Product Description:

The SG-B1.034.036-13.010 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. Designed as a compact rotary actuator, the unit links directly with Rexroth digital drive modules to translate controlled stator currents into precise shaft rotation. In automated machinery, it supports point-to-point moves, interpolated paths, and continuous speed regulation, giving machine builders a closed-loop source of mechanical power for pick-and-place gantries, feed rolls, or auxiliary packaging axes.

At a nominal speed of 3900 rpm, the motor reaches its rated back-EMF and cooling equilibrium, allowing the connected inverter to deliver full performance without an overspeed margin. The standstill torque of 3.70 Nm represents the static twisting force available when the shaft is locked and energized, so vertical loads can be held without a mechanical brake. To sustain that torque, the windings draw a standstill current of 5.9 A, and this value helps determine the required drive amplifier rating and conductor size. A torque constant of 0.66 Nm/A expresses the linear conversion from phase current to output torque, allowing control algorithms to calculate the required current during acceleration or precise positioning.

A flange size of 70 mm permits direct mounting to standard ISO servomotor interfaces, reducing the need for adapter plates. The rotor inertia is limited to 0.097×10^-3 kg·m², so the axis can accelerate rapidly while still offering stable control at low speed. Power is transmitted through a keyed shaft with an 11 mm diameter and a usable length of 23 mm, dimensions chosen to match compact couplings or planetary gear inputs. This shaft format supports compact drive-train layouts where quick response and accurate servo motion are required.
