42mm Integrated closed loop Stepper Motor with 0.7 N·m Torque (iHSS42-24-07-RC/EC)

Small machines often carry axes that need full control features but cannot spare the space for discrete drive hardware. The iHSS42-24-07-RC/EC is a 42mm Integrated closed loop Stepper Motor with the drive embedded in the frame, delivering 0.7 N·m from a 24 VDC bus with fieldbus connectivity.

A Miniature Axis With the Driver On Board

The drive embedded in the frame is a practical solution for small machines where a separate drive would occupy disproportionate panel area and add unnecessary cable length. Each axis is a self-contained module that connects to the DC supply and the RS485, CAN, or EtherCAT network, which keeps small machine builds tidy and serviceable.

Precise Motion on a 24 VDC Bus

Running from 24 VDC at 1.7 A, the motor delivers 0.7 N·m holding torque. Its 1000 P/R incremental encoder provides closed loop correction, holding position on small indexing tasks where open-loop step counting can drift under variable friction. The closed loop detects and corrects small deviations as they happen, improving consistency on short moves.

Fieldbus Interfaces on a Compact Scale

Despite its size, the unit supports RS485, CAN, and EtherCAT, so small axes can join the same network as larger machine modules instead of being controlled by separate point-to-point wiring. This keeps the overall control architecture uniform across the machine.

Key Specifications

• Frame size: 42 mm
• Holding torque: 0.7 N·m
• Rated current: 1.7 A
• Supply voltage: 24 VDC
• Feedback: 1000 P/R incremental encoder
• Communication: RS485, CAN, EtherCAT

Application Scope

This compact model fits factory automation mechanisms, packaging machinery, robotics, and CNC machine tools where low torque and a small physical footprint are the deciding factors. It is also a good match for laboratory and optical equipment where space is at a premium.

Selection Advice

Verify that the machine supply can deliver 24 VDC at 1.7 A and that the mechanical envelope of the 42 mm flange matches the mounting space. Lyenwsin provides the dimensional drawing and fieldbus setup documentation so the axis can be integrated without surprises.
