5.0 A closed loop Stepper Motor with 17-Bit Encoder

The iESS60-36-30-17BC-RC is a 5.0 A closed loop Stepper Motor rated at 3.0 N·m holding torque, running from 36 VDC and controlled over RS485+CAN. The 60 mm unit integrates the drive and a 17-bit absolute encoder into one housing, and it is supplied as a complete axis for machine tools and industrial automation stations. The 5.0 A rating gives the drive headroom to supply the full winding current during acceleration.

Current Rating and Torque

At 5.0 A the drive can supply the full winding current for the 3.0 N·m holding torque, including the peak current during acceleration. This headroom makes the unit suitable for axes with short, frequent moves where open-loop systems would risk step loss.

Serial Fieldbus

RS485+CAN gives a choice of bus for the machine controller. Motion setpoints, status words, and closed loop gains are all accessible over the fieldbus, reducing the need for manual adjustments and simplifying the wiring compared with pulse/direction stepper systems.

Specifications

• Frame size: 60 mm
• Holding torque: 3.0 N·m
• Supply voltage: 36 VDC
• Rated current: 5.0 A
• Fieldbus: RS485 + CAN
• Encoder: 17-bit absolute
• Control: closed loop

Installation and Heat

The integrated drive adds heat to the motor body, so the frame must shed it. Bolt the flange to a metal surface and keep the housing clear; derate continuous torque if the ambient temperature is high. In warm machine cells, position the axis away from other heat sources where possible.

Applications

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

Sizing Notes

For short-cycle motion, confirm the duty cycle allows the frame to shed heat between moves, and set the current limits in the drive to match the winding rating. The absolute encoder removes the need for a homing move after a stop, which keeps the machine ready to resume production immediately.
