Product Description:

The SF-A3.0068.030-00.056 servo motor is produced by Bosch Rexroth Indramat for the SF Servo Motors series. It is a synchronous servo device engineered to supply closed-loop rotary motion in automated machinery such as gantry axes, indexing tables, and packaging lines. By translating controlled electrical input into mechanical torque, the unit supports repeatable speed and position during continuous manufacturing cycles. Its operating profile is suited to applications that require stable response during frequent starts, stops, and direction changes.

The motor operates from a DC link voltage of 670 V, enabling direct connection to high-power inverters without intermediate transformers. At its rated speed of 3000 rpm, it delivers continuous motion within thermal limits. During startup or blockage, the shaft can resist a locked-rotor torque of 6.8 Nm while drawing a locked-rotor current of 5.0 A. Electromagnetic conversion follows a torque constant of 1.36 Nm/A, so each ampere commanded by the drive produces predictable turning force. Dynamic response is also shaped by a rotor inertia of 11 ×10^-4 kg·m², which supports controlled acceleration and smooth speed changes under varying load conditions.

Motion control accuracy is further improved through electronic commutation coordinated with a permanently excited rotor, eliminating brush maintenance and permitting fast field transitions. An absolute value encoder supplies immediate position data after power-up, removing the need for homing sequences and supporting synchronized axis startup. Mechanical power is transmitted through a keyway and feather key machined to the DIN 6885 profile, allowing direct coupling to standard hubs and pulleys. This shaft arrangement supports secure torque transfer and consistent alignment during repeated industrial motion cycles.
