3.5 N·m closed loop Stepper Motor with RS485+CAN Fieldbus

The iESS60-36-35-17BC-RC is a 3.5 N·m closed loop Stepper Motor in a 60 mm frame with 5.0 A phase current on a 36 VDC bus, controlled over RS485+CAN. The driver is embedded in the motor housing, and a 17-bit absolute encoder provides closed loop feedback. It is supplied as a single-unit axis for indexing turntables, medium conveyors, and compact automation cells.

Torque in a Compact Frame

3.5 N·m from a 60 mm integrated unit is a practical match for indexing turntables and medium conveyors where a larger motor would be overkill. The single-unit package keeps the panel layout simpler and reduces the parts count on multi-axis machines.

RS485+CAN Control

Serial control over RS485 or CAN lets the machine controller manage speed, position, and diagnostics on the same wire pair. On multi-axis machines, bus addressing replaces individual pulse/direction wiring, and both physical layers are supported so the same axis can serve either controller type.

Specifications

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

Thermal Notes

The 5.0 A winding current plus the on-board drive heat means the 60 mm frame should be kept ventilated. Static torque of 3.5 N·m is the reference; continuous output depends on cycle rate and ambient temperature. For continuous operation, monitor the housing temperature and adjust the cycle rate if it approaches the maximum rating in the datasheet.

Applications

• Industrial automation
• Packaging machinery
• Robotics
• CNC machine tools

Selection and Setup Notes

Define the bus topology, node addresses, and baud rate before wiring the segment, and terminate the line correctly to avoid communication faults. Verify that the 36 VDC supply covers the 5.0 A peak current. The integrated unit is a good fit for retrofits where the existing panel has no room for a separate drive module, because the drive travels with the motor. Request the RS485 protocol document and mounting flange drawing from Lyenwsin.
