2.0 N·m closed loop Stepper Motor With Brake – NEMA23, 76 mm, 5.0 A

Strong Torque-to-Length Ratio

The 57J1880EC-1000-LS-SCG is a 2.0 N·m closed loop Stepper Motor in a NEMA23 frame, with a 76 mm body and an integrated brake. Holding torque is 2.0 N·m at 5.0 A phase current, delivered on an 8 mm shaft. The 5.0 A rating gives it a strong torque-to-length ratio for its frame size, making it a balanced choice for machines that need NEMA23 torque in a moderate envelope.

Encoder Feedback and closed loop Behavior

An integrated 1,000 P/R encoder closes the position loop around the axis. When the load changes during a move, the drive compensates instead of accumulating error. At standstill the loop holds the position actively, which improves repeatability on machines with changing friction.

Brake Behavior

The integrated holding brake is released electrically before motion and engages when the drive is de-energized. This sequence protects the axis from unintended movement and is particularly important on inclined conveyors and vertical carousels.

Specifications

• Phase type: 2-phase bipolar
• Frame size: NEMA23 (57 mm)
• Body length: 76 mm
• Holding torque: 2.0 N·m
• Phase current: 5.0 A
• Shaft size: 8 mm
• Integrated encoder: 1,000 P/R
• Brake: integrated holding brake

Applications

Intended for motion control in CNC machine tools, desktop CNC systems, robotics, packaging machinery, factory automation, textile machinery, printing machinery, food processing, and automated handling mechanisms. The 76 mm body is a practical option where the full-length NEMA23 stack is too long but the shorter stacks lack torque. Common builds include belt-driven shuttle axes and lead-screw positioning stages where repeatability and holding torque are both important.

Practical Commissioning Advice

Enable the encoder as the position feedback source before running closed loop. Verify that the brake fully releases before the first motion command, otherwise the motor will draw excess current against a locked shaft and heat up quickly.
