Product Description:

The SG-B1.034.036-00.029 is a brushless synchronous servo motor manufactured by Bosch Rexroth Indramat. It belongs to the SG Synchronous Servo Motors series. The motor converts regulated drive current into precise shaft rotation so that packaging stations, pick-and-place axes, and light assembly equipment can position loads accurately and repeatably within an automated cell. Its brushless design supports consistent servo response during repeated motion cycles.

An external machine frame connects to a circular flange that measures 70 mm across, and the motor uses the IM B5 mounting pattern for installation on a vertical plane. Straight flange sockets allow power and feedback cables to exit parallel to the axis, which helps reduce bending at the connectors and keeps cable routing compact around the machine face. At the rated electrical advance, the rotor can reach 3900 rpm, making it suitable for high-cycle production with short index times. When the shaft is energized but not turning, electromagnetic coupling produces a holding torque of 3.70 Nm, and a standstill phase current of 5.9 A is required to maintain that torque. The housing has an IP65 enclosure that helps keep airborne dust and directed water jets out of the motor.

The rotor’s mass moment of inertia is only 0.097 ×10^-3 kg·m², which supports rapid acceleration and deceleration in light moving axes. The electromagnetic design provides a torque constant of 0.66 Nm/A, linking commanded phase current to mechanical output in a predictable way. Total unit weight is 3.5 kg, which helps limit added load on gantries or robot arms. The motor also has a 204 mm overall length, an Ø11 × 23 mm keyed shaft, and a permissible axial load of 75 N, so it fits compact machine layouts while providing secure torque transfer to connected components.
