Product Description:
The AS2042-1H00 is a hybrid stepper motor manufactured by Beckhoff and grouped under the AS Stepper Motors series. As an incremental positioning device, it advances the shaft by fixed electrical steps, allowing straightforward open-loop motion control in packaging lines, pick-and-place gantries, and small conveyor modules found throughout industrial automation. It connects to Beckhoff drives that translate pulse trains into angular displacement without motor feedback.
Mechanically, the motor mounts to standard NEMA 34 frames with a flange dimension of 86 mm, and the shaft moves in discrete increments of 1.8° per full step. Its static holding capability reaches 6.4 Nm, while the nominal phase current of 5.6 A determines drive sizing. The aluminum rotor carries an inertia of 3.00 kg cm², balancing acceleration response and load matching. The electrical characteristics include a winding resistance of 0.41 Ω, an inductance of 3.4 mH, and a generated back EMF of 658 mV per radian per second. There is no feedback system, so position relies entirely on the commanded step count. The housing meets IP54, protecting against limited dust ingress and splashed water.
Radial bearings tolerate 176 N and axial thrust up to 60 N, making the unit suitable for pulley, leadscrew, or belt drives. During rapid indexing, it can deliver a breakdown torque of 4.2 Nm before losing synchronism. The copper windings may operate until 120 °C, allowing moderate thermal headroom when mounted in control cabinets with limited airflow. The keyed shaft follows a feather key profile for positive torque transmission, and the overall mass without an encoder is 3.0 kg, which eases installation on compact gantries. Open-loop operation makes stable load matching important because missed steps cannot be corrected by onboard position feedback.
