4.5 N·m Integrated closed loop Stepper Motor – 60 VDC, 17-Bit Absolute Encoder

The iESSH86-60-45-17BC-RC/EC is a 4.5 N·m Integrated closed loop Stepper Motor in an 86 mm frame, combining drive, motor, RS485/CAN/EtherCAT fieldbus, and a 17-bit absolute encoder. It operates from 60 VDC at 6.0 A, a voltage tier that keeps the power-bus cost below the 80 VDC models while retaining the mechanical stiffness of the larger frame. This unit is supplied as a complete axis for machine builders who need the 86 mm footprint without moving to a high-voltage bus.

One-Unit Drive and Motor

The drive mounts on the motor, so the axis connects to the machine with a DC supply and a fieldbus cable. There is no separate driver to install and no phase wiring between driver and motor. On machines with several axes, this cuts installation labor and keeps each axis independently replaceable.

Frame Size and Power Tier

The 86 mm frame gives a large mounting face for torque reaction, while the 60 VDC input reduces power-supply cost compared with 80 VDC variants. The 6.0 A rating maintains strong torque for the frame.

Encoder Precision and Behavior

The 17-bit absolute encoder gives high-resolution feedback and keeps position after power loss. The closed loop corrects step errors during motion and holds position at standstill, which helps maintain repeatability in handling and packaging cells.

Specifications

• Frame size: 86 mm
• Holding torque: 4.5 N·m
• Supply voltage: 60 VDC
• Rated current: 6.0 A
• Fieldbus: RS485 + CAN / EtherCAT
• Encoder: 17-bit absolute
• Control mode: closed loop
• Design: compact, low vibration

Applications

Built for industrial automation, packaging machinery, robotics, and CNC machine tools. It fits indexing mechanisms, small rotary tables, and transfer axes in the 4.5 N·m torque class, and the 60 VDC input suits lines where a lower power bus is preferred.

Commissioning Guidance

Use a regulated 60 VDC supply and set drive parameters to the 6.0 A current rating. Verify the fieldbus address and baud rate before enabling motion, and mount the motor to a metal surface for heat transfer. Contact Lyenwsin for commissioning documents and duty-cycle guidance.
