3.0 N·m Integrated Stepper Motor – 60 mm, 17-Bit Absolute Encoder, Fieldbus

The iRSS60-36-30-17BC-RC/EC is a 3.0 N·m Integrated Stepper Motor that combines a 60 mm closed loop stepper, its drive electronics, and fieldbus communication in a single housing. With a 17-bit absolute encoder, a 5.0 A rated current, and a 36 VDC supply, the unit is delivered as a complete axis-ready component for machine builders and automation integrators. Because the drive stage is mounted directly on the motor, the machine panel stays clear of per-axis drive modules, and the long shielded motor cable disappears from the design.

What an Integrated Fieldbus Unit Delivers

For a distributor-supplied automation solution, the main benefit of this construction is simplicity at the axis level. Each motor is wired with DC power and one fieldbus drop, and it is commissioned as a single component rather than a matched motor-driver pair. RS485, CAN, and EtherCAT are built in, so the axis can join existing control networks without pulse/direction converters. The on-board closed loop, driven by the 17-bit absolute encoder, corrects position error continuously during motion and holds position at standstill.

Position Retention After Power Loss

The absolute encoder stores the rotor position across power cycles. On packaging and handling lines, that removes the re-homing step after an interruption and keeps the process sequence intact, which shortens restart time and protects the machine cycle.

Key Specifications

Industrial Applications

The 3.0 N·m class suits vertical and horizontal axes in lightweight assembly cells, material handling equipment, packaging machinery, robotics, and CNC machine tools. The integrated construction is particularly attractive on multi-axis machines where cabinet volume and wiring labor are recurring cost drivers.

Selection and Commissioning Notes

Match the supply to 36 VDC and set the drive peak current to the 5.0 A rating. Because the drive shares the motor frame, plan for heat rejection through the mounting surface and keep airflow around the housing. When comparing this unit with a discrete stepper system, include the saved panel space, shorter wiring run, and lower parts count in the cost comparison.
