Product Description:
The SG-B0.002.091-10.010 synchronous servo motor is built by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. It converts drive commands into controlled rotary motion for indexing tables, gantry axes, and packaging equipment. The unit is supplied without a blocking brake, so any load-holding duty must be managed by external mechanics or by maintaining drive torque when power is removed. This arrangement suits axes that already use a gearbox brake, counterbalance, or other external holding method.
At rated operation the shaft turns at 3000 rpm and delivers 29.0 Nm of standstill torque when heat is removed through surface cooling. Reaching that torque requires a phase current of 46.4 A, and the torque constant of 0.62 Nm/A shows how motor output rises in proportion to commanded current. For short acceleration bursts, the drive may supply up to 110.5 A before protection limits engage. A winding resistance of 0.25 Ω contributes to copper losses, while a 3.1 mH inductance influences current rise and helps the controller reduce ripple. These values help the motor respond smoothly during speed changes while keeping thermal loading within a practical range for repeated motion cycles.
The flange centers on a diameter of 130 mm, and the housing sealing meets IP65 for dust-tight and water-jet environments. The assembly weighs 36 kg, which should be considered when selecting mounts and handling equipment during installation. Rotor inertia is 0.0120 kg·m², providing predictable speed changes under medium loads, and position is reported to the drive through Digital Servo Feedback. The electromagnetic design can produce up to 64.5 Nm for short periods, and the casing needs 60 min to reach thermal equilibrium from a cold start. This combination supports accurate interpolation and stable servo response in multi-axis applications.
