2.0 N·m Integrated Stepper Motor 57mm Closed Loop

Overview

The iESSC57-36-20 is a 2.0 N·m Integrated Stepper Motor 57mm unit that pairs a 57 mm stepper motor with an integrated drive and a 1000 P/R incremental encoder in an 80 mm body length. The single-piece design removes the need for a separate driver and keeps the wiring short, which simplifies panel layout and reduces installation work.

How the Feedback Loop Works

The encoder reports shaft position to the integrated controller, which corrects the output in real time. Unlike a conventional stepper that only counts steps, this unit verifies that the shaft actually reached the commanded position, so positioning stays repeatable under changing load.

Torque and Heat

Holding torque is rated at 2.0 N·m, with a rated current of 5.0 A available to the drive stage. The controller limits heat generation during holding, and the low-vibration profile reduces mechanical stress on belts and couplings. Fast acceleration is supported by the closed loop response, which is useful for short-stroke indexing moves.

Key Specifications

• Frame size: 57 mm
• Body length: 80 mm
• Holding torque: 2.0 N·m
• Rated current: 5.0 A
• Feedback: 1000 P/R incremental encoder

Why the Integrated Design Reduces Work

This motor simplifies the machine builder’s work by combining the drive, motor, and encoder in one unit. There is no separate driver to size, mount, or tune, and the feedback loop is preconfigured to match the motor. For service teams, replacing one axis means swapping a single part rather than troubleshooting a drive-motor pair.

Applications

Typical installations include industrial automation, packaging machinery, robotics, and CNC machine tools where a compact 57 mm drive with closed loop control is required. It suits light feed axes, small indexing tables, and positioning mechanisms on multi-station machines.

Selection Considerations

Verify the 5.0 A supply requirement and the 80 mm body length against the layout. Because the drive is integrated, the thermal path goes through the frame; review duty cycle for continuous runs.
