Product Description:
The SF-A2.0013.030-04.000 is a brushless servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. As a compact rotary actuator, it converts drive current into precise torque and speed for positioning tasks in packaging lines, pick-and-place modules, and general motion axes in industrial automation. The unit integrates an electromagnetic brake and single-turn feedback, allowing coordinated stopping and position verification when power is removed. This combination supports controlled restarting after a stop and helps the drive maintain accurate axis behavior during repeated motion cycles. The motor is also suited to installations where limited mounting space must be balanced with dependable servo response.
It reaches a rated speed of 3000 rpm, and each ampere supplied to the windings produces 1.5 Nm/A because of its torque constant. Under steady operation, the brake can resist loads up to 3.2 Nm, so the shaft remains locked after a commanded stop. Position information is provided by a single-turn STG encoder with 8 million increments per revolution resolution, which supports tight position loops without external gearing. The holding mechanism is energized at 24 V DC, matching common control-panel supplies. Combined motor and feedback inertia is 2 × 10⁻⁴ kg·m², which supports quick acceleration and deceleration, while the Ø14 × 30 mm shaft is prepared with a keyway for direct coupling.
During start-up, the motor withstands 1.3 Nm of locked-rotor torque while drawing 0.9 A, so the drive can be set to appropriate current limits. The permanent brake circuit draws 0.56 A when engaged, and its added mass of 0.35 kg brings the total unit weight to 4.3 kg. With the brake installed, the overall length extends to 206 mm, and rotational inertia contributed by the brake is 0.4 × 10⁻⁴ kg·m². An A5 × 5 × 25 feather key seat simplifies hub alignment and helps transmit torque without slip at the shaft connection. Brake current and added inertia should be considered along with the driven load when matching the motor to the axis.
