These leads connect to the stepper motor through a removable JST-ZHR-5 connector. The motor 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=39351818092627\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e4 mm universal mounting hub\u003c\/a\u003e can be used to mount objects on the stepper motor’s 4 mm-diameter output shaft.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSize: 20 mm square × 30 mm, not including the shaft (NEMA 8)\u003c\/li\u003e\n\u003cli\u003eWeight: 60 g (2 oz)\u003c\/li\u003e\n\u003cli\u003eShaft diameter: 4 mm “D”\u003c\/li\u003e\n\u003cli\u003eSteps per revolution: 200\u003c\/li\u003e\n\u003cli\u003eCurrent rating: 600 mA per coil\u003c\/li\u003e\n\u003cli\u003eVoltage rating: 3.9 V\u003c\/li\u003e\n\u003cli\u003eResistance: 6.5 Ω per coil\u003c\/li\u003e\n\u003cli\u003eHolding torque: 180 g-cm (2.5 oz-in)\u003c\/li\u003e\n\u003cli\u003eInductance: 1.7 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\/SY20STH30-0604A.pdf?v=1622032390\" 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.
