57J1880EC-1000-LS 2 Nm NEMA 23 Stepper Motor - Closed Loop

The 57J1880EC-1000-LS is a 2 Nm NEMA 23 Stepper Motor with closed loop feedback, providing 2.0 N·m holding torque from a 76 mm body, drawing 5.0 A per phase with an 8 mm shaft. The shorter stack keeps inertia low, which helps axes that accelerate and decelerate frequently in pick-and-place and printing work.

What the 1,000 P/R Encoder Adds

This is a closed loop stepper: the drive reads actual rotor position from the integrated 1,000 P/R encoder and compares it with the commanded position. If a step is lost, the drive corrects it rather than letting the error accumulate. For motion control applications, this removes the need to oversize the motor as a safety margin against stalling.

Thermal Management

Holding torque is specified at standstill with rated current. Under continuous running, the winding current governs heating. closed loop control lowers the standing current when the axis is idle, reducing temperature rise and letting the motor be mounted closer to heat-sensitive components.

Key Specifications

• Frame size: NEMA 23
• Body length: 76 mm
• Phase count: 2-phase
• Phase current: 5.0 A
• Holding torque: 2.0 N·m
• Shaft diameter: 8 mm
• Feedback: integrated 1,000 P/R encoder

Applications

Typical applications include CNC machine tools, packaging machinery, factory automation, precision robotic mechanisms, textile and printing machinery, food processing, and automated handling mechanisms. The 2.0 N·m rating is a balanced fit for light conveying, registration, and positioning axes in automated production.

Selection Considerations

Match the motor with a drive that supports the 1,000 P/R encoder and the 5.0 A phase current. Because the body is shorter than the 100 mm NEMA 23 variant, this motor suits compact mechanisms where a long stack would interfere with adjacent components. Verify the dynamic torque at your cycle speed to ensure the axis holds position under load. Also check the electrical interface of the drive and the encoder wiring, since correct shielding keeps the position signal clean in noisy industrial environments.
