NEW PRODUCT – Stepper motor – 200 steps/rev, 12V 350mA! A stepper motor to satisfy all your robotics needs! This 4-wire bipolar stepper has 1.8° per step for smooth motion and a nice holding torque. The motor was specified to have a max current of 350mA so that it could be driven easily with an Adafruit motor shield for Arduino (or other motor driver) and a wall adapter or lead-acid battery.

Some nice details include a ready-to-go cable and a machined drive shaft (so you can easily attach stuff). We drove it with an Adafruit motor shield for Arduino and it hummed along nicely at 250 RPM.

• 200 steps per revolution, 1.8 degrees
• Bipolar stepper, requires an H-bridge!
• 4-wire, 12 inch leads
• 42mm/1.65″ square body
• 31mm/1.22″ square mounting holes, 3mm metric screws (M3)
• 5mm diameter drive shaft, 24mm long, with a machined flat
• 12V rated voltage (you can drive it at a lower voltage, but the torque will drop) at 350mA max current
• 28 oz*in, 20 N*cm, 2 Kg*cm holding torque per phase
• 35 ohms per winding
