H391(39mm)- 1.8° per step, 2/4 Phase
I.CH
Nema 16 Stepping Motor
Our NEMA 16 Stepper Motor delivers accurate angular positioning and smooth rotation, ideal for applications demanding tight motion control. Built with a durable stator and rotor design, it offers reliable performance with low vibration and noise, even in continuous operation. With its compact footprint, this motor fits seamlessly into space-limited setups. It is widely used in 3D printers, CNC routers, small robotic arms, precision medical devices, and automated labeling machines. Engineered for consistent torque output across low-to-moderate speeds, it meets the needs of both industrial automation and hobbyist projects.
