I have a lot of used NEMA 23 stepper motors in good working condition.
These are Automation Direct Sure Step STP-MTR-23079 Stepper Motors. 1.95Nm 1.8 deg step angle 200 steps per revolution.

I would be happy to give these motors away for free to someone in the UK (just pay postage) if they have a good use for them and are willing to send me a photo of them in use.

Please contact me for any further information or photos.
