Product Description:

The SG-B1.023.042-14.010 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SG Synchronous Servo Motors series. As a compact rotary actuator, it supplies controllable torque and velocity to indexing tables, packaging stations, and other motion axes in industrial automation. With an internal permanent-magnet rotor and resolver feedback, the motor supports rapid direction changes while maintaining the position accuracy needed in coordinated multi-axis systems. Its compact format also makes it suitable for machines where installation space is limited and low moving mass is important for responsive motion.

The unit reaches a nominal speed of 4800 rpm, allowing fast cycle times in pick-and-place or spindle duties. Its static torque rating is 2.55 Nm, which indicates the load it can hold at standstill. A standstill current of 4.8 A flows through the windings to produce that holding torque, and the torque factor is 0.54 Nm/A. Low rotor inertia, measured at 0.062 x 10^-3 kgm², helps reduce overshoot during high-gain position loops. The motor is therefore suited to lightweight loads that require quick acceleration and stable velocity control. Additional geometric details include flange accuracy class R and a housing length of 166 mm when no brake is fitted, which helps the motor fit into compact machinery layouts.

An optional Large Integrated A holding brake is energized by 24 V DC and engages within 20 ms, giving quick shaft locking during emergency stops or power loss; release occurs in 15 ms when voltage is restored. Mechanical connection is provided by a flange diameter of 70 mm and a shaft sized at Ø11 x 23 mm, allowing direct coupling to small gearheads or pulleys. When the brake is installed, the overall length increases to 188 mm and the assembly weight rises to 3.1 kg. These dimensions should be considered wherever adjacent components, guards, or couplings leave little extra clearance around the motor body.
