Product Description:
The SF-A4.0125.030-10.011 servo motor is produced by Bosch Rexroth Indramat within the SF Servo Motors series. It is intended for closed-loop industrial axes that demand accurate rotary positioning and moderate continuous speed. By integrating an internal single-turn encoder and a sealed mechanical design, the motor supplies feedback and drive torque directly to packaging, assembly, and handling equipment without external gearing. Its electromagnetic construction supports medium-inertia loads so that motion commands can be executed with minimal overshoot and repeatable cycle times.
The motor has a torque constant of 1.37 Nm/A, which links drive current to generated torque for controller scaling. When the rotor is blocked, the winding can accept 10.6 A, resulting in a stall torque of 14.5 Nm. At the rated operating point, the shaft reaches 3000 rpm, allowing mid-range surface speeds without excessive centrifugal load. Position feedback supports this operating range through an encoder accuracy of ±20 arcsec, enabling interpolated positioning that stays within tight angular tolerances. The rotor inertia of 30 × 10⁻⁴ kg·m² moderates acceleration, balancing responsiveness with stable control for start-stop duty cycles.
Additional characteristics describe the motor's feedback resolution, shaft loading, sealing, and physical size. The single-turn sensor supplies 8 million increments per revolution, providing fine resolution for micro-stepping and dither suppression. A permissible axial thrust of 154 N protects the bearings when belt or pinion forces act along the shaft. The housing meets IP67, so dust and water exposure do not interfere with internal components during washdown operation. A mass of 16 kg together with the 277 mm overall length simplifies mounting on vertical plates, while the Ø24 × 50 mm smooth shaft aligns with standard coupling hubs. The motor emits 58 dB(A) under nominal load, limiting acoustic impact in work areas.
