This is a placeholder topic for “Stepper Motor with 18cm Lead Screw: Bipolar, 200 Steps/Rev, 42×38mm, 2.8V, 1.7 A/Phase” comments.
This NEMA 17-size hybrid bipolar stepping motor has an integrated 18 cm (7″) threaded rod as its output shaft, turning it into a linear actuator capable of precision open-loop positioning. The included traveling nut has four mounting holes and moves 40 µm (1.6 mil) per full step; finer resolution can be achieved with microstepping. The stepper motor has a 1.8° step angle (200 steps/revolution) and each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in).Read more
Can you provide speed control electronics for pololu stepper motors?
The speed of the motor is controlled by the delay between steps. Shorter = faster.
This would normally be done at software/code level, links to drivers are in the product description.
You should be able to do what graham is sugesting with any microcontroller and the addition of a driver board like the DRV8825
Not to mention you could also plug these directly into most hobby CNC machines, or 3D printer boards.
Does Core stock the different shaft lengths of this motor?
We do carry a few different lead screws the Lulzbot Lead Screw can be found here. The Makeblock lead screw can be found here
