PILine® Ultrasonic Piezomotors

Small, High-Speed and Cost-Efficient

  • Silent operation through control frequencies in the ultrasonic range
  • Cost-efficient drive principle: One actuator, one control phase
  • Easy mechanical integration, compact design
  • Self-locking at rest: No holding currents, no heating at stop, no energy consumption and no control jitter
  • Holding force up to 15 N
  • Velocity to 500 mm/s
  • Resolution to 1 nm
Ultrasonic Piezomotor


PILine® ultrasonic piezomotors are small, high-speed and cost-efficient. Ideally suitable for applications of low operating cycles, they can also be integrated as drive into mobile measuring and medical devices. Due to their self-locking, the target position does not have to be held via additional brakes or electrical currents as in the case of magnetic drives.
