Product Description:

The SG-B1.034.036-04.000 is a synchronous servo motor supplied by Bosch Rexroth Indramat as a member of the SG Synchronous Servo Motors series. It converts controlled electrical current into precise rotary motion for automated equipment. The motor is intended for closed-loop axes that require accurate position and velocity control in industrial automation cells, packaging machinery, and pick-and-place actuators.

The motor reaches a nominal speed of 3900 rpm, allowing rapid cycle execution while maintaining motion accuracy. At standstill, it can deliver 3.70 Nm of continuous torque with a phase current of 5.9 A. Torque production scales linearly with current due to a torque factor of 0.66 Nm/A. For vertical axes or emergency stops, the integrated brake supplies 3.0 Nm of holding torque and consumes 10 W of coil power. The enclosure has an IP65 protection rating, sealing internal components against dust and water jets. Brake inertia is limited to 0.018 × 10⁻³ kg·m², and the brake assembly weighs 0.32 kg, reducing the additional load placed on the drive train.

The motor has a mass of 3.5 kg without the brake, making it suitable for lightweight gantries and robotic joints. Its housing measures 204 mm long without the brake section, allowing installation in narrow machine frames where axial space is limited. A square flange measuring 70 mm on each side provides the primary mounting interface and is machined to accuracy class N for repeatable alignment. Power is transmitted through a smooth shaft that measures 11 mm in diameter and has a free length of 23 mm. This shaft supports backlash-free clamping couplings for direct connection to gearboxes or other driven components. The brake is compatible with standard 24 V brake controllers, allowing the controller to release or engage the holding mechanism as required by the axis.
