Each phase draws 670 mA at 4.5 V, allowing for a holding torque of 950 g-cm (13 oz-in). 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.\u003c\/p\u003e\n\u003cp\u003eOur \u003ca href=\"\/en-eu\/products\/pololu-universal-aluminum-mounting-hub-for-5mm-shaft-m3-holes-2-pack?variant=39351818027091\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e5 mm universal mounting hub\u003c\/a\u003e can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSize: 28 mm square × 45 mm, not including the shaft (NEMA 11)\u003c\/li\u003e\n\u003cli\u003eWeight: 140 g (5 oz)\u003c\/li\u003e\n\u003cli\u003eShaft diameter: 5 mm “D”\u003c\/li\u003e\n\u003cli\u003eSteps per revolution: 200\u003c\/li\u003e\n\u003cli\u003eCurrent rating: 670 mA per coil\u003c\/li\u003e\n\u003cli\u003eVoltage rating: 4.5 V\u003c\/li\u003e\n\u003cli\u003eResistance: 6.8 Ω per coil\u003c\/li\u003e\n\u003cli\u003eHolding torque: 950 g-cm (13 oz-in)\u003c\/li\u003e\n\u003cli\u003eInductance: 4.9 mH per coil\u003c\/li\u003e\n\u003cli\u003eLead length: 30 cm (12″)\u003c\/li\u003e\n\u003cli\u003eOutput shaft supported by two ball bearings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMore specifications are available in the \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/SY28STH45-0674A.pdf?v=1622209208\" target=\"_blank\" rel=\"noopener noreferrer\"\u003edatasheet\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003eDimensions\u003c\/h2\u003e\n\u003cp\u003eThe following diagram shows the stepper motor dimensions in mm.
