Stepper motor for robotics projects

This Adafruit bipolar stepper motor provides 200 steps per revolution at 1.8 degrees per step for precise motion control. It operates at 12V with a maximum current of 350mA and delivers 28 oz*in holding torque. The 4-wire design includes a ready-to-use cable and machined drive shaft for easy mechanical attachment.

Thermal and electrical characteristics

Each winding presents 35 ohms of resistance at the rated 12V supply. The motor draws up to 350mA per phase during normal operation and was tested running smoothly at 250 RPM with an Adafruit motor shield. The 42mm square body dissipates heat through its aluminium frame without active cooling.

Sustained load behaviour

Under continuous operation the motor maintains its 20 N*cm holding torque per phase while driven by two full H-bridges. The 5mm diameter shaft with 24mm length and machined flat resists slippage during prolonged use. Mounting holes spaced at 31mm accept M3 screws for secure installation in fixed positions.

Questions about this item

How do I wire the four leads to an Adafruit motor shield?

Connect the wires in this order: Red, Yellow, skip the ground pin, Green, Brown (or Gray). The Red and Yellow pair is coil 1; the Green and Brown or Gray pair is coil 2.

Will the machined flat on the 5 mm shaft wear out and need replacement?

The flat is machined into the 24 mm long drive shaft for a secure coupler fit. It does not wear under normal use, so the motor itself does not require scheduled shaft maintenance.

At what speed does torque drop off when running continuously at 12 V?

The motor was tested at 250 RPM with an Adafruit motor shield and ran smoothly. Torque will fall as speed rises beyond that point because winding inductance limits current at higher step rates.
