The 57J1880-450 is a 2.2 N·m NEMA23 Stepper Motor, a 2-phase 57 mm-frame motor, 80 mm long, rated 2.2 N·m at 5.0 A with an 8 mm shaft. It is a balanced, mid-duty option within the frame for general motion control tasks.
At 2.2 N·m the motor drives belt drives, lead screws and light rotary mechanisms used in robotics and desktop CNC. The 5.0 A winding keeps torque responsive while the 8 mm shaft matches widely available hardware.
In robotics the motor positions lightweight joints and turntables with repeatable stepping; in desktop CNC it covers axis drives with adequate margin for small cutters. Packaging machinery uses it for indexing and registration tasks where the compact length eases mounting in crowded frames. Its 80 mm body also fits retrofit projects where the original NEMA23 motor was longer.
Precise rotor-stator geometry lowers vibration and audible noise, supporting clean motion in sensitive applications. Reduced vibration also helps the axis hold tolerance longer, as less energy is transmitted into couplings and leadscrew nuts.
With 2.2 N·m available, this motor is most effective at low to medium speeds, which covers typical indexing and feed work. If the application requires sustained high-speed running, check the torque-speed curve carefully and consider a longer body or a closed loop option from the same range.
Match a 5.0 A-capable driver and provide cooling. Standard NEMA23 pattern keeps deployment straightforward across a machine family. Confirm the coupling bore for the 8 mm shaft and review the torque-speed curve at the operating RPM, since torque falls as speed rises. Lyenwsin can supply the motor, a matched drive and wiring to shorten project lead times.
