Product Description:

The AS1050-0000 is a stepper motor manufactured by Beckhoff and belongs to the AS Stepper Motors series. Within an automation cell, it serves as a positioning actuator that advances or retracts mechanical elements in fixed angular increments commanded by a pulse train. Because no feedback device is integrated, the motor is commonly paired with drive electronics that count steps to determine position, providing a simple means of motion control in packaging machines, laboratory instruments, and light material-handling stations.

Each revolution is divided into 200 full steps, corresponding to a fundamental step angle of 1.8°, which establishes the native positioning resolution. The motor produces a static holding torque of 1.2 Nm, so a load that attempts to turn the shaft must overcome this value before motion occurs. Electrical input is characterized by a phase-to-phase resistance of 0.28 Ω and an inductance of 0.86 mH; together they influence current rise time and microstepping smoothness. The windings are rated for a continuous phase current of 5.0 A, allowing the drive to deliver a mechanical output of 27.5 W without exceeding thermal limits. With no incremental encoder and no second shaft, the design concentrates mass near the rotor, keeping inertia at 0.36 kg cm² and supporting quick acceleration of modest loads.

On the mechanical side, the AS1050-0000 can accept an axial load of 15 N on the shaft without impairing its bearings, and backlash at standstill is limited to ±0.054°, supporting repeatable bidirectional moves. The housing carries an IP43 protection rating, permitting installation in control cabinets where dust is present but water spray is absent. Overall mass is 1.00 kg, which helps minimize structural loading on linear stages while still providing sufficient rotor momentum for stable low-speed operation.
