2.0 N·m 36 VDC Stepper Motor – Integrated closed loop Unit with 17-Bit Absolute Encoder

The iESSH60-36-20-57-17BC-RC/EC is a 2.0 N·m 36 VDC Stepper Motor with an embedded driver, a 17-bit absolute encoder, and closed loop control in a 60 mm housing. Rated at 5.0 A and carrying RS485+CAN or EtherCAT fieldbus, it is delivered as one orderable part instead of a separate motor and drive pair. This packaging matters on multi-station lines where the motor-driver cable length and the panel area used by drives both grow quickly with each axis.

Why Integration Matters on Multi-Station Lines

On printing and textile lines with many axes, the motor-driver cable length and the panel area used by drives both grow quickly. This unit moves the drive to the point of motion, which shortens power wiring and frees cabinet space for the PLC and safety components.

Fieldbus Variants

RS485+CAN and EtherCAT options are available. For food processing and battery-equipment cells where machines are frequently reconfigured, the absolute encoder also removes the homing step after a format change.

Specifications

• Frame size: 60 mm
• Holding torque: 2.0 N·m
• Supply voltage: 36 VDC
• Rated current: 5.0 A
• Fieldbus: RS485 + CAN / EtherCAT
• Encoder: 17-bit absolute
• Control: closed loop

Load and Environment

Treat 2.0 N·m as the static rating; the continuous value depends on ambient temperature and cycle rate. The compact, low-vibration construction suits precise indexing mechanisms where overshoot would waste cycle time.

Applications

• Packaging machinery
• Industrial automation
• Precision robotic mechanisms
• Textile machinery
• Printing machinery
• Food processing
• Automated handling mechanisms
• Precision positioning mechanisms for battery equipment

Selection and Setup Notes

Check that the 36 VDC supply holds the 5.0 A peak current and that bus termination matches the protocol chosen. If the line runs continuous indexing, confirm the duty cycle against the thermal budget of the frame. The closed loop feedback keeps the axis repeatable through format changes, and the absolute encoder preserves position across power cycles, which shortens restart time after every stop.
