Legs Linear LL06 Piezo Motor

6.5N stall force – Linear Actuator 

The Legs Linear LL06 Piezo Motor has direct drive with no backlash and can microstep in the sub-nano meter range. It weighs only 16 grams and has a stall force of 6.5N. It is available with built-in encoder.

Full force power-off locking is a safety function inherent to the design. A version of the motor, designed for vacuum and non-magnetic environments, is available.
