Product Description:

The SG-B1.023.042-00.000 is a synchronous servo motor developed by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. In motion-control systems, the unit couples directly to a planetary gearbox or timing pulley and delivers controlled shaft rotation that matches command profiles from a compatible servo drive. Its role is to move machine elements quickly and accurately in repetitive industrial tasks. This operating profile suits packaging equipment, indexing assemblies, and other automated axes that depend on repeatable starts, stops, and position changes throughout the work cycle.

Its mounting interface follows a 70 mm square flange whose face runout complies with flange accuracy class N, supporting installation on standardized frames. A splined shaft is not used; instead, the mechanical output is provided through a cylindrical Ø11 × 23 mm shaft that accepts keyed couplings. During continuous stall, the motor can hold 2.55 Nm while drawing 4.8 A, so it can maintain torque without external cooling. When speed regulation is required, the motor can operate at up to 4800 rpm, a range suited to compact feeders and indexing tables. Housing gaskets and a radial shaft seal give the assembly an IP65 protection rating, allowing installation in areas exposed to dust and directed water jets.

The permissible axial force on the output end is 75 N, which helps limit bearing stress when belt tension or vertical loads act along the shaft. The motor has an overall body length of 166 mm, which helps determine the space needed for the drive train and surrounding machine components. Fast accelerations are assisted by a rotor inertia of 0.062 × 10⁻³ kg·m², which helps reduce drive torque overshoot during rapid speed changes. For every ampere added above the standstill value, the electromagnetic circuit produces 0.54 Nm/A, giving predictable torque scaling during transient moves so commanded current corresponds closely to mechanical output.
