Product Description:

The SG-B0.014.058-10.010 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. The unit serves as a rotary actuator in industrial automation, converting commanded current into precise shaft movement for tasks that demand repeatable positioning and stable velocity. Resolver feedback is integrated for real-time rotor angle reporting, enabling the drive controller to close position and torque loops with minimal latency and improved accuracy.

High-speed motion is supported by a nominal speed rating of 6200 rpm. Dynamic behavior is influenced by a rotor inertia of 0.041 × 10⁻³ kg·m², a low mass moment that permits rapid acceleration yet limits load mismatch. At zero speed, the motor generates 1.70 Nm of torque, and this torque is produced by a steady-state phase current of 4.0 A, providing a straightforward basis for sizing the associated amplifier. The mounting interface follows the IM B5 pattern, so the frame bolts directly to a driven machine wall or gearhead flange. The enclosure reaches an IP65 protection level, shielding the stator windings and resolver electronics from dust ingress and low-pressure water jets encountered in machining or packaging cells.

A circular flange diameter of 55 mm mates with pilot bores machined to accuracy grade R, keeping radial runout within tight limits for coupling alignment. Power is delivered through a smooth shaft that measures Ø9 × 20 mm, allowing clamp collars or shrink discs to transfer torque without key stress concentrations. The body has an overall length of 199 mm, and the assembly weighs 2.3 kg, reducing cantilever loads on lightweight gantry axes. Continuous torque can be estimated from phase current by a factor of 0.43 Nm/A, simplifying quick thermal checks while the embedded winding temperature detector signals the drive before overheating occurs.
