The Nema 23 CNC Stepper Motor JK57HS76-2804 is a high-performance, industrial-grade stepper motor engineered for CNC routers, CNC mills, 3D printers, plasma cutters, laser machines, robotics, automation systems, and precision motion applications in Bangladesh. With a strong 1.89N.m (19.2kg-cm) holding torque, this motor delivers stable, accurate, and repeatable movement for demanding mechanical loads. Designed with a hybrid stepping structure, it offers smooth motion, fast response, and superior efficiency for professional and hobby CNC setups.

Features:

• Heavy-duty Nema 23 hybrid stepper motor ideal for CNC machinery and industrial motion control

• High torque output delivering 1.89N.m / 19.2kg-cm holding torque at 3A per phase

• 1.8° precise step angle for accurate positioning and motion control

• Excellent response to start, stop, and reverse pulses from stepper motor drivers

• Supports high mechanical loads with strong radial and axial force tolerance

• Durable construction with high insulation resistance (100MΩ min at 500VDC)

• Capable of operating in wide ambient temperatures from -20°C to +50°C

• Designed for stable performance under continuous operation

• Suitable for CNC upgrades, replacement motors, heavy-load axes, and industrial automation

How to Use:

• Connect the motor to a compatible stepper motor driver rated for 3A per phase

• Mount the motor securely on CNC or mechanical assemblies using Nema 23 standard mounting holes

• Match the wiring with A+ A- B+ B- connections for accurate coil pairing

• Tune microstepping and current settings on the driver for optimal torque and noise performance

• Ensure proper shaft alignment to avoid excessive radial or axial load

• Use flexible couplings or timing pulleys appropriate for 8mm shaft diameter

• Provide adequate ventilation or cooling in heavy-duty continuous applications
