Product Description:

Bosch Rexroth Indramat manufactures the SF-A2.0020.060-10.050 for duties where compact dimensions and high rotational speed are required. The unit is part of the SF Servo Motors series and interfaces directly with Indramat drive controllers used in pick-and-place stations, feeders, and indexing tables. Its role is to translate controlled electrical power from the DC bus into repeatable mechanical motion so that position and velocity can be regulated. An absolute encoder mounted on the stator reports the exact shaft angle to the drive, enabling single-turn resolution without re-homing after power cycles.

Mechanical and electrical parameters describe the motor’s working range. The shaft reaches a rated speed of 6000 rpm, drawing power from a DC link held at 670 V. Torque generation is proportional to current with a constant of 0.74 Nm/A, giving predictable performance across the operating range. Mounting is performed against a 100 mm flange, and the smooth shaft is machined to Ø14 × 30 mm for coupling to gears or pulleys. When the shaft is blocked, the motor can withstand a locked-rotor torque of 2.0 Nm without damage. Dynamic response during acceleration is influenced by a rotor inertia of 3 × 10⁻⁴ kg·m², allowing quick changes in speed while minimizing overshoot. The overall body length measures 198 mm, which helps the unit fit into restricted cabinets.

Thermal management relies on natural convection, eliminating the need for forced air or liquid circuits and simplifying cabinet layout. The housing weighs 5.5 kg, providing sufficient mass to damp vibration while remaining light enough for gantry or delta-robot arms. Internal construction tolerates shocks up to 6 g, so the motor can be mounted on moving carriages without risk of demagnetization or bearing damage. The smooth shaft excludes a keyway to reduce wear, and the shock-rated winding set works with the integrated feedback system to maintain accuracy under rapid indexing.
