Product Description:

The SF-A2.0041.060-10.057 is a compact brushless servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. The unit is intended for closed-loop drive systems where high acceleration and repeatable positioning are required, such as pick-and-place modules, packaging machines, and feeder axes. By pairing with a suitable drive controller, the motor supplies programmable speed and torque so that mechanical subassemblies follow electronic motion profiles rather than fixed cam plates or pneumatic stops. This supports precise starts, stops, and reversals during repetitive production cycles. The brushless design also reduces wear associated with commutator-based motors.

The nominal operating point is 6000 rpm, meaning the shaft can rotate at six thousand revolutions per minute under continuous load without overspeeding the magnetic circuit. At that speed, every ampere delivered by the drive produces 0.73 Nm/A of electromechanical torque, which simplifies current-loop tuning. During startup, the drive may supply 5.6 Arms of locked-rotor current to overcome static friction and accelerate the load. The resulting stall torque reaches 4.0 Nm, giving the axis enough breakaway force for indexing or tensioning duties. A total housing length of 233 mm helps the motor fit in shallow machine spaces or on moving carriages.

The rotor inertia is 6 × 10⁻⁴ kg·m², which supports rapid speed changes with limited drive effort. Overall motor mass is 7.1 kg, so the assembly places only moderate load on linear stages or cantilevered brackets. The motor uses a keyed shaft with dimensions of Ø14 × 30 mm, providing a secure mechanical interface for pulleys or couplings while maintaining torsional stiffness. This arrangement helps the motor transmit torque without relying on a friction-only shaft connection.
