• 3 phase, NEMA23 frame size
• 56 mm long
• 3.5 A phase current
• 0.8 N.m holding torque
• 6.35 mm shaft size
• Built with high quality materials.High precision, low motor heating, and low vibration。
The 57J1250-635 is a three-phase open-loop stepper motor rated at 0.8 N.m of holding torque at 3.5 A per phase. Its 56 mm body is among the shortest in the NEMA23 class, making it a sensible choice for light-duty positioning where mounting depth is limited.
Three-phase excitation reduces torque ripple, giving smooth, low-noise stepping appropriate for food and packaging line accessories where operators work close by. The 3.5 A winding keeps heating moderate, so torque stays stable through repeated index cycles.
The 6.35 mm shaft is sized for small couplings and pulleys. Open-loop control means no encoder wiring or tuning. The NEMA23 flange provides a simple, widely available mount.
This motor is well suited to motion control across Packaging Machinery, Factory Automation, desktop CNC setups, robotics, Textile Machinery, Printing Machinery, Food Processing, and Light-Duty Handling and Positioning Mechanisms.
Select a 3-phase drive rated for at least 3.5 A. For lightweight, repetitive positioning this motor offers a compact, low-maintenance open-loop solution that is easy to wire and run.
