2.0 N·m Closed-Loop Stepper Motor with Integrated Drive

The iESSH60-36-20-17BC-RC/EC combines a closed-loop stepper motor and its driver in a single 60 mm housing. Rated at 2.0 N·m holding torque and 5.0 A phase current on a 36 VDC bus, it targets axes where panel space is limited and running a separate drive is not practical.

Where the 2.0 N·m Rating Fits

Two newton-metres of holding torque suits medium-size positioning stages and light conveying axes. The integrated drive removes the motor-driver cable run, which also eliminates a common source of step-pulse noise in conventional stepper systems.

Bus Variants and Remote Tuning

Choose RS485+CAN or EtherCAT for this model. The closed-loop parameters, current settings, and motion data are reachable over the fieldbus, so parameter changes do not require physical access to the unit.

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

Position Hold and Stiffness

Closed-loop control corrects missed steps in real time rather than waiting for the next homing operation. The result is better stiffness during load changes and a more repeatable final position compared with an open-loop stepper of the same frame size.
