Product Description:

The SG-B0.004.076-10.010 is a permanent-magnet synchronous servo motor produced by Bosch Rexroth Indramat within the SG Synchronous Servo Motors series. In automation systems, it converts controlled electrical input into precise rotary motion for positioning axes, feeder drives, or lightweight robotics. The resolver feedback supports closed-loop regulation by downstream drives, and natural convection cooling allows the unit to operate without forced airflow. When paired with the designated SM 3.5/8-G(C)16 servo module, the motor forms a matched drive package for small mechanical loads.

During continuous operation, the rotor reaches a nominal mechanical speed of 7400 rpm, giving the application a high cycle rate without exceeding thermal limits. At zero speed, the electromagnetic design can generate 0.50 Nm of holding torque, which is enough to maintain position for light indexing tables. With a torque constant of 0.30 Nm/A, the controller can predict output torque directly from phase current, which simplifies current-mode control loops. To establish the magnetic field, the windings draw a standstill current of 1.7 A, and the complete electromechanical package is rated for 0.5 kVA of apparent power on the DC bus.

The motor housing follows the IM B5 flange-mount outline so it can bolt directly onto gearheads or machine frames without foot supports. In transient moves, the drive may accelerate the shaft up to 10000 rpm, providing motion reserve above the nominal setting. Dust-tight construction and water-jet sealing meet the IP65 category, allowing installation on the production floor next to process equipment. Greased-for-life bearings are sized for 20000 h of service, which aligns their replacement interval with general machine maintenance schedules and helps limit unplanned downtime.
