Product Description:

The SR-A2.0013.030-10.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat in the SR Synchronous Servo Motors series. Designed for industrial automation, it converts electrical energy from a pulse-width-modulated drive into controlled rotary motion for accurate position and speed regulation. This makes it suitable for pick-and-place arms, indexing tables, and other compact motion axes where repeatability and stable servo response are important. It is intended for closed-loop motion systems that rely on consistent acceleration, deceleration, and settling behavior.

During continuous operation, the motor runs from a shared DC bus of 670 V and reaches a rated speed of 3000 rpm. The electromagnetic design produces torque in proportion to current with a constant of 1.5 Nm/A, which gives the drive a predictable current-to-torque relationship. Mechanical mounting uses an IEC square flange with a face size of 100 mm, and the housing length is 186 mm. The solid steel shaft is 14 mm in diameter and 30 mm long, allowing torque transfer through keyed or clamping couplings. A molded housing seal and fully enclosed connectors support an enclosure rating of IP67, which helps protect the motor in dusty areas and washdown zones.

Dynamic response is influenced by a rotor inertia of 2×10⁻⁴ kg·m², which supports quick acceleration and controlled speed changes. The motor itself weighs 4.0 kg, helping limit added mass on moving assemblies such as gantries or transfer arms. Feedback to the drive is supplied by a resolver with an equivalent resolution of 8192 increments per revolution, allowing fine position feedback in closed-loop motion. The unit tolerates mechanical shock up to 6 g without losing alignment. It also withstands stall conditions with a locked-rotor current of 0.9 A that produces 1.3 Nm of holding torque.
