The ZFS25B actuator is a component of the LNR25ZFS Translation Stage.
The ZFS series of motors has 24 full steps per revolution, and when driven by the KST101 drivers, there are 2048 microsteps per full step, giving 49,152 microsteps per revolution of the motor. The output shaft of the motor goes into a 400:9 gear head. This requires the motor to rotate 44.445 times to rotate the 1.0 mm pitch lead screw one revolution. The end result is the lead screw advances by 1.0 mm.
Linear displacement of the lead screw per microstep:
Number of Microsteps x Gearbox Ratio = 49,152 x 44.445 = 2184560.64
The linear displacement of the lead screw per microstep is
1.0 mm / 2184560.64 = 0.46 x 10-6 mm = 0.46 nm

The ZST225B Actuator provides smooth, precise linear motion control in a package measuring 150.5 mm (5.93") in length. Powered by a small-diameter, dual-phase stepper motor, this actuator operates at speeds of up to 2.0 mm/s. The non-rotating drive tip reduces wear and friction and improves smoothness of motion by removing rotational contact at the tip. Mounting is via a standard Ø3/8" (Ø9.525 mm) barrel.
This actuator uses a stepper motor that provides sufficient torque for loads up to 40 N (8.99 lb). It allows very small step sizes over the entire travel range, delivering greater flexibility with low (<15 µm) backlash and fine resolution. The design incorporates a 41:1 gear reduction head which, when combined with the 49,152 microsteps per revolution offered by the KST101 stepper motor driver, gives a theoretical travel per microstep of 0.5 nm (see the Calculations tab for details).

Each member of the ZST200 series of motors has 24 full steps per revolution, and when driven by the KST101 drivers, there are 2048 microsteps per full step. Hence, there are 49,152 microsteps per revolution of the motor. The output shaft of the motor goes into a 40.866:1 gear head. This requires the motor to rotate 40.866 times to rotate the 1.0 mm pitch lead screw one revolution. The end result is the lead screw advances by 1.0 mm. To calculate the linear displacement of the actuator per microstep, use the following:
Linear displacement of the lead screw per microstep:
Number of Microsteps x Gearbox Ratio = 49,152 x 40.866 = 2,008,645.63
The linear displacement of the lead screw per microstep is
1.0 mm / 2,008,645.63 = 0.49 x 10-6 mm = 0.5 nm

 (posted 2015-04-24 16:12:26.65) Please provide details on designing the mating part to best press fit the actuator mounting the part. Thank you. bhallewell
 (posted 2015-04-27 10:41:06.0) Response from Ben at Thorlabs: Thanks for your request here Ruby. This is dependent upon the size of the acceptance bore of the particular stage you would intend to mount this actuator to. To mount the stage into a 0.5" hole we hold the item RBA1 an adapter which would encompass the 3/8" barrel on the actuator.
I will contact you directly to discuss this. martien.veekens
 (posted 2015-03-11 13:53:36.193) Dear Mrs./Mr.
To add these parts in our systems we need some more information. We could not find it in the available datasheets.
Can you inform me about the materials and surface treatments of the below mentioned parts.
ZST225B
NRT150/M
LNR50SE/M
LNR50S/M
Thanks in advance for your help. bhallewell
 (posted 2015-03-16 11:40:47.0) Response from Ben at Thorlabs: Thank you for your request for this information. I will contact you directly to see if I can clarify surface detail to wihtin your requirements. mszheng
 (posted 2014-09-20 12:23:38.257) I have a brand new ZST225B that becomes scalding hot once plugged in, without any load or movement at all. It is on default settings. This appears to be a defective unit, can you replace it for us? msoulby
 (posted 2014-09-22 08:43:29.0) Response from Mike at Thorlabs: Our older model of TST001 and stepper actuators have a different current settings which are set in the APT Config utility. We will contact you directly to learn more about your configuration settings as if these are set incorrectly you could inadvertently supply the incorrect moving and rest currents to the motor causing it to overheat. hamid.jahroudi
 (posted 2014-08-04 11:32:48.177) Hello
I need an actuator for moving in 266 nm steps and with constant velocity and minimum error.
I saw "Calculated Minimum Incremental Motion" section but I'm worried about backlash of this apparatus.
Overally, can I use this apparatus for my Goal?
I'm grateful for your help.:) msoulby
 (posted 2014-08-05 05:47:52.0) Response from Mike at Thorlabs: The calculated minimum increment is a calculation based on the microstep count of the stepper motor when driven with our TST001 controller. In reality the actual minimum incremental will be much larger than the 0.5nm calculated; this is due to friction, load, mechanical slack in the system and backlash. The actuator is however very capable of moving a very low velocities and sub-micron increments. Our software also has built in backlash correction to compensate for any predictable errors to improve the repeatability of the actuator, this setting can be adjusted by the user or even disabled if necessary. michael.renner
 (posted 2014-05-14 16:20:49.24) Is it possible to fit the actuators to the 10mm barrels of the metric stages (PT3/m) somehow? cdaly
 (posted 2014-05-22 11:36:38.0) Response from Chris at Thorlabs: It's is not possible to take an existing PT3/M and replace the micrometers with these actuators, but it is possible for us to provide a custom which uses these. Due to the barrel size (10mm) of the metric micrometer used in the standard PT3/M, the hole is to large for the standard 3/8" actuators barrels. This would be possible with the other metric version of the stage though, which do not eed to have the larger hole, such a PT3A or PT1B. |

