Description
The JK42HS40-1204AF-02 NEMA 17 Stepper Motor is a reliable, high-precision motion control solution engineered for applications requiring repeatable and accurate positioning. Offering 4.2 kg-cm of holding torque at 1.2A per phase, this motor is a popular choice for 3D printers, CNC routers, mills, XYZ plotters, and camera platforms. It features a convenient 70cm detachable cable for streamlined wiring and easy maintenance. Designed with a precision-machined D-type shaft to ensure a secure, slip-free grip with drive components, this motor operates via a cost-effective open-loop control mechanism that eliminates the need for overly complex electronic circuitry.
Key Features
- Detachable Cable System: Includes a 70cm cable, allowing for rapid installation and effortless rewiring in your project.
- Precision Positioning: Rotation angle is directly governed by input pulses, with speed proportional to the pulse frequency for smooth motion.
- High Reliability: Provides excellent response to starting, stopping, and reversing commands with a step accuracy of 3% to 5%.
- Efficient Design: Simple open-loop control reduces total system costs by avoiding complex driver requirements.
- Robust Shaft: D-type shaft is machined to provide superior grip, minimizing the risk of stall or slip under load.
Important Operational Notes
- Dimensions and weight specifications are subject to a margin of error of ±2%.
- Proper mounting is required to minimize potential mechanical resonances.
- Not optimized for continuous operation at extremely high rotational speeds.
- Driver Recommendation: To provide the necessary current for stable operation, use drivers such as the TB6600 or DM542.
