SPIDER Automation JK42HS48-1684 NEMA 17 Stepper Motor | Permanent Magnet Stepper Motor | Precision Automation Actuator
Description
Power your precision machinery and automated setups with the high-performance SPIDER Automation JK42HS48-1684 NEMA 17 Stepper Motor. Because stepper motors move in precisely repeatable steps, they are the preferred choice for machines requiring exact position control. Operating as a brushless DC motor where service life depends on bearing durability, this reliable NEMA 17 motor provides 0.44 N-m of torque at 1.68A current per phase. Featuring a 48mm body length, a 1.8-degree step angle, a simple open-loop control mechanism that eliminates complex electronic circuitry, and a precision-machined round shaft designed for a secure grip with pulleys and drive gears, the SPIDER Automation JK42HS48-1684 ensures exceptional accuracy, reliability, and smooth response for demanding low-speed automation tasks.
Key Features
- NEMA 17 Compact Form Factor: Standard 42mm flange profile with a 48mm body length designed for tight mechanical layouts.
- Precise Step Accuracy: Offers a 1.8-degree step angle with high step accuracy (around 3% to 5% per step).
- Reliable Torque Output: Delivers 0.44 N-m of holding torque at 1.68A operating current per phase.
- Open-Loop Simplicity: Speed is directly proportional to input pulse frequency, keeping electronic control costs low without complex feedback wiring.
- Machined Round Shaft: Expertly turned round shaft profile designed to avoid slip or stall when paired with timing pulleys and gears.
Benefits
- Cost-Effective Control: Achieves absolute position repeatability without the high expense of complex closed-loop feedback systems.
- Smooth Dynamic Response: Exceptional starting, stopping, and reversing characteristics under standard step-pulse commands.
- Slip-Free Power Transmission: Precision-machined shaft profiles provide a secure grip with pulleys, drive gears, and timing belts.
- Long Operational Life: Quality-approved collection built with durable internal bearings for extended service reliability.
- Versatile Application Base: Ideal for low-speed, high-precision positioning across multiple manufacturing and hobbyist platforms.
Applications
- 3D Printers & Additive Manufacturing: Extruder and axis movement actuation.
- Compact CNC Routers & Mills: Precision table and spindle positioning drives.
- Camera Platforms & Gimbals: Smooth, repeatable mechanical panning and tilting rigs.
- XYZ Plotters & Engravers: High-accuracy coordinate drawing and cutting machinery.
- Laboratory & Automation Jigs: Custom mechatronic test fixtures and automated positioning slides.
