12 N·m Integrated Stepper Motor, 86 mm Frame with Encoder Feedback

Product Overview

The iHSS86-80-120 is a 12 N·m Integrated Stepper Motor on an 86 mm frame with a 156 mm body length. Motor and drive form a single assembly, and servo-style control is built into the digital stepper drive, giving the builder one package for high-torque closed loop axes. With the driver inside the motor housing, the machine no longer needs a separate drive module, and the interconnecting power cable is eliminated.

Servo Control within a Stepper Drive

An incremental encoder samples shaft position, and the integrated controller corrects the drive output in real time. The unit combines the holding behavior of a stepper with the correction loop of a servo, which improves positioning reliability on heavy loads and under speed changes. If a load spike threatens to stall the axis, the loop detects the deviation and compensates before a position error can build up.

Specification Summary

• Frame size: 86 mm
• Body length: 156 mm
• Holding torque: 12 N·m
• Rated current: 6.0 A
• Feedback: 1000 P/R incremental encoder

Torque and Thermal Notes

Holding torque is rated at 12 N·m at a rated current of 6.0 A, making the unit suitable for heavy positioning tasks such as machine tool axes and large indexing mechanisms. The drive is tuned to keep heat generation low, and the low-vibration profile protects the machine structure. Fast acceleration is available for demanding cycles, so the axis can reach speed quickly without losing steps.

Application Areas

The motor is used in factory automation, packaging machinery, robotics and CNC machine tools. In the 86 mm class it also handles textile machinery, printing lines and heavy material handling where a high-torque integrated stepper with encoder feedback replaces the cost and complexity of a full servo axis.

Sizing and Integration Notes

Verify the 86 mm flange and 156 mm body fit the machine, and confirm the 6.0 A supply can deliver peak current during acceleration. Check the torque-speed curve against the load at operating speed, and confirm the incremental encoder interface matches the controller. Lyenwsin offers application support to confirm this unit is the correct size for your axis.
