Technical data

Built for compact precision

Closed-loop motion control in a 42 mm integrated package

The AI42RC is a 42 mm integrated closed-loop stepper motor that combines the motor and drive electronics in one compact package, reducing external component count and installation space.

Closed-loop precision

Closed-loop position monitoring supports controlled motion across dynamic operating conditions.

Compact integration

The 42 mm motor, drive and controller share one housing, simplifying cabinet architecture and reducing component count.

Wide logic-level support

Logic input levels from 3.3 V to 24 V support integration with a range of machine-control systems.

Integrated architecture

More motion capability. Less cabinet complexity.

The integrated design reduces the number of separate components, shortens field wiring and gives designers a clean platform for compact precision axes.

  • Motor, drive electronics and closed-loop control in one unit
  • Compact front interface for power and logic I/O
  • Four motor lengths for compact machine-axis design
