Product Description:

The AS2023-0J10 is a two-phase stepper motor produced by Beckhoff within the AS Stepper Motors series and intended for precise position and speed control in automated machinery. Integrated with a single-turn incremental encoder, the unit feeds verified shaft position data back to Beckhoff drive controllers, enabling open-loop moves to be verified and corrected in real time. By delivering discrete step advances and high holding capability, the motor is suited for indexing tables, small pick-and-place axes, and metering pumps where repeatable motion is essential.

The electromagnetic section generates a static holding torque of 2.30 Nm, allowing the shaft to resist external loads without a brake. The nominal phase current is rated at 6.4 A, so the drive must support that continuous winding demand. Each full step advances the rotor by 1.8°, and the coupled encoder provides 1024 increments per revolution to refine microstepping accuracy. The coil resistance is 0.32 Ω, limiting I²R losses, while the 0.97 mH inductance moderates current ripple at typical switching frequencies. The encoder electronics draw 24 V DC and report position even when the motor phases are disabled. The generated back EMF constant is 185 mV/(rad/s), a value used by the controller for sensorless damping functions. With the feedback block installed, the assembly weighs 1.5 kg and has an overall length of 132.80 mm, permitting straightforward installation in cabinets that are 200 mm deep.

Peak dynamic output is characterized by a breakdown torque of 1.90 Nm, which is available during acceleration before the onset of a stall. The rotor inertia of 0.490 kg·cm² balances quick response with speed stability, while permitted shaft forces reach 15 N axially and 43 N radially. The winding system tolerates a maximum temperature of 120 °C. The frame has an IP54 protection rating, which guards the motor against limited dust entry and splashing water during operation.
