3.0 N·m Integrated Stepper Motor 57mm with closed loop Control (iHSS57-36-30-RC/EC)

Multi-motor machines benefit when each axis arrives as a complete, prewired module. The iHSS57-36-30-RC/EC is a 3.0 N·m Integrated Stepper Motor 57mm with the drive built into the motor body, so machine builders remove an external driver from the cabinet for every axis they install.

Compact Axis Integration for Multi-Motor Machines

Putting the drive inside a 57 mm motor body 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. The result is a cleaner machine layout and easier service access at each axis.

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. This is the practical benefit of choosing a closed loop integrated stepper over an open-loop design at the same torque.

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.

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 without hardware changes.
