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

The iRSS60-36-30-17BC-RC/EC is an integrated closed-loop stepper motor with a 60 mm frame, 3.0 N·m holding torque and a 5.0 A rated current on 36 VDC. RS485, CAN and EtherCAT fieldbus are built in, together with a 17-bit absolute encoder. All drive electronics live in the motor housing.

Drive-plus-motor in a 60 mm package

This unit combines the driver stage with the motor, so panel space and cabling are reduced on every axis. For a machine with several 60 mm axes, the saving in wiring, connectors and cabinet volume is significant, and maintenance is simplified because each axis is a single replaceable unit.

Bus control and on-board loop

With RS485, CAN and EtherCAT, the axis joins existing control networks without pulse/direction converters. The closed loop runs inside the unit, using the 17-bit absolute encoder to correct position error continuously.

Feedback and position retention

The absolute encoder stores position across power cycles, eliminating re-homing on start-up. In packaging and handling lines, this shortens restart time after a power interruption and keeps the process sequence intact.

Specifications

• Frame size: 60 mm
• Holding torque: 3.0 N·m
• Supply voltage: 36 VDC
• Rated current: 5.0 A
• Fieldbus: RS485 + CAN / EtherCAT
• Encoder: 17-bit absolute

Applications

Built for factory automation, packaging machinery, robotics and CNC machine tools. The 3.0 N·m class suits vertical and horizontal axes in lightweight assembly and material handling cells.

Engineering notes

Match the supply voltage to 36 VDC and set the drive peak current according to the 5.0 A rating. Because the drive is integrated, thermal design of the mounting panel is part of the system design. See the datasheet for torque-versus-speed curves to select the right gear ratio for your load.
