Product Description:

Bosch Rexroth Indramat manufactures the SF-A3.0068.030-10.050 servo motor within the SF Servo Motors series. The device converts commanded current into controlled shaft rotation for motion axes in industrial automation. Its architecture follows closed-loop servo practice and uses feedback from the built-in absolute encoder so the drive can regulate torque and velocity with repeatable accuracy. This arrangement supports repeatable motion during indexing, positioning, and speed changes under varying load conditions. It is suitable for indexing tables, pick-and-place gantries, and other equipment that requires quick acceleration, precise positioning, and frequent duty cycles.

It mounts on a B5 flange whose outside circle measures 116 mm, giving a rigid interface for gearboxes or direct-drive couplings. Rotor inertia, including the encoder, is 11 × 10⁻⁴ kg·m², a low value that helps the axis accelerate quickly while limiting overshoot. When the rotor is locked, the winding draws 5.0 A and develops a stall torque of 6.8 Nm. A torque constant of 1.36 Nm/A lets the drive relate commanded current to expected mechanical torque. The absolute encoder provides position data without a homing routine after power is restored, and the smooth shaft with a 19 mm diameter and 40 mm length supports backlash-free clamp couplings.

The housing mass of 9.0 kg helps absorb thermal transients while keeping installation manageable. An overall body length of 255 mm allows the motor to fit in compact machine frames without reducing bearing spacing. Nominal operating speed reaches 3000 rpm, allowing fast cycle times when the motor is paired with a matching drive. Resistance to mechanical shock is rated at 6 g, helping encoder alignment and bearing clearances remain stable during rapid indexing stops or tooling impacts. The shaft format is also compatible with clamp collars and shrink-fit hubs, which can support rigid and low-backlash power transmission.
