Nema 17 Closed Loop Stepper Motor 65Ncm 2.1A with Magnetic Encoder 63.5mm for Precise Control

17HS242104ME1K Nema 17 ClosedLoop Stepper Electronic Starter Product overview This Nema 17 closedloop stepper electronic starter provides precise position feedback and reliable torque for compact motion systems. It combines a 65 Ncm holding torque rating with a magnetic encoder and closedloop control to reduce missed steps and improve repeatability in demanding applications. Key benefits Accurate motion: Magnetic encoder and closedloop operation detect and correct position errors in real time, reducing lost steps and improving repeatability. Reliable torque delivery: 65 Ncm holding torque and 2.1 A current rating support responsive, consistent motion for small machines and mechanisms. Compact form factor: Standard Nema 17 footprint with 63.5 mm thickness fits common mounts and saves space in tight assemblies. Simplified integration: Designed for systems that need a dropin Nema 17 solution with builtin closedloop feedback, reducing the need for external encoders. Stable performance: Closedloop feedback helps maintain smooth motion under changing loads and varying speeds. Key specifications Model: 17HS242104ME1K Frame size: Nema 17 Rated torque: 65 Ncm Rated current: 2.1 A Feedback: Magnetic encoder Body thickness (length): 63.5 mm Type: Closedloop stepper electronic starter Compatibility and fit Mechanical: Standard Nema 17 mounting pattern for easy replacement or upgrade of existing Nema 17 installations. Electrical: Suitable for systems and drivers that accept a 2.1 A stepper motor and closedloop feedback. Confirm driver compatibility with magnetic encoder signals before integration. Typical applications 3D printers: Improve layer registration and reduce print artifacts by closing the loop on motion axes that are prone to skipped steps. Compact CNC and milling machines: Maintain position under variable cutting loads, especially on small desktop or benchtop machines. Robotics and automation: Reliable actuation for jointed robots, pickandplace systems, camera sliders, and other precision mechanisms. What it solves Prevents cumulative position errors by monitoring actual shaft position and correcting deviations. Reduces downtime and calibration cycles caused by skipped steps in openloop stepper setups. Enables more compact designs by providing encoder feedback within a Nema 17 form factor. Installation notes Verify driver and controller support for the specific magnetic encoder interface used by the motor. Ensure power and current limits are compatible with the 2.1 A rating to achieve expected torque. Use standard Nema 17 mounting hardware and wiring practices for reliable operation. This 17HS242104ME1K closedloop stepper is suitable wherever precise, compact, and reliable stepper performance is required without adding separate encoder hardware.
