3.5 N·m 36 VDC Stepper Motor with EtherCAT Fieldbus — Model iRSS60-36-35-17BC-RC/EC

Integrated Construction for Space-Constrained Cells

The iRSS60-36-35-17BC-RC/EC is a 3.5 N·m 36 VDC Stepper Motor delivered as an integrated closed loop unit in a 60 mm frame, rated at 3.5 N·m holding torque. It operates from 36 VDC at 5.0 A and supports RS485, CAN and EtherCAT fieldbus with a 17-bit absolute encoder. The motor carries its own drive, so the machine builder avoids a separate driver and its panel mount. This is especially useful in compact cells where several axes sit close together and cabinet space is limited; each axis needs only DC power and a fieldbus drop.

Fieldbus and Multi-Axis Operation

RS485 and CAN allow multiple units on one bus for synchronized cells, while EtherCAT gives the cycle-synchronous operation used by modern controllers. On-board closed loop control keeps the external PLC free from stepping logic, and the same hardware can serve legacy and modern control platforms by selecting the fieldbus at configuration time.

17-Bit Absolute Feedback

The 17-bit absolute encoder provides high-resolution position data that survives power-off, so axes restart at known positions. The closed loop corrects step loss during motion and holds position at standstill, which improves repeatability on fast-moving handling mechanisms. Because the unit runs from 36 VDC, current demand at 5.0 A is manageable with small power supplies, but the bus must still deliver peak current during acceleration.

Specification List

• Frame size: 60 mm
• Holding torque: 3.5 N·m
• Supply voltage: 36 VDC
• Rated current: 5.0 A
• Fieldbus: RS485 + CAN / EtherCAT
• Encoder: 17-bit absolute

Applications

Intended for factory automation, packaging machinery, robotics and CNC machine tools. In this torque class it handles small indexing tables, conveyor diverters and lightweight robotic axes. The 60 mm frame also fits compact precision equipment where absolute feedback and fieldbus control are required in a small envelope.

Commissioning Advice

Verify the 60 mm flange fits the axis and that the 36 VDC bus can supply 5.0 A peak during acceleration. Mount the unit with adequate airflow, and select the fieldbus variant that matches the controller before ordering.
