New Focus 8301NF Picomotor Piezo Linear Actuator 1/2 Motorized Micrometer #6
New Focus 8301NF Picomotor Piezo Linear Actuator 1/2 Motorized Micrometer #6. Clean used Newport / New Focus Picomotor motorized micrometer.
These use a piezoelectric actuator to provide precision rotation. Standard 9.5mm shank fits where manual micrometers would mount.
Unmarked, but appear to be 8301NF type. Tested here and guaranteed working. Picomotor actuators are ideal for motorizing fine-positioning stages and mounts for applications that require exceptional precision, small step sizes, and set-and-forget stability, all in a compact package. Picomotor actuators rely on the basic difference between dynamic and static friction. An example of this is the magician's "tablecloth trick, " in which a quick pull (low dynamic friction) of the cloth leaves the dishes on the table, while a slow pull (high static friction) would pull the dishes off the table and cause a big mess!
Our Picomotor actuator uses the same principle with a threaded jaw, similar to two halves of a split nut, clamped around a precision 80-pitch screw. One jaw is connected to one end of a piezoelectric transducer, and the other jaw is connected to the other end of the transducer. A slow electrical signal applied to the piezo slowly changes the length, causing the two jaws to slide in opposite directions. This slow sliding motion makes the screw turn (static friction). Because of the screws inertia and low dynamic friction, it remains motionless, holding its position.Simply reversing the order of the fast and slow signals reverses the direction of rotation. 0.5 (12.7mm) Travel. Maximum Speed: 1.2 mm/min. Drive Torque: 0.018 Nm. Rated Life: 1 x 10. Substantial 22 N axial load capacity. We take pride in our careful packing of delicate items.
