JK42HS40 NEMA17 Stepper Motor – 4.2 kg-cm, D-Shaft

Description

The JK42HS40-1204AF-02 NEMA17 Stepper Motor is engineered to deliver precise and reliable motion, offering 4.2 kg-cm of holding torque at 1.2A current per phase. These motors are highly effective in applications demanding low speed with high positional accuracy, such as 3D printers, small-scale CNC routers, and robotic arms. Its inherent open-loop control mechanism eliminates the need for complex electronic feedback systems, making it a cost-effective and straightforward solution for precise automation.

Equipped with a machined D-type shaft, this stepper motor ensures superior grip with attached components like pulleys or drive gears, significantly reducing the risk of slippage or stalling during operation. The inclusion of a detachable 70cm cable further enhances its utility, providing flexibility and ease during wiring, installation, and subsequent maintenance or modifications. This design focuses on robust performance and user-friendly integration for various digital fabrication and automation setups.
