Product Description:

The SG-B1.023.042-10.010 belongs to the SG Synchronous Servo Motors series produced by Bosch Rexroth Indramat. It is a permanent-magnet AC servo motor intended for precise positioning and velocity control in industrial automation axes such as pick-and-place arms, packaging stations, and light machining heads. By linking directly to a drive controller, the motor converts commanded current into proportional torque so that motion profiles can be executed with tight repeatability. This operating behavior supports rapid starts, stops, and short positioning moves where steady response is important.

The electrical and dynamic figures show how the unit responds under load. Its nominal operating velocity is 4800 rpm, allowing rapid cycle completion on short-stroke mechanisms. At zero speed it can deliver 2.55 Nm of standstill torque, generated when the windings are supplied with the rated stator current. The torque constant of 0.54 Nm/A shows the proportional relationship between phase current and produced torque. During static hold the phases draw 4.8 A, a value that assists in sizing conductors and thermal protection. A low rotor inertia of 0.062 ×10⁻³ kg·m² enables fast acceleration and minimizes overshoot, which is useful for indexing tables that reverse direction frequently.

Mechanical features and sealing characteristics complement the electrical profile. The housing carries an IP65 rating, so dust ingress and low-pressure water jets do not reach internal components, and the frame is cooled by natural convection without fans. A resolver supplies closed-loop feedback, while SmCo magnets provide stable flux at elevated temperatures. The 4-hole front flange follows accuracy class R and has a diameter of 70 mm for alignment to precision gearheads. Overall length is 166 mm, and the motor weighs only 2.6 kg, which helps reduce load on linear carriages and supports use where installation space is limited. There is no mating connector fitted, so the cable connection can be arranged to suit the available routing.
