It is designed for CNC machines and other motion-control equipment that requires higher torque than a typical NEMA 17 stepper motor. The motor operates at 4 A per phase and uses open-loop positioning control driven by input pulses.\u003c\/p\u003e\u003cp\u003eEach input pulse determines the motor's rotation angle, while pulse frequency controls speed. The motor is suitable for applications requiring repeatable starting, stopping, reversing, and position control. The machined D-type shaft provides a positive drive interface for components such as pulleys and gears.\u003c\/p\u003e\u003cp\u003eFor product support or application questions, contact customer service at \u003ca href=\"https:\/\/robotdoo.com\/\"\u003erobotdoo.com\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eNEMA 23 hybrid bipolar stepper motor for CNC machines and motion-control applications\u003c\/li\u003e\n\u003cli\u003e30.61 kg-cm holding torque at 4 A per phase\u003c\/li\u003e\n\u003cli\u003e1.8° step angle for incremental positioning\u003c\/li\u003e\n\u003cli\u003eFour-lead design\u003c\/li\u003e\n\u003cli\u003eD-type shaft for pulley and gear drive components\u003c\/li\u003e\n\u003cli\u003ePulse-based control for repeatable starting, stopping, reversing, and positioning\u003c\/li\u003e\n\u003cli\u003eOpen-loop operation without complex feedback circuitry\u003c\/li\u003e\n\u003cli\u003eMotor speed is proportional to input pulse frequency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eJK57HS112-3004-03\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotor type\u003c\/th\u003e\n\u003ctd\u003eNEMA 23 hybrid bipolar stepper motor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShaft type\u003c\/th\u003e\n\u003ctd\u003eD type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStep angle\u003c\/th\u003e\n\u003ctd\u003e1.8°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupply current\u003c\/th\u003e\n\u003ctd\u003e4 A\/phase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNumber of leads\u003c\/th\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInductance\u003c\/th\u003e\n\u003ctd\u003e3.6 mH\/phase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRotor inertia\u003c\/th\u003e\n\u003ctd\u003e480 g-cm2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHolding torque\u003c\/th\u003e\n\u003ctd\u003e30.61 kg-cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDetent torque\u003c\/th\u003e\n\u003ctd\u003e0.68 kg-cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStep angle accuracy\u003c\/th\u003e\n\u003ctd\u003e±5%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInductance accuracy\u003c\/th\u003e\n\u003ctd\u003e±20%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResistance accuracy\u003c\/th\u003e\n\u003ctd\u003e±10%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShaft diameter\u003c\/th\u003e\n\u003ctd\u003e8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShaft length\u003c\/th\u003e\n\u003ctd\u003e20.6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e57 x 57 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOverall dimensions (L x W x H)\u003c\/th\u003e\n\u003ctd\u003e112 x 57 x 57 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCable length\u003c\/th\u003e\n\u003ctd\u003e0.3 m (30 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e1690 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eSuitable for CNC milling machines, CNC routers, and other equipment requiring higher-torque stepper motor drive and repeatable open-loop position control.\u003c\/p\u003e\u003ch2\u003eOperating Notes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eResonance may occur as a result of improper installation.\u003c\/li\u003e\n\u003cli\u003eOperation at extremely high speeds is not recommended.\u003c\/li\u003e\n\u003cli\u003eDimensions and weight may have a ±2% tolerance.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Robot Pi Shop","offers":[{"title":"Default Title","offer_id":48260354146534,"sku":"SM-000015-DVR","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0954\/0326\/files\/JK57HS112-3004-03-NEMA-23-3061-kg-cm-Hybrid-Bipolar-Stepper.jpg?v=1788167850","url":"https:\/\/robotdoo.com\/products\/jk57hs112-3004-03-stepper-motor","provider":"RobotDoo","version":"1.0","type":"link"}
