3.5 N·m Integrated Stepper Motor – 36 VDC, With EtherCAT and 17-Bit Encoder

The iESSH60-36-35-17BC-RC/EC is a 3.5 N·m Integrated Stepper Motor that packs drive, motor, RS485/CAN/EtherCAT fieldbus, and a 17-bit absolute encoder into a 60 mm housing. Running from 36 VDC at 5.0 A, the unit is delivered as a complete axis-ready component, which makes it a practical choice for machine builders who want closed loop performance without the footprint of a separate drive in the cabinet.

Integrated Drive for Compact Machines

This iESSH-R/RC/EC unit removes the separate drive stage from the control cabinet. Each 60 mm axis needs only DC power and a bus cable, which is valuable in machines with dense axis layouts where panel space is at a premium. Maintenance is also simpler because each axis is a single replaceable unit.

Bus Control Options

RS485, CAN, and EtherCAT are supported, letting the axis join both simple serial networks and synchronized EtherCAT systems. The closed loop runs on the unit, so the external controller handles motion commands rather than stepping pulses.

Feedback and Positioning

The 17-bit absolute encoder provides fine resolution and preserves shaft position across power cycles, avoiding re-homing. closed loop correction of step loss keeps the axis accurate in fast indexing applications where torque margins are limited.

Specifications

• 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
• Control mode: closed loop

Applications

Used in industrial automation, packaging machinery, robotics, and CNC machine tools. The 3.5 N·m class covers lightweight robotic axes, diverters, and indexing mechanisms in compact cells where the integrated package keeps the mechanical layout simple.

Installation and Thermal Notes

Confirm the 36 VDC bus can deliver the 5.0 A peak current. Because the drive shares the motor frame, provide airflow or metal mounting for heat transfer, and avoid enclosures that trap warm air around the housing.
