Product Description:

The SF-A3.0068.060-00.050 is an AC servo motor produced by Bosch Rexroth Indramat in the SF Servo Motors series. It is intended for positioning axes, indexing tables, and pick-and-place stations that require accurate speed control and repeatable torque response during frequent starts, stops, and direction changes. Integrated feedback helps the connected drive monitor rotor movement closely so commanded motion can be translated into stable and precise mechanical output. This makes the motor suitable for automated equipment where short cycle times and consistent positioning are important.

The motor mounts to machinery through a square flange that measures 116 mm, providing a fixed reference surface for alignment on machine frames or gearbox faces. During startup or stall conditions, the stator windings can draw a locked-rotor current of 8.5 A, which should be considered when selecting the drive and associated wiring. In that same locked-rotor state, the motor can produce a holding torque of 6.6 Nm to resist load before motion begins. The torque constant is 0.77 Nm/A, so phase current is converted into predictable torque output across normal operation. The rotor can reach a rated speed of 6000 rpm, supporting fast cycle rates in high-throughput machinery.

The motor has an overall mass of 9.0 kg, which provides solid thermal capacity without adding unnecessary load to moving assemblies. Its housing length, measured without an optional brake, is 255 mm, which helps the unit fit compact machine spaces while still accommodating the active motor section. Power is transmitted through a precision-ground shaft with a diameter of 19 mm, giving a common mechanical interface for couplings and related drive components. The shaft has an engaged length of 40 mm, providing usable contact area for secure torque transfer and stable connection to the driven mechanism.
