P-661, P-665 PIline™ OEM Ultrasonic Piezo Linear Motors

Product Description
PIline™-OEM Business in Motion
PIline™ P-661 and P-665 are the smallest piezo linear motor drives currently available on the market. In addition to being ultra-compact they also boast significantly higher drive and holding forces than conventional piezo motors.

Both versions incorporate a novel, ultra-small, high-speed ultra-sonic piezo-drive, developed and manufactured by PI and PI Ceramic. The ultrasonic piezo motor operating principle is based on the simultaneous longitudinal and transversal oscillation of a special piezoelectric ceramic plate, creating an elliptical motion at the ceramic tip.

Each cycle produces a tiny step, as small as a few nanometers, allowing continuous smooth motion with virtually unlimited travel when installed in an appropriate-length translation (or rotation) stage.

High Speed & Acceleration, Self-Locking
PIline™ piezo linear motors can be operated in any orientation. The lightweight, low-profile drive combines extremely high acceleration (up to 20 g) and velocity up to 800 mm/s with excellent position resolution and high holding forces. Since the ceramic tip of the motor is preloaded against the moving part of the stage, it creates a braking force while at rest. The benefits are the elimination of heat dissipation and servo dither (if used with a closed-loop system) in steady-state mode. Note that there will not be a position shift in holding mode, as is common with mechanical motor brakes! There are no gears, leadscrews or other mechanical components to contribute play or backlash.
