3.0 N·m 57 mm Integrated Stepper Motor with Encoder

Product Overview

The iHSS57-36-30 is a 3.0 N·m 57mm Integrated Stepper Motor with a 100 mm body length. The driver is contained in the motor housing, and the digital stepper drive implements servo-style control with encoder feedback for real-time position correction. For CNC and robotics builders, this means a full closed loop axis that mounts like a standard stepper and wires like a single component.

closed loop Behavior

Position feedback from a 1000 P/R incremental encoder lets the controller verify that the shaft reached its commanded position. The loop corrects any deviation immediately, so the axis stays accurate under load changes and during fast acceleration. This verification also removes the torque derating that open-loop steppers need as a safety margin against missed steps.

Key Specifications

• Frame size: 57 mm
• Body length: 100 mm
• Holding torque: 3.0 N·m
• Rated current: 4.0 A
• Feedback: 1000 P/R incremental encoder

Torque and Thermal Notes

Rated at 3.0 N·m holding torque and 4.0 A, the unit covers typical automation axis loads. The drive is tuned for low heat generation, and the low-vibration characteristic protects precision mechanisms while fast acceleration shortens cycle times. The 4.0 A draw keeps the supply requirement modest, simplifying the machine’s electrical design.

Applications

The motor is applied in factory automation, packaging machinery, robotics and CNC machine tools. In the 57 mm NEMA 23 class, it also fits desktop CNC, motion control tables and precision robotic mechanisms where closed loop feedback protects repeatability. Distributors recommend this model when a machine needs servo-like reliability at stepper pricing.

Selection Guidance

Verify the 57 mm flange and 100 mm body fit the machine, and confirm the 4.0 A feed against the bus. Check the torque-speed curve for the operating point and confirm the encoder interface with the controller.
