Description
The JK42HS48-1204-20F NEMA 17 Stepper Motor is a high-performance solution engineered for applications requiring reliable, high-torque positional control. Delivering 5.6 kg-cm of holding torque at 1.2A current per phase, it is an ideal choice for 3D printers, CNC routers, mills, XYZ plotters, and professional camera platforms. The motor includes a 72cm detachable cable designed for rapid installation and maintenance; the motor-side features a connector, while the controller-side is left open for custom soldering or terminal connections. Featuring an open-loop control mechanism and a precision-machined D-type shaft, this motor ensures smooth, slip-free performance and simple, cost-effective system integration.
Key Features
- Convenient Connectivity: Includes a 72cm detachable cable, simplifying wiring and enabling fast, efficient assembly or replacement.
- High-Torque Output: Optimized to provide 5.6 kg-cm of holding torque, suitable for demanding low-speed, high-precision tasks.
- Precision Control: Step angle and movement are directly dictated by input pulses, with speed scaling proportionally to pulse frequency.
- Cost-Efficient: Designed for open-loop control, significantly reducing the complexity and cost of required electronic control circuitry.
- Robust D-Type Shaft: Engineered to provide a secure, reliable grip for pulleys and drive gears, preventing common stall or slip issues.
Important Operational Notes
- Dimensions and weight specifications are subject to a margin of error of ±2%.
- Proper mounting and alignment are recommended to avoid mechanical resonances.
- Not designed for continuous operation at extremely high rotational speeds.
- Cable Wiring: The motor-side has a connector, while the controller-side of the cable is open for soldering.
