This NEMA 14-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 500 mA at 10 V, allowing for a holding torque of 1 kg-cm (14 oz-in). The motor has four colour-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. Our 5mm universal mounting hub can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft, and our NEMA 14 aluminium bracket offers a variety of options for mounting this stepper motor in your project. Specifications * Size: 35 mm square × 28 mm, not including the shaft (NEMA 14) * Weight: 140 g * Shaft diameter: 5 mm “D” * Steps per revolution: 200 * Current rating: 500 mA per coil * Voltage rating: 10 V * Resistance: 20 Ω per coil * Holding torque: 1 kg-cm (14 oz-in) * Inductance: 13.5 mH per coil * Lead length: 30 cm * Output shaft supported by two ball bearings Dimensions The following diagram shows the stepper motor dimensions in mm. The dimension labelled “length” is 28 mm. The output D-shaft has a length of 21 mm and a 5 mm diameter with a section that is flattened by 0.5 mm. This shaft works with our 5 mm universal mounting hub.
