Compact Linear Stage with Ultrasonic Piezomotor


Fast, Self-Locking, and Silent

Ultrasonic piezomotors are small, fast, and inexpensive. They are especially suitable for applications with low operating cycles and can also be integrated into mobile measuring and medical devices. Due to their self-locking, the target position does not have to be held by additional brakes or electrical currents as in the case of magnetic drives.

Featured Facts

PI Expands its Technological Spectrum


Air bearings are essential for nanometer precision motion with extremely high velocity stability over long travel ranges. In contrast to mechanical guides, the air bearing enables the moving platform to glide over a layer of air with almost no friction at all. This means that no hysteresis or backlash occurs and when combined with linear motors, it is possible to reach very high velocities.

Above all, air bearings ensure excellent guiding accuracy, which means straightness and flatness of motion well below one micrometer. PI has implemented on dual motor axis of PIglide HS Planar XY stage an active yaw control algorithm. Y-Axis and Yaw Axis have separate control loops for linear and rotational motion control.
