Product Details

Rotary LEGS® Rotary 80 mNm LR80

The LR80 is a compact, high torque, direct-drive piezoelectric rotary motor for friction drive without backlash.
Lack of gear-heads reduces the overall size so that LR80 often fits where other motors will not. In place, it delivers up to 80 mNm force and finds room in spaces too small for traditional motors.
When in the hold position no power is consumed. The LR80 motor is also capable of moving in full steps (waveform) or partial (microsteps).
Any 'move-and hold' application that requires high precision, instant response and low power consumption benefits from LR80’s Piezo LEGS® technology.

Features and Benefits

• Direct drive – Backlash free
• Microradian resolution
• No power draw in hold position
• Quick response
• Stainless steel motor
• Long service life

Product Application Information

The LR80 linear motor has been designed for use in a large range of applications, which is down to its high-speed dynamics and microradian resolution. Ideally suited for move and hold applications or automatic adjustments.


PiezoMotor is a world-leading developer and manufacturer of groundbreaking micro motors based on piezoelectric materials. Simple, precise and small, the motors replace traditional technology and enable motorisation where it was not possible before. The motors’ performance include subnanometre positioning and high force in a small package. The motors can operate in vacuum and can be made non-magnetic. In Uppsala, Sweden, PiezoMotor has its own in-house high-volume manufacturing facility, R&D centre and headquarters. All major geographical markets are covered by a global distribution network and many leading multinational companies.