The DRV225 Trapezoidal Stepper Motor Drive offers 25 mm (0.98") of travel and a unidirectional repeatability of ±1.6 μm. When used with one of our stepper motor controllers, this actuator can achieve 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 microstepping applications. Its 200 full steps per revolution are further broken down into 409 600 microsteps. In addition to the resulting increase in resolution, microstepping produces smoother low-speed motion by allowing the discrete 1.8° step size to be reduced to much smaller steps with inherently lower vibrational noise.
The DRV225 stepper motor drive is equipped with a trapezoidal screw thread for more efficient high-load operation than is available from standard threading.
This actuator is compatible with our 2" TravelMax manual stages. To use the DRV225 with these stages, mount the motor to the side of the stage using two 40 mm long M4 cap screws (included).

The stepper motor used in the DRV225 actuator has 200 full steps per revolution of the motor. Each full step is broken down into 2048 microsteps. There are 409,600 microsteps per revolution of the motor when using the BSC201 controller. The leadscrew has a pitch of 1.0 mm, meaning that it will produce 1.0 mm of linear motion per revolution. The linear displacement of one actuator microstep can be calculated as follows:
1.0 mm per Revolution / 409,600 Microsteps per Revolution = 2.4 x 10-6 mm per Microstep
To calculate the linear displacment for a full step, substitute 409,600 microsteps per revolution with 200 full steps per revolution.

Our Z8 Series Motorized Actuators are engineered for use with optical positioning devices. They offer high resolution in a lightweight package, which makes these actuators ideally suited for demanding optical laboratory automation applications. The Z825B delivers 25 mm of travel and has been designed as a replacement for the Z725 motor.
Commercial limit switches have been added to provide overdrive protection and accurate home positioning. The motor in the Z8 provides a motion velocity of 2.3 mm/sec. The precision of the encoder (512 counts/rev) results in a minimum resolution of about 29 nm.
The Z825B has been designed specifically to replace the manual adjusters in stages and mirror mounts that have a Ø3/8" (Ø9.525 mm) barrel clamp, like the PT1 Single-Axis Translation Stage or the PT3 Three-Axis Translation Stage.
To install, remove the existing manual adjuster from the mount, and fit the replacement Z8 Actuator. The photo below shows a PT3 three-axis stage with a Z825B fitted to one of the axes.
The units are shipped with 1.6' (0.5 m) of cable. A 2.5 m (8 ft) extension cable (PAA632) is available separately.
For applications with different travel requirements, please see our 6 mm Z806 and 12 mm Z812 actuators. We also offer the Z825BV vacuum-compatible version (sold below), which is rated for use down to 10-6 Torr and is shipped with a 1.6' (0.5 m) flat ribbon cable, IDC connector, and a converter cable for use with our KDC101 controller.
The KDC101 DC Servo Controller is the required driver for the Z8 series actuators. Please note that previous generation TDC001 units will require a firmware upgrade to V1.0.10 or later, before they can be used with the Z8 series motors. An upgrade is included with the latest APT Server software, which can be downloaded here.
For the Z825B, there are 512 encoder counts per revolution of the motor. The output shaft of the motor goes into a 67:1 planetary gear head. This requires the motor to rotate 67 times to rotate the 1.0 mm pitch lead screw one revolution. The end result is the lead screw advances by 1.0 mm.
The linear displacement of the actuator per encoder count is given by
512 x 67 = 34,304 encoder counts per revolution of the lead screw,
whereas the linear displacement of the lead screw per encoder count is given by
1.0 mm / 34,304 counts = 2.9 x 10-5 mm (29 nm).

 (posted 2018-06-07 15:19:34.433) Hi, I am using Z825B and the KDC101 to control. I can understand the calculation process and the resolution. But how could I know how many rotating steps (number on KDC101 display) corresponding to the real distance moving by one direction? For example, if I change the control number from 0 to 0.25 on KDC, what will be the real distance moving by the Z825B induced? Thanks rmiron
 (posted 2018-06-11 05:53:03.0) Response from Radu at Thorlabs: I am afraid that I do not know what is the number on KDC101's display that you are referring to. By default, the controller only displays the current position in mm or degrees and the reading should be labelled accordingly. Therefore, no conversion should be necessary. I will contact you directly for clarification purposes. Javier

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, hysteresis, and application conditions, the achieved step size of the system can vary by up to 20%. 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.
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 KIM001 or KIM101 controller is required to operate our PIA25 Piezo Inertia Actuator; the actuator cannot be operated using a standard piezo controller. These drivers have an internal sawtooth voltage signal generator capable of sending sub-millisecond pulses (steps) with controllable amplitudes from 85 V to 125 V. The KIM001 and KIM101 controllers offer one and four output channels, respectively.
For more information, please see the full web presentation.

This Apiezon grease has excellent anti-seize properties. It contains PTFE for maximum lubricity and is ideal for re-lubricating the lead screw threads of our ZST, ZFS, and Z8 series actuators described above. It is supplied in a syringe for easy application and is recommended both for general use and for vacuum applications down to 10-9 Torr. It has an optimal working range of 10 to 30 °C (50 to 86 °F).
Note: It is recommended that the lead screws of the Z8, ZFS, and ZST motors are lubricated every 50,000 cycles or 6 months, whichever comes first.
