NEMA 17 Stepper Motor – 4.2kg·cm Holding Torque Bipolar 180 degree
Command absolute micro-stepping precision in your automated machinery using the premium NEMA 17 4.2kg·cm Stepper Motor. Explicitly engineered to meet the high-torque, zero-backlash constraints of modern spatial layouts, this high-performance bipolar hybrid motor delivers a precise 1.8-degree step angle (200 discrete steps per revolution). Inside its rugged, high-strength alloy shell sits a high-density permanent magnet rotor matrix wrapped in low-resistance pure copper windings, ensuring immense 4.2kg·cm (58.3 oz-in) holding torque with minimal thermal sagging during continuous operation. It features a standard D-shape output shaft to prevent component slippage and standard 4-wire termination paths, making it the definitive hardware component choice for constructing DIY 3D printers (RepRap, Ender), desktop CNC routers, high-accuracy laser engravers, and automated medical pipetting arms driven by A4988, DRV8825, or TMC2209 silent stepper drivers
