4.5 N·m Integrated Absolute Stepper Motor (iRSS86-60-45-17BC)

Mid-Range Torque in a Sealed Integrated Package

The iRSS86-60-45-17BC is a 4.5 N·m Integrated Absolute Stepper Motor that offers 4.5 N·m holding torque from an 86 mm frame with the drive mounted on the motor. The short 80 mm body keeps the axis compact, which is useful when several modules are stacked in a machine frame.

Real-Time Error Correction via 17bit Encoder

Feedback from the 17bit absolute encoder is sampled every 50 microseconds, letting the drive correct position deviations as they occur. This closed loop behavior reduces missed steps and keeps motion smooth at low and medium speeds. The absolute encoder also retains position across power cycles, so the machine can resume without a homing routine.

Built for Harsh Process Areas

An IP67 rating lets the motor operate where dust, moisture, or washdowns are present, without relocating the drive to a protected cabinet. Low heat and low vibration support continuous-duty indexing, and the sealed construction protects the electronics from contamination.

Why the Sealed Integrated Design Matters

The drive-on-motor architecture saves panel space and reduces the amount of shielded cabling a machine needs. Because the drive and motor are sealed together, the unit can be placed in the process area rather than inside a cabinet, which shortens the distance to the driven mechanism and simplifies the machine layout.

Applications

Industrial automation, packaging machinery, robotics, and CNC machine tools are the main applications, where absolute position retention and a sealed drive-on-motor architecture reduce machine complexity. The compact body makes it a fit for index tables, capping turrets, and small rotary stations.

Selection Considerations

Verify the 6.0 A supply requirement and the 80 mm body length against your machine layout. Because the drive is sealed in the frame, allow airflow around the unit for continuous duty. Our technical team can help confirm the torque requirement and provide cable and connector options.
