3.0 N·m Integrated Closed-Loop Stepper Motor in a 57mm Frame (iHSS57-36-30-RC/EC)

Compact Axis Integration for Multi-Motor Machines

The iHSS57-36-30-RC/EC puts the drive inside a 57 mm motor body, which is attractive when a machine carries several axes and every driver enclosure removed from the cabinet simplifies the build. Integration also shortens the motor-to-drive cable, removing a common source of noise and connection faults.

Application scenarios

A 57 mm frame with fieldbus control suits machines dense with small axes. Textile machinery is a natural home, running the many small motor positions on knitting, winding and warping frames where the network coordinates tension between stations. Packaging machinery uses it on small indexing wheels and tube sealing, and CNC machine tools fit it on light auxiliary axes. Food processing runs it on gentle conveyor and divider mechanisms, while precision robotic mechanisms and automated handling use the closed loop for repeatable motion. Because several units can share one 36 VDC bus and a single network, machine builders reduce wiring and cabinet bulk across the whole line.

Closed-Loop Performance at 3.0 N·m

Holding torque of 3.0 N·m combined with 1000 P/R encoder feedback gives the axis closed-loop correction. The drive samples rotor position and adjusts current accordingly, reducing low-speed vibration and improving positional repeatability during frequent direction changes.

Choose Your Fieldbus

RS485, CAN and EtherCAT interfaces cover both legacy PLC systems and modern real-time networks. Protocol selection is done at configuration, so one motor model can be deployed across different machine lines.

Specification Summary

• Frame size: 57 mm

Selection and Operating Notes

Match the bus protocol to your controller before rollout; EtherCAT for tightly coordinated multi-axis, RS485 or CAN for simpler lines. Provision the 4.0 A rated current and regulate the 36 VDC rail. Since feedback is incremental, plan a startup reference move where absolute origin is required. The integrated drive means fewer spare modules to stock, and the compact 57 mm frame helps dense machine layouts.
