57mm Integrated closed loop Stepper Motor with 2.0 N·m Torque (iHSS57-36-20-RC/EC)

For robotic arms and automated stations, an axis that arrives as a single module saves layout time and panel space. The iHSS57-36-20-RC/EC is a 57mm Integrated closed loop Stepper Motor with the drive stage built into the motor body, combining 2.0 N·m of holding torque with encoder-based feedback and fieldbus control.

Drive Integrated Into a 57 mm Frame

With the drive stage built into the motor body, the iHSS57-36-20-RC/EC saves panel space and reduces interconnecting cables. For robotic arms and automated stations, this integration keeps the axis package short and the machine layout clean. Each axis connects only to the DC supply and the network, which shortens assembly and makes each unit independently serviceable.

2.0 N·m With Encoder-Based Correction

The unit holds 2.0 N·m and uses a 1000 P/R incremental encoder to close the loop. Real-time position feedback dampens resonance and reduces the risk of step loss, which matters on small axes moving through frequent starts and stops. The drive continuously compares commanded and actual rotor position, keeping the axis stable under varying load.

Network Options for Different Control Stacks

RS485, CAN, and EtherCAT are all supported. This flexibility allows the motor to drop into a simple point-to-point application or a fully synchronized EtherCAT line without hardware changes. The same unit can be stocked for multiple machine families, simplifying spare parts management.
