Product Description:

The Bosch Rexroth Indramat SF-A2.0041.030-00.000 is an AC servo motor in the SF Servo Motors series that provides rotary actuation for positioning axes in industrial automation. It converts controlled electrical energy from a matched drive into precise mechanical motion, enabling closed-loop speed and position control on packaging, material-handling, and assembly equipment. Its servo design supports repeatable movement in applications that require frequent acceleration, deceleration, and accurate stopping.

At the electrical interface, the motor is designed for a DC link of 670 V, which permits direct connection to high-power servo inverters without an intermediate step-up stage. A torque constant of 1.43 Nm/A gives the relationship between stator current and developed torque, helping the drive regulate output predictably. When the shaft is prevented from turning, the unit can sustain a locked-rotor torque of 4.0 Nm while drawing 2.8 A. Dynamic behavior is influenced by a rotor-plus-encoder inertia of 6 × 10⁻⁴ kg·m², which supports quick acceleration with limited drive effort. Mechanical integration uses a 100 mm square flange, and the smooth shaft, measured at 14 mm by 30 mm, mates with standard couplings. The housing length of 233 mm and a mass of 7.1 kg support compact mounting in dense multi-axis assemblies. A single-turn absolute STG encoder supplies position feedback, and two NTC thermistors embedded in the windings provide temperature monitoring for thermal shutdown.

The motor permits an admissible axial thrust of 70 N, allowing moderate belt or gear preload without excessive bearing wear. It meets IP67 sealing on every side except the output face, enabling washdown installation when the shaft end is shielded. During continuous duty, the rotor can reach 3000 rpm, furnishing the balance of torque density and speed required by conveyor, indexing, and pick-and-place axes that rely on rapid and accurate movement.
