A 3-axis LNR50DD 2" travel stage shown with the manual adjusters replaced by DRV250 actuators.
The DRV250 offers 50 mm (1.97") of travel and a unidirectional repeatability of ±1.6 μm. When used with one of our stepper motor controllers, the DRV250 achieves a theoretical minimum step size of 2.4 nm and a maximum speed of 50 mm/s.
The hybrid stepper motor, with its rotor that consists of 50 individual magnetic teeth, is ideally suited for micro-stepping applications. Aside from the increase in resolution resulting from increasing the steps per revolution from 200 to 409 600, micro-stepping also ensures smoother low-speed motion by allowing the discrete 1.8° step size to be reduced to much smaller steps, resulting in lower vibrational noise.
The DRV250 stepper motor drive is equipped with a trapezoidal screw thread for more efficient high-load operation than is available from a standard threading.
This actuator is compatible with our 2" TravelMax Manual Stages. To use the DRV250 with these stages, mount the motor to the side of the stage using two 40 mm long M4 cap screws (included). In order to secure the TravelMax stage to a table while using the DRV250 actuator, the LNR50P4(/M) base plate is required.

(posted 2021-08-27 13:23:46.94) I'm a graduate student who is trying to build a custom stage with a controller and parts I already have in the lab. I was wondering the compatibility of this actuator (DRV250) with a controller I already have (Sutter MP 285). I have the pin-out for the Sutter's driver and I am comfortable with creating custom wiring but want to make sure I of compatibility before purchasing anything. cwright
(posted 2021-09-02 09:25:24.0) Response from Charles at Thorlabs: Thank you for your query. Unfortunately we are not able to support the use of third party controllers with our actuators and would recommend the use of BSC201 with the DRV250. wmwu
(posted 2016-02-29 19:00:04.997) Dear Officer,
Is "Stepper Motor Drive (DRV014)" able to connect to the "Translation Stage(PT1A)", and to control its motion?
Thanks very much.
Best regards, Alan bwood
(posted 2016-03-01 04:06:43.0) Response from Ben at Thorlabs: Thank you for your feedback. Unfortunately, the DRV014 is not compatible with the PT1A. Among other reasons, the DRV014 barrel size is too large (Ø12 mm) for the PT1A (Ø9.5 mm). The recommended stage to pair with the DRV014 are the 50 mm TravelMax™ stages, and the recommended actuators for the PT1A can be found under the "Actuator" tab on the PT1 series web page. |

Thorlabs' PIA50 Piezoelectric Inertia Actuator provides high-resolution linear motion control with a long piezo-controlled translation range in a compact package. It can support loads up to 2.5 kg (5.51 lbs) and preloads up to 25 N with typical movements of 20 nm and no backlash. The step size can be adjusted up to 30% to a maximum of approximately 30 nm using the KIM101 Controller and Kinesis® software. However, due to the open-loop design, piezo hysteresis, and application conditions such as the direction of travel, the achieved step size of the system can vary by up to 20% and is not normally repeatable. An external feedback system will need to be used to overcome this variance.
This actuator has a Ø3/8" (Ø9.525 mm) barrel that can be mounted in a manual stage that has a Ø3/8" mounting clamp. For compatibility with 1/4"-80 threaded mirror mounts see our 10 mm travel piezo inertia actuator. The actuator is self-locking when at rest and when there is no power supplied to the piezo, making the actuator ideal for set-and-hold applications that require nanometer resolution and long-term alignment stability. Manual adjustments can be made using the knob on the adjuster screw, as long as the piezo is not actively translating the screw; the knob is also compatible with 5/64" (2.0 mm) hex keys.

The control cable can be adjusted up to 110° for space-constrained applications.
Powered by a 10 mm long discrete piezo stack, the actuator can operate at speeds of up to 3.5 mm/min. The design of the piezo motor will rotate the tip of the lead screw during translation. For information on the design of our piezo inertia "slip-stick" motor actuators, please see the complete presentation here.
Required Controller
A K-Cube Piezo Inertia Controller is required to operate our PIA50 Piezo Inertia Actuator; the actuator cannot be operated using a standard piezo controller. The K-Cube controllers have an internal sawtooth voltage signal generator capable of sending sub-millisecond pulses (steps) with controllable amplitudes from 85 V to 125 V. In addition to a single-channel driver, we offer a four-channel driver capable of single- or dual-channel operation, which is ideal for applications involving multiple motorized actuators, such as beam steering.
For more information, please see the full web presentation.
