The Next Generation of Sub-Micron Precision Has Arrived

Meet the New Piezo LEGS® Linear 6N Motor

new Piezo LEGS Linear 6N - LL06 motor

MICROMO is pleased to announce the release of a new direct drive linear motor with integrated encoder – Piezo LEGS® Linear 6N, also called LL06.

High Precision Motion in a Compact Space for OEM Applications

This new motor is the next generation of the classic Piezo LEGS®. The motor has undergone major redesign and repackaging, with the same piezo ceramic actuators at its core as the popular predecessor, LL10. The basic performance characteristics are therefore unchanged, but now with a slimmer design and options for guides that steer the drive rod, and an integrated high resolution optical encoder.

"The LL06 represents a milestone for PiezoMotor - a new motor generation which is designed to meet customer demand for compact size and integration of a high resolution position sensor, and competitive in price so that it can replace conventional stepper motor and lead screw assemblies in many OEM applications." - Johan Westermark, CEO of PiezoMotor.

The slimmer basic design allows for integration in even tighter spaces. The non-encoder version motors can be stacked with a center-to-center distance of only 7 mm. Weight has also been reduced by 30% with a total weight of only 16 grams (including guides and encoder). Plastic guides to steer the drive rod improve the repeatability of the motor and make integration into customers' systems easier. The integrated incremental position sensor with 1.25 µm resolution allows closed loop control, saving valuable space as there is no need for bulky external encoder systems.

Applications Using Piezo Technologynew piezo LL06 without sensors

Piezo LEGS® linear motors are intended for a large range of OEM applications with focus on precise positioning. The direct drive principle of these motors ensures motion without mechanical play or backlash. Sub‑micrometer movement down to nanometer level can be achieved with a compact and strong motor. Piezo LEGS® motors can replace conventional stepper motor assemblies when there is need for better resolution, smoother linear movement or only to save valuable installation space.

Motors based on Piezo LEGS® technology are ideally suited for move and hold applications since they are stiff by design and do not consume any power when in hold position. The drive technology is direct, meaning no gears or lead screws are needed to create linear motion. Speed ranges from nanometers per second to millimeters per second, and can be seamlessly controlled in the whole dynamic range.

The Piezo LEGS® technology is characterized by its outstanding precision, fast response and settling time and low power consumption. These benefits, along with nanometer capabilities, provide a unique advantage in the market.
