• Stepper motor - NEMA 11, 28²x45mm

This small stepper motor (28mm square) of 200 steps/revolution (i.e. a 1.8° step angle) has a weight of 140 g. It uses 4.5V at 670mA to create a torque of 950 g-cm. The 5 mm diameter D-shaft has been flattened by 0.5mm. The motor has four color-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver.
