Picomotor actuators are ideal devices for motorizing fine-positioning stages and mounts in optical or mechanical systems. Use them with optomechanical translation stages or custom devices. They have better than 30-nm resolution with minimal backlash, and can exert a 5-lb (22-N) force. Moreover, they have exceptional longterm stability and the ability to hold their position with no power applied. These last two features make the Picomotor actuators unique among motion-control devices and ideal for typical set-and-hold applications. Such applications include precision control of sample holders inside cold and/or vacuum chambers, hands-off adjustment of hard-to-reach mirror mounts, or adjustments of optical mounts that are sensitive to forces applied while twisting a knob (for instance optimizing the alignment of a laser cavity or adjusting the pointing of a beam over a long distance).The standard sized shanks of the Models 830X and 12X0.5-mm threading of the Models 832X let them fit into standard micrometer mounting holes. The Tiny Model 8353 gives you a solution for even the smallest application. For rotation without translation, use the Model 8341NF rotating shaft.Use these Picomotor actuators with our Model 8742 Open-Loop Picomotor Controller/Driver or Model 8743-CL Closed-Loop Picomotor Controller/Driver.Contact us for custom configurations and volume pricing.
Our Tiny Picomotor actuator is a smaller-sized version of our standard Picomotor actuators. We have improved the design so that it will meet even more of your compact-area needs. The Tiny Picomotor actuator is ideal for moving small linear stages, like our Compact Gothic-Arch-Bearing stage. It is also integrated with some our our Pint-Sized mounts. The overall footprint is even smaller now; the cable exits from the side, similarly to our standard Picomotor actuators. For such a small device, it has an impressive pushing force. The maximum load for the Tiny Picomotor actuator is now 3 lbs (13 N).We have also introduced a vacuum-compatible version of the Tiny Picomotor, the Model 8353-V . It is designed for environments down to 10-6 Torr. It's perfect for moving small optics and stages in your vacuum chambers.With two mounting options, a standard 0.25" shank and a 1/4-40 thread version, it is straight-forward to incorporate it into your design. The Tiny Picomotor Actuator should be used with the 8742 controller/driver or our TTL/Analog Picomotor driver.
The Model 8310 closed-loop Picomotor piezo actuator and Model 8743-CL Intelligent closed-loop Picomotor driver are ideal for applications where closed-loop control and position calibration is required. With an integrated rotary encoder and forward and reverse limit switches, this unique device offers the best attributes of the standard Picomotor actuator<30-nm resolution, >5 lbs (22 N) of force along with set-and-forget long-term stabilitywith the added beneﬁts of exceptional accuracy and ±1-µm bi-directional repeatability over the entire half-inch travel range.Choose between operating the Model 8310 closed-loop Picomotor actuator in closed-loop mode where it can hold a set position, or command it to move a speciﬁed distance. You can also choose between position- or velocity-proﬁled movement. Either way, when the actuator reaches its target location, the controller will adjust the motor to the precise requested encoder count and then stop motion. Even if you keep the servo loop enabled, the motor will only move in response to any system disturbances which cause rotation of the screw. Because the inherent resolution of the motor is ﬁner than the resolution of the encoder, zero-count encoder error is always achieved. You can query the encoder to determine the rotation of the screw at any time.Use the Model 8310 closed-loop Picomotor actuator with our Model 8743-CL Intelligent Closed-Loop Picomotor controller/driver. Our modular iPico drivers and controllers provide the ability to build a system incorporating multiple standard Picomotor actuators and one or more closed-loop Picomotor actuators at the same time on the same control network. The Model 8743-CL controller/driver controls one Model 8310 closed-loop Picomotor actuator. You can control up to 31 Model 8743-CL drivers with the from a computer via Ethernet or USB.The Model 8743-CL Intelligent Closed-Loop Picomotor controller/driver includes a USB stick with companion software, the manual, and example programs in LabVIEW enabling you to get up and running quickly. The provided GUI allows you to test and use an actuator network without doing any programming. Adding the Model 8758 Hand Control Pad provides an option for stand-alone operation without use of a computer.The closed-loop Picomotor actuator can be integrated into most of our opto-mechanical mounts and is compatible with our translation stages.
