

The drives are available as OEM components, as an open loop linear or rotary positioner or as a closed loop system including encoder feedback, controller and software.
