Product Description:

Beckhoff manufactures the AS2041-1H10 as part of the AS Stepper Motors series for incremental positioning tasks in industrial automation. The unit is a two-phase stepper motor that converts discrete control pulses into accurate shaft rotation. It is suitable for pick-and-place axes, small gantries, or indexing tables that require repeatable movement without closed-loop feedback.

The motor withstands an axial load of 60 N, allowing moderate thrust along the shaft while maintaining bearing life. A holding torque of 3.3 Nm keeps the load stationary when the windings are energized but motionless, while a breakdown torque of 2.2 Nm marks the limit before step loss occurs during acceleration. Integrated single-turn feedback provides 1,024 increments per revolution, and the encoder electronics are powered from a 24 VDC supply available in most control cabinets. The maximum winding temperature is 120 °C, and the stator coils have a winding inductance of 2.0 mH together with a winding resistance of 0.30 Ω, which influence current rise time and drive sizing. With a protection class of IP54, the housing resists dust ingress and water splashes, making it suitable for general factory environments.

The rotor inertia of 1.48 kg·cm² balances response speed against torque ripple, and the motor generates 340 mV/rad/s of back-EMF, which is relevant for drive voltage calculations. A radial load capacity of 200 N supports belt tension or pinion forces applied perpendicular to the shaft, and this is aided by a hardened steel shaft that measures 14 mm in diameter. Each full step advances the shaft by 1.8°, so 200 command pulses complete one mechanical revolution. Rated phase current is 5.6 A, and the assembled unit with encoder weighs 2.0 kg, permitting compact mounting on lightweight machine frames.
