Product Description:

The SG-B0.007.070-00.000 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. Designed for precise position and velocity control in tightly integrated automation axes, it pairs with a brushless resolver for feedback and can reach a nominal operating speed of 6800 rpm. The model uses a shaft with a keyway and feather key to transmit torque without slippage, and it is intended to operate in ambient temperatures from 0 to 40 °C, making it suitable for general machine-tool and material-handling cells. Its compact format also supports installations where limited mounting space must be balanced with accurate servo response.

At a standstill, the motor can generate 0.95 Nm while drawing 3.0 A, which indicates its continuous holding capacity before the thermal rise reaches 100 K. The low rotor inertia of 0.022 × 10⁻³ kg·m² allows rapid acceleration, enabling the shaft to approach the maximum mechanical limit of 9000 rpm when driven by a compatible inverter. Electrical demand is moderate because the winding set is rated for 0.6 kVA, which helps keep required supply capacity low in compact control cabinets. With a body length of 148 mm, the unit fits into small machine frames, and a torque calculation factor of 0.34 Nm/A links commanded current to produced torque for predictable drive behavior.

The mechanical interface follows a 55 mm square flange that mates directly with standard planetary gearheads. An IP65 housing seals the stator against dust and water jets, allowing routine cleaning without additional covers and helping protect internal components during normal factory use. Static mass is 1.5 kg, which helps reduce reflected inertia on lightweight pick-and-place gantries, while the hardened shaft diameter of Ø9 × 20 mm can handle an axial thrust of 75 N during vertical positioning. These mounting and protection features make the motor suitable for compact axes that need sealed operation and low moving mass.
