Product Description:

The SF-A3.0068.030-10.000 servo motor is built by Bosch Rexroth Indramat within the SF Servo Motors series. This permanent-magnet unit converts electrical energy into controlled mechanical rotation for positioning duties in automated assembly lines, conveyors, and pick-and-place modules. Its body length is 255 mm, allowing placement in compact machine frames, and the integrated feedback device supplies position data to the drive without needing a homing routine at power-up. It is suited for controlled rotary motion in automated cells where repeatable response is required during frequent starts and stops.

Its electrical and mechanical values support stable matching with a compatible drive. A rated speed of 3000 rpm sets the upper continuous rotational velocity, while the torque constant of 1.36 Nm/A relates armature current to produced torque. During startup or when a load is jammed, the stator can deliver a locked-rotor current of 5.0 A that develops 6.8 Nm of stall torque. Rotor inertia, measured with the encoder, is 11 × 10⁻⁴ kg·m², which affects acceleration response and drive tuning. Heat is removed by natural convection, so no external blower is required, and two NTC sensors report winding temperature to the controller. The motor uses a smooth 19 mm × 40 mm shaft and IM B5 face mounting for direct machine attachment.

A flange dimension of 116 mm fits standard DIN mounting patterns, and the encoder resolves position to ±20 arc-sec / 8 million counts per revolution. The Single-Turn Absolute STG format preserves angle information across power cycles, which helps the axis return to operation without a homing pass. The housing carries an IP67 (except output flange) rating, so the main body is protected against dust ingress and temporary immersion. Total mass is 9.0 kg, which supports use on moving axes without making the assembly overly heavy. This combination supports installation in machinery where available mounting space and exposure to washdown spray are both limited.
