NEMA 23 JK57HS76-2804 Stepper Motor 1.8° 1.89N·m 2.8A (57x57x76mm)

The NEMA 23 JK57HS76-2804 Stepper Motor is a high-performance bipolar stepper designed for demanding motion-control applications. With a 1.8° step angle and a rated holding torque of 1.89 N·m (≈267 oz·in), this 57 mm square frame motor (76 mm body length) delivers precise positioning, smooth operation and reliable torque for CNC, 3D printers, robotics, automation, and industrial equipment. The motor features a robust steel housing, a 6.35 mm (¼\") shaft, and a 4-lead configuration for straightforward bipolar driver compatibility.

Features:

• High Holding Torque: Rated torque 1.89 N·m for strong holding and low resonance in stepped motion.
• Standard NEMA 23 Frame: 57 x 57 mm flange for easy mounting to standard brackets and couplers.
• Precise Step Angle: 1.8° per step (200 steps/rev) for accurate positioning and microstepping performance.
• Robust Construction: Durable steel body and precision shaft (Ø 6.35 mm) for long service life.
• Bipolar 4-Lead Wiring: Simple to wire with common stepper drivers (A+/A–, B+/B–).
• Optimized for Drivers: Rated current 2.8 A/phase; works well with current-limited stepper drivers (e.g., DRV8825, TB6600, DM542).
• Compact but Powerful: 76 mm body length balances torque and compact footprint for space-constrained systems.

Package Includes:

1 x NEMA 23 JK57HS76-2804 Stepper Motor (1.89 N·m, 1.8°, 2.8 A, 4-lead)
