Product Description:

The AS1020-0000 is a hybrid stepper motor manufactured by Beckhoff as part of the AS Stepper Motors series. It is intended for open-loop positioning tasks in industrial automation, where each input pulse advances the shaft by a fixed angle. The motor provides repeatable indexing for pick-and-place heads, light conveyors, and labeling stations, making it a practical alternative to servo technology when moderate speed and torque are sufficient.

Electrical performance is anchored by a holding torque of 0.50 Nm, allowing fixtures to remain stationary when the windings are energized. Continuous phase demand is limited to 1.00 A, so the device pairs with low-current micro-stepping drives and helps limit heat generation. At the rated electrical input, the motor delivers 10.0 W of output, which is suitable for light automation axes. Positional granularity is fixed at 1.8°/200 full steps, and this native resolution can be divided further in micro-step mode for smoother motion. The copper windings have an inductance of 9.50 mH, which shapes current rise time and limits the highest practical step frequency, while the measured resistance of 4.80 Ω sets the voltage needed for full-scale torque production.

The housing is rated IP43, allowing operation in controlled indoor enclosures without exposure to heavy spray or dense dust. The laminated rotor has an inertia of 0.074 kg·cm², giving predictable acceleration during short-stroke moves. Angular error at standstill is limited to ±0.09°, and shaft end play remains within an axial window of 0.075 mm; radial play is 0.025 mm. A smooth shaft with one flat simplifies set-screw fastening, no second shaft is present, and the electrical interface uses an M12 cable bundle. The model is supplied without an incremental encoder, so position verification must be handled at the system level.
