Product Description:

The SD-B6.480.020-15.000 is a servo motor produced by Bosch Rexroth Indramat for the SD Magnet Motors series. It is intended for closed-loop industrial automation, where electronic commutation removes the need for brushes and supports precise torque delivery across repeated motion cycles. Within a multi-axis system, it converts drive current into rotary motion so that positioning tables, gantries, or material-handling fixtures can follow programmed profiles with stable speed and repeatable positioning. The brush-free design also avoids contact wear associated with brushed motors, which helps maintain consistent response during frequent starts, stops, and reversals.

The motor attaches to a machine frame through a 142 mm square flange, which centers the stator stack and helps keep axial runout within tolerance. It has a nominal speed of 2000 rpm, allowing the drive to reach a practical operating velocity under rated voltage while matching common gearing arrangements. A standstill torque of 48 Nm indicates how much load the motor can support while energized at zero speed. Mechanical power is transferred through a cylindrical shaft of Ø24×50 mm, providing enough engagement length for clamp couplings or keyed hubs. The unit is a Brushless servo motor, so commutation signals are generated electronically by the controller rather than by carbon contacts. The flange and shaft arrangement also supports accurate alignment with couplings, pulleys, or gear inputs when the motor is mounted to rigid machine structures.

Field characteristics are influenced by Ferrite magnets, which offer stable flux over a broad temperature range without relying on rare-earth materials. The motor is supplied in a standard configuration, so the insulation class, feedback arrangement, and mounting hardware follow the regular build for this model. A rigid flange interface keeps the stator concentric with the machine base, which helps reduce misalignment forces that can load the bearings. This is useful on a fast-moving servo axis where predictable magnetic behavior and straightforward mechanical integration are important. Ferrite magnet construction also suits general industrial duty where reliable operation and stable response are more important than maximizing torque density.
