Product Description:

The SG-B0.004.076-13.010 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. Designed for automated machinery, it converts electrical energy into controlled rotary motion that positions tooling, conveyors, or robotic joints with high precision. By integrating torque generation and feedback in a single assembly, the unit serves as a compact actuator for systems that demand accurate velocity and position profiles.

It delivers a continuous torque at standstill of 29.0 Nm while drawing a continuous standstill current of 46.4 A. With a torque constant of 0.62 Nm/A, every ampere supplied by the drive produces predictable torque output for closed-loop regulation. During normal operation, the rotor attains a nominal speed of 3000 rpm. Dynamic moves are accommodated by a peak current of 110.5 A, which the drive may supply for short intervals. The stator winding has a resistance of 0.25 Ω and an inductance of 3.1 mH, which influence thermal rise and current ripple. Digital servo feedback reports the rotor position with high resolution, enabling the controller to use these electrical characteristics for precise motion.

A shaft-mounted blocking brake rated at 40.0 Nm holds the axis when power is removed, preventing drift on vertical loads. Installation is centered by a 130 mm locating diameter, and the assembly weighs 36 kg, so the mounting hardware must support this static load. Torque is transferred through a keyway machined to DIN 6885. The rotor inertia of 120 × 10⁻⁴ kg·m² balances quick acceleration against smooth operation, while the theoretical maximum torque of 64.5 Nm indicates the highest permissible load demand. The motor reaches thermal equilibrium in 60 minutes. The power leads exit on side B, allowing cable runs to remain clear of the encoder wiring.
