Product Description:

The SG-B0.014.058-13.010 is a synchronous servo motor built by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. Designed as a compact rotary actuator for industrial automation, the unit pairs with matching Indramat drives to deliver closed-loop motion control in assembly, packaging, and material-handling axes. Its electromechanical construction converts commanded current into precise torque, allowing the machine controller to position loads accurately within milliseconds. It mates electrically with Indramat digital drives that manage current, speed, and position. That operating role suits compact machine sections where short travel distances, frequent indexing, and repeatable settling are required throughout the production cycle.

The motor has a nominal speed of 6200 rpm and a continuous standstill torque of 1.70 Nm. At zero speed, the windings draw 4.0 A, and each ampere yields 0.43 Nm/A, which supports predictable torque production. The servo module must source 0.75 kVA, which helps determine suitable supply capacity and cable selection. A brushless resolver delivers absolute position, and the paired SM 4.7/20-G(C)16 module closes the velocity and position loops. Its resolver supplies sine-cosine signals that the controller interpolates to high resolution, avoiding commutation ripple during slow moves. Standstill current remains stable because the laminated stator core minimizes eddy losses, keeping temperature rise predictable during static holding tasks. This combination helps the axis respond cleanly to speed changes while maintaining stable low-speed behavior during positioning and dwell periods. Motion is transmitted by a smooth 9 × 20 mm shaft suited to clamp or shrink couplings.

The housing meets IP65, blocking dust and low-pressure water jets common on factory floors. A 55 mm square flange with accuracy class R centers the frame on gearboxes without shims. An integral brake supplies 1.0 Nm of static torque to hold loads during power loss. Low rotor inertia of 0.041 x10^-3 kg·m² allows fast acceleration with limited overshoot, supporting tight start-stop cycles in pick-and-place or indexing equipment. The compact mounting face also helps the motor fit into tightly spaced mechanisms where alignment accuracy and shaft retention are important during repetitive cycling.
