Product Description:

The SD-B3.068.030-05.000 is an AC servo motor produced by Bosch Rexroth Indramat and positioned within the SD Magnet Motors series. This unit belongs to the family of permanent-magnet synchronous motors that rely on electronic commutation rather than brushes, enabling fast response and low maintenance. In industrial automation, the motor forms the electromechanical link between a drive controller and a mechanical load, delivering accurate angular displacement and repeatable speed control for indexing tables, packaging mechanisms, and other motion axes that demand precise closed-loop positioning. Its operating principle supports smooth torque production and controlled acceleration where repeatable motion is required throughout frequent start-and-stop cycles.

The flange diameter measures 116 mm, so the housing fits standard machine plates without extra adapter rings. Rotor excitation is provided by Ferrite magnets, whose stable temperature behavior supports a predictable torque profile in general-purpose machinery. Under rated conditions the rotor turns at 3000 rpm, a speed commonly supported by mainstream drive inverters and suited for moderate inertia loads. The motor is built in a standard configuration, so its mechanical and electrical layout matches common drive connections and accessory parts used with this motor type.

As a brushless servo motor, the model uses stator windings controlled by Hall-free feedback to modulate torque, and it transmits motion through a shaft specified at Ø 19 × 40 mm, allowing direct coupling to gearheads or belt pulleys. The electromagnetic system can hold a load at standstill with 6.8 Nm of torque, a value sufficient for medium-duty axes such as small gantry arms. Matching feedback encoders, standardized cable sets, and thermal sensors support current, speed, and temperature control during normal drive operation.
