4.5 N·m Integrated closed loop Stepper Motor for Fieldbus Automation (iHSS86-60-45-RC/EC)

Machines built around networked axes often struggle with cabinet space long before they run out of torque. The iHSS86-60-45-RC/EC addresses that by housing the driver electronics inside an 86 mm motor enclosure, creating a 4.5 N·m Integrated closed loop Stepper Motor that connects directly to RS485, CAN, or EtherCAT networks.

Integrated Construction Reduces Axis Footprint

By moving the drive out of the cabinet and onto the motor, this unit removes a separate drive module from the control panel. The remaining wiring is a DC feed and a network drop, which is a significant simplification on packaging lines and CNC machines where several axes sit close to the process. Service access also improves because each axis is an independent, replaceable module.

Fieldbus Communication for Coordinated Motion

Fieldbus communication makes this motor part of a networked, coordinated machine. On CNC machine tools it powers auxiliary axes that talk to the PLC over EtherCAT for clock-synchronized motion. Packaging lines use it on folder, sealer, and indexing stations where the RS485 or CAN bus shares setpoints across many axes. Factory automation systems can coordinate any axis into an overall motion plan, and precision robotic mechanisms use the closed loop for repeatable joint positioning. Textile and printing machinery run guider rolls and tensioning axes, while food processing and automated handling mechanisms use the networked control for synchronized conveyors and diverters.

Encoder Feedback for Position Security

The built-in 1000 P/R incremental encoder feeds rotor position back to the drive every control cycle. closed loop correction compensates for load variation and helps prevent step loss, making the axis more predictable during frequent starts, stops, and reversals.

Three Protocol Options on One Motor

RS485, CAN, and EtherCAT interfaces are selectable, so the same mechanical mounting can serve different machine lines. This flexibility simplifies stocking and lets a single design cover both simple PLC networks and real-time EtherCAT systems.

Specification Summary

• Frame size: 86 mm
• Holding torque: 4.5 N·m
• Rated current: 6.0 A
• Supply voltage: 60 VDC
• Feedback: 1000 P/R incremental encoder
• Communication: RS485, CAN, EtherCAT

Selection Considerations

This 4.5 N·m rating sits between light-duty 60 mm units and the higher-torque 86 mm models, making it a good fit when an axis needs more force than a 60 mm frame provides but does not require the top end of the 86 mm range. Confirm the 60 VDC bus voltage matches the machine supply and allow airflow around the housing for continuous operation.
