SG-B1.034.036-13.010

The SG-B1.034.036-13.010 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. The unit is designed to generate commanded torque and speed on compact axes in assembly stations, pick-and-place gantries, and packaging machines. As a servo element it converts drive current from a compatible inverter into precise rotary motion, allowing position loops to be closed quickly and repeatably while keeping motor heating and cabinet space at moderate levels.

Mechanical attachment is handled by a flange that measures 70 mm on its locating face; this square geometry matches standard planetary gearheads and ensures concentric seating against machine frames. The shaft emerging through the flange has a diameter of 11 mm, giving sufficient torsional strength for couplings without excessive mass. Under rated excitation the motor develops 3.70 Nm of static torque at standstill, which is the torque available for holding or low-speed indexing. To sustain that value the windings draw 5.9 A of continuous current from the drive controller. When motion is commanded, the electromagnetic design permits a base speed of 3900 rpm, so high throughput can be obtained without an external transmission stage.

The remaining performance factors define dynamic response and integration limits. A rotor inertia of 0.097×10⁻³ kg·m² keeps acceleration times short, letting servos settle after small position corrections with minimal overshoot. Axial engagement depth for couplers is governed by the 23 mm shaft length, a value chosen to accept standard keyed hubs while maintaining bearing preload. For each ampere beyond standstill the motor delivers incremental torque according to its constant of 0.66 Nm/A, allowing the drive to calculate current feedforward tables accurately. These figures, paired with the manufacturing consistency of Bosch Rexroth Indramat, help engineers size the axis without iterative prototypes.
