Product Description:

The SG-B1.034.036-00.000 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat as part of the SG Synchronous Servo Motors series. Designed for closed-loop drive systems, the unit converts drive current into precisely controlled torque so that CNC axes, pick-and-place modules, or compact transfer stations can position loads with repeatable accuracy. Its metallic housing and sealed construction allow direct mounting on machine frames without auxiliary covers, keeping the footprint small in automated installations.

The servo has a nominal shaft speed of 3900 rpm and a static torque rating of 3.70 Nm, balancing fast indexing with stable torque at standstill. The windings draw 5.9 A at standstill, providing the magnetic flux needed for full torque while the resolver tracks rotor position for immediate response. The motor has an ingress protection rating of IP 65, preventing airborne dust and low-pressure water jets from reaching the interior. Heat is removed through thermal radiation and natural convection, eliminating the need for a fan. A square accuracy-N flange measuring 70 mm supports IM B5 face mounting, and the motor can also be installed vertically in the IM V1 or IM V3 orientation without additional brackets.

High-energy SmCo magnets deliver stable flux even at elevated temperatures, complementing the insulation system classified as Class F according to VDE 0530. The motor can operate continuously at ambient temperatures from 0 to 40 °C, while vibration grade N helps protect attached mechanical components. A shaft with a keyway and feather key measures 11 mm × 23 mm and transfers torque directly to couplings or gearboxes. The motor does not include a holding brake, so the drive or an external mechanism must retain the load when power is removed, while power and feedback connections use a mating connector suitable for 1.5 mm² conductors.
