Product Description:

The SF-A2.0013.030-14.050 is a brushless servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. This compact unit drives rotary axes in packaging lines, assembly cells, and material-handling stages by converting regulated stator current into mechanical torque for precise motion, repeatable positioning, and stable speed control. Because the motor is brushless, it avoids commutator wear parts and supports clean operation in repetitive-duty machinery. It has a 100 mm mounting flange that mates with gearheads or direct-coupled loads, and its 206 mm body length helps it fit shallow machine enclosures while still housing the internal feedback and holding brake used for closed-loop operation.

The motor reaches a rated shaft speed of 3000 rpm, giving a practical balance between speed range and resolver feedback performance for mid-power positioning tasks. The motor permits an axial thrust load of 70 N, which helps protect the bearings when belt tensioners or screw shafts apply end load during normal machine movement. It has a torque constant of 1.5 Nm/A, so the drive can relate phase current to produced torque with straightforward scaling during control. During startup or locked-rotor testing, the phase current can briefly rise to 0.9 A, and the motor develops a blocking torque of 1.3 Nm. These values support controlled verification of motor rotation without placing unnecessary thermal stress on the unit.

The spring-applied holding brake is energized at 24 V DC and clamps the shaft with 3.2 Nm of static torque, which helps prevent drift on idle Z-axes or indexing tables when motion is stopped. Dynamic response benefits from a rotor inertia of 2 × 10⁻⁴ kg·m², allowing quick acceleration while limiting stored kinetic energy during stopping. The motor has an overall mass of 4.3 kg, so it adds little structural load to compact axis assemblies and can be used where moving components must remain light. The brake contributes 0.35 kg of additional weight and 0.4 × 10⁻⁴ kg·m² of added inertia during deceleration, so the brake package has only a modest effect on the axis.
