Product Description:

The SF-A3.0093.030-04.056 servo motor is produced by Bosch Rexroth Indramat within the SF Servo Motors series. It serves as a rotary actuator in automated lines, allowing precise speed and position control for conveyors, pick-and-place arms, and other axes. An integrated absolute value encoder reports the shaft position directly to the drive, so the axis retains its reference after a shutdown and restarts without a homing sequence.

At a rated speed of 3000 min⁻¹, the motor delivers continuous motion suitable for medium-inertia loads. The flange diameter of 116 mm follows the DIN mounting pattern, simplifying interchange with other frame sizes. Electromagnetic behavior is characterized by a torque constant of 1.35 Nm/A, meaning each ampere of phase current produces proportional torque, while a locked-rotor torque of 8.1 Nm defines the maximum shaft load that can be held when the rotor is energized but stationary. For static safety, the integrated spring-applied brake supplies a holding torque of 10.0 Nm at 120 °C. Additional data include a locked-rotor current of 6.0 A, a brake rated current of 0.66 A, a brake inertia of 1.06 ×10⁻⁴ kg·m², and a brake mass of 0.6 kg, all of which guide drive sizing and deceleration profiles.

Environmental and mechanical resilience is provided by an enclosure rated to IP67, allowing installation in wash-down or dust-laden zones, and by a shock resistance of 6 g that absorbs brief mechanical impacts. The brake disengages at a supply of 24 VDC, drawing 0.66 A and adding its dedicated mass to the assembly. Including the encoder, the overall rotor inertia reaches 16 ×10⁻⁴ kg·m², a value that balances rapid acceleration with smooth velocity control. These figures help machine designers meet positioning accuracy targets while maintaining environmental sealing and vibration tolerance.
