Compact NEMA17 Stepper Motor — 3Pack (317HS130404S1) Key benefits Precise, lowpower motion: A 4lead bipolar stepping motor that delivers accurate positioning while drawing only 0.4 A per phase — ideal for applications with limited driver current or batterypowered systems. Solid holding torque in a compact package: Rated at 26 N·cm (36.8 oz·in), this motor gives reliable holding and stepping performance without a large footprint. Spaceefficient NEMA17 form factor: Identified as 42BYGH / NEMA17 with the 20mm body specification shown in the title, this motor combines the common 42 mm faceplate standard with a short profile to fit tight assemblies. Main features Model: 317HS130404S1 Quantity: 3 pieces per pack Motor type: 4lead bipolar stepping motor Mounting standard: NEMA17 (42 mm face) Rated holding torque: 26 N·cm (36.8 oz·in) Rated current: 0.4 A per phase Leads: 4wire configuration for bipolar driver compatibility Why this motor solves common problems Lower current requirement reduces heat and allows use with smaller drivers or lowercurrent driver settings without sacrificing step control. Short body/profile (20 mm reference in product title) helps when depth is limited — useful for compact printers, robots, or instrument panels where space is constrained. Standard NEMA17 mounting makes replacement and integration straightforward across many existing designs and kits. Compatibility and performance notes Designed to mount using standard NEMA17 hardware and footprint. 4lead wiring supports bipolar drivers for precise microstepping control. Rated current and holding torque should be matched to your driver settings and mechanical load for performance. Check your driver's current limits and microstepping settings when installing. Typical applications 3D printers and compact CNC or engraving machines where a short motor profile is required. Small robots, pan/tilt camera systems, and automated stages that need accurate positioning with low power consumption. DIY automation, pickandplace fixtures, or laboratory instruments that use NEMA17 motors but want a shorter motor body. What's in the box Three (3) x 317HS130404S1 NEMA17 stepper motors (4lead), rated 26 N·cm (36.8 oz·in) and 0.4 A per phase. Ordering details and use recommendations Confirm your driver supports a 4wire bipolar motor and can be set to 0.4 A per phase. Verify mechanical mounting depth and shaft coupling size in your design before installation. For quieter or higherresolution motion, use a microstepping driver and set current appropriately to match the motor's 0.4 A rating.
