Oriental Motor VEXTA AlphaStep ASM69BAE Stepper Motor. Dual 8mm Shaft. 2.9V, 2.1A. 60mm frame size (can probably be adapted to NEMA 23). I have no detailed specs, but certainly torquey given its weight and size.
Weight is ~3 lbs, case depth is ~96mm. Connector is plug and play with AlphaStep controllers.
Condition: Good used condition. I have two units for sale, photos are representative.
