STEPPERONLINE Nema 14 0.9deg 8Ncm

The Nema 14 Stepper Motor 14RE07-1004VRN is a compact and precise bipolar stepper motor designed for applications where space is limited but high positioning accuracy is required. With a 0.9° step angle (400 steps/rev), it delivers finer resolution than standard 1.8° motors, making it ideal for 3D printers, precision instruments, robotics, and CNC equipment.

Despite its small size, this motor provides a holding torque of 8Ncm (11.33oz.in), ensuring stable performance in lightweight motion systems. Each phase draws 1.0A current, with a phase resistance of 3.9Ω and inductance of 2.5mH, making it efficient and easy to drive with most modern stepper motor controllers.

The motor has a Φ36.5mm frame (Nema 14), a body length of 17mm, and a 2.5mm diameter shaft (6mm length), making it highly suitable for compact mechanical assemblies. With a weight of only a few grams, it is perfect for projects that require lightweight yet reliable motion control.

The 4-wire bipolar configuration ensures compatibility with common stepper drivers, while the 500mm pre-attached leads make integration quick and convenient.
