8.5 N·m Stepper Motor with Encoder, 86 mm Integrated Unit

Introduction

The iHSS86-80-85 is an 8.5 N·m Stepper Motor With Encoder supplied as an integrated unit in an 86 mm frame with an 118 mm body. It merges the driver into the motor housing and applies servo-style control on a digital stepper drive, simplifying the axis package while keeping closed loop positioning. For production machinery that runs continuously, the single-housing design also means fewer cables to route and less chance of a loose connection.

Feedback and Correction Loop

An incremental encoder provides position feedback, and the controller applies real-time error correction to the step output. This reduces step loss during fast motion and improves repeatability when the load changes between cycles. The loop also keeps the motor from over-heating at standstill, because the drive reduces current once the axis settles into position.

Specification List

• Frame size: 86 mm
• Body length: 118 mm
• Holding torque: 8.5 N·m
• Rated current: 6.0 A
• Feedback: 1000 P/R incremental encoder

Torque and Operating Behavior

Rated at 8.5 N·m holding torque and 6.0 A, the unit delivers consistent output for medium and heavy automation loads. Low heat generation supports continuous operation in enclosed frames, while low vibration and fast acceleration suit cyclic movement. The 118 mm body keeps the package shorter than the 12 N·m version, which helps on machines where length is limited but torque still matters.

Where It Is Used

Applications include CNC machine tools, packaging machinery, factory automation, precision robotic mechanisms, textile machinery, printing machinery, food processing and automated handling mechanisms. Distributors commonly recommend this torque class for textile and printing registration rollers that need steady, repeatable feed motion all day.

Selection Notes

Confirm the 86 mm flange and 118 mm body length fit the machine, and size the DC bus for 6.0 A peak draw. Compare the available torque at the required feed speed, not just the holding rating. Lyenwsin can supply the full datasheet and help you verify that this integrated unit meets the duty cycle.
