Product Description:

The SG-B2.027.049-13.010 is a synchronous servo motor produced by Bosch Rexroth Indramat in the SG Synchronous Servo Motors series. The motor serves as a compact rotary actuator that works with an electronic drive to deliver tightly controlled position, velocity, and torque on automated axes. By converting three-phase drive power into rapid and repeatable motion, it allows conveyors, feeders, and small tooling spindles to follow precise motion profiles with high cycle accuracy. In compact automation cells, this format helps place controlled motion where installation space is limited.

Its electrical and mechanical values show how quickly a machine axis can be driven. A nominal speed of 5500 rpm gives the shaft headroom for overspeed commands during acceleration, while the standstill current of 6.8 A sets the continuous thermal limit when the rotor is locked. At that operating point, the motor can generate 2.6 Nm of stall torque, and each ampere contributes torque according to a 0.41 Nm/A torque constant. Dynamic response stems from a rotor inertia of only 0.000155 kg·m², so the servo reaches target speed with minimal lag. Axial mounting loads up to 150 N are permitted on the Ø19 × 40 mm keyed shaft. The mechanical interface uses a 100 mm square flange built to accuracy grade R, which supports direct attachment to gearboxes or frames without shims. This layout works well in compact motion assemblies where low rotating mass and stable shaft support are important.

The integrated holding brake secures vertical or oscillating loads when power is removed. It clamps the shaft with 6.0 Nm of static torque and is energized by a 24 V DC control line. Response times support quick tool clamping because the brake engages in 35 ms and releases in 25 ms, which helps reduce idle time between motion commands. Because the brake is built into the housing, the overall length measures 168 mm, and the complete assembly weighs only 4.1 kg, which helps keep moving mass low on gantry and delta robot axes. That combination suits applications that must hold position at rest and resume motion without long delays.
