Lower current reduces both torque and temperature rise, and lower voltage decreases torque (optimal range: 12–24V DC). Widely used in 3D printers, DIY robots, CNC machines, and other automated systems, the 42mm Stepper Motor offers compact size and high torque for tough tasks.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43357951033553,"sku":"BW-B0FHHW54DD","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/61smDLb-g5L._SL1500.jpg?v=1790987647","url":"https:\/\/belmontwarehouse.com\/products\/nema-17-stepper-motor-42x60mm-0-84nm-118-95oz-in-2-3a-1-5%cf%89-bipolar","provider":"Belmont Warehouse","version":"1.0","type":"link"}
