New NEMA 17 stepper motor with optional integrated lead screw

We have added a compact, powerful new NEMA 17-size stepper motor to our wide selection of stepper motors. This 42×38 mm stepper motor is available with a standard 5 mm D-shaft for general-purpose use, but perhaps more exciting is the version with a 28 cm threaded rod, which turns it into a linear actuator capable of precision open-loop position control. This latter version has the stainless steel lead screw built right into the stepper motor, so there is no need to deal with extra hardware such as shaft couplers and set screws, and the copper alloy traveling nut with mounting holes is included. Raise your next project to new heights with the precision (40 µm per full step) and control of a stepper motor!

Please see the product pages for more information:

What motor driver are you using for the animation? Do you have a low voltage, high current stepper driver? Thanks.
For the animated GIF, we used our DRV8825 Stepper Motor Driver Carrier, High Current. If you are looking for a low-voltage stepper motor driver, you might consider our DRV8834 carrier, which can handle the same amount of current as the DRV8825, but operates from 2.5 V to 10.8 V.

Looking for such a leadscrew motor with a 3/8" (or 9/10mm) 20 tpi screw, 80 oz motor. Anything available?

PS theres no useful info on these ads about the ***leadscrew** and its critical, only stating the motor torque and thread dimensions is meaningless without stating the leadscrew efficiency factor (0.0xx in*lb/lb force). The single most important piece of info is missing.

Good price!
Sorry, retracting the "good price" comment. $29.99 with a longer leadscrew on line on Banggood.
Hello, Davec.

The NEMA 17 stepper motor with a 28 cm threaded rod is the only stepper motor with lead screw that we currently carry. We are looking into the efficiency factor you mentioned; do you have examples of places that specify it?

Hello, what is the thrust rating for this configuration? I assume the thrust produced by a load on the lead screw is NOT transferred to the motor and that there are internal bearing. What is the trust rating for these bearings?
Hello, Jan.

The datasheet for the stepper motor, which can be found under the "Resources" tab on the product page, gives a maximum axial force of 10N. Our expectation is that the axial load rating already takes any such bearings into account, making it equivalent to a linear force rating.
