The LEGS® Piezo Technology is a perfect match for linear OEM motion solutions
Exceptional size to force ratio
Few components result in compact motors and actuators. The exceptional size to force ratio makes the LEGS® Piezo Actuator Technology a great fit for OEM engineering challenges.
True linear motion simplifies engineering
No need for gears, spindles or mechanical transmissions. Engineers achieve the linear direct drive with few mechanical parts.
Vacuum capable and non-magnetic
The option of motor housings in non-magnetic alloys and ceramic drive units results in motors with a magnetic flux density lower than 1 nT at 10mm distance. They do not generate magnetic fields or are affected by magnetic fields. No problem in an MRI machine or in cellular applications.
Extreme precision – all the way down to sub nanometer resolution
The motors can easily position down to sub-nanometer levels if needed. The electronics is the limiting factor, not the motor.
Response Time and High-Speed Dynamics results in rapid and precise positioning
Piezo motors are renowned for their exceptional response times and high-speed dynamics, which make them ideal for applications requiring rapid and precise positioning. Their fast response is driven by the direct action of piezoelectric elements, which can change shape within microseconds when electrical voltage is applied. This results in minimal inertia and allows for very high acceleration and deceleration rates. These motors can achieve nanometer-level precision in motion control and maintain stability even at high speeds, making them indispensable in fields like microscopy, semiconductor manufacturing, and optics.
Speed and step length
The speed of the motor is depending on step length and drive frequency. The indicated maximum speed on the product pages is in normal environment and for continues operations.
Under intermittent conditions and with specific controllers, you can greatly increase the speed. Contact us for further information. The environment and payload heavily affect the step length.
Self-locking without power, no backlash and zero drift
They achieve linear motion without gears or ball screws. The motor reacts instantly both in starting and stopping. The friction locks the drive rod in place without any power draw.
Precision guiding and integrated encoders
Most models are available with integrated encoder and precision guiding.
