Product Description:

The SR-A5.0250.030-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. Designed for closed-loop motion control, it converts drive current into precise rotary output that positions machine axes, indexing tables, and material-handling fixtures. By combining permanent-magnet excitation with electronic commutation, the motor provides rapid torque response that improves cycle times in automated assembly and packaging equipment. The unit suits compact motion axes that must maintain position accuracy during continuous operation, including equipment exposed to vibration, splash, and frequent start-stop cycles.

At standstill, the motor produces 25 Nm of torque, letting machinery hold a load without motion. The torque constant is 1.44 Nm/A, so the controller needs modest current for commanded force. Static phase current reaches 16.1 A, a value that the windings can sustain continuously. A reflected inertia of 83 ×10⁻⁴ kg·m² supports rapid acceleration with limited overshoot. Operating speed peaks at 3000 rpm, aligning with common transmission inputs. The 32 mm shaft with a 58 mm key accommodates rigid couplings, and the housing length of 300 mm simplifies placement inside tight equipment layouts.

A sealed IP67 enclosure protects the motor from dust ingress and washdown spray. Motion feedback is supplied by a resolver offering 8192 incr/rev resolution, while its accuracy stays within ±10 arcmin for consistent positional data. Two NTC temperature sensors in the stator enable the drive to reduce load before excessive heating. The assembly weighs 24 kg, which limits additional mass on moving axes yet provides structural rigidity for the 32 mm shaft. This is useful on transfer units and rotary tables where added inertia can affect response.
