Product Description:

The SG-B0.007.070-03.000 synchronous servo motor is produced by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. It converts drive current into tightly controlled rotary motion for indexing tables, pick-and-place heads, and miniature conveyors used in industrial automation. An integrated permanent-magnet holding brake secures the shaft when power is removed, allowing vertical loads to remain stationary without external clamping devices. Its compact frame and low rotor inertia help support short cycle times while keeping machine footprints small.

During operation, the motor reaches a nominal speed of 6800 rpm, supporting rapid traverse movements. At standstill, it can deliver 0.95 Nm of electromagnetic torque, and this value scales linearly with current because the torque factor is 0.34 Nm/A. The drive supplies about 3.0 A to hold the load torque without overheating. The brake coil is energized by 24 V ±10 %, draws 11 W, and adds only 0.002 × 10⁻³ kg·m² to the reflected inertia, so responsive acceleration can be maintained. A Ø9 × 20 mm shaft fitted with a 3 × 3 × 14 mm feather key transfers motion, while the Ø24 mm pilot diameter and M2.5 × 8 threaded holes position the housing. Flange accuracy grade N maintains concentricity during assembly.

The brake provides a static holding torque of 0.9 Nm, preventing drift under gravitational or process loads. The overall assembly length, including the brake module, is 165 mm, and the motor weighs only 1.7 kg, simplifying installation on lightweight gantries. A square mounting interface measuring 55 mm on each side mates directly with precision gearheads or adapter plates. The shaft and pilot dimensions support accurate coupling alignment, while the threaded mounting holes provide secure attachment to compatible machine structures.
