Product Description:

The SD-B5.250.015-10.000 is a brushless servo motor manufactured by Bosch Rexroth Indramat as part of the SD Magnet Motors series. In automated machinery, it delivers regulated torque to positioning tables, feed rollers, and other motion axes while receiving current from a compatible servo amplifier. By combining permanent magnets with electronic commutation, the unit supplies consistent rotary motion without the maintenance needs of brushed designs. That operating principle makes it suitable for continuous industrial duty where repeatable starts, stops, and speed changes are required.

The mechanical interface follows a 116 mm square flange, allowing direct mounting to gearboxes or machine frames that conform to the same IEC size. Inside the stator, the excitation field is supplied by Ferrite magnets, a material that supports stable magnetic flux over typical industrial temperature ranges. Rated speed for the model is 1500 rpm, so the drive controller can command smooth motion profiles up to that velocity without exceeding the winding frequency limits. Delivered in basic equipment form without a brake, the shaft is free to coast when power is removed, so external holding devices must secure vertical loads. Within the SD Magnet Motors series, this motor is intended for servo applications that need controlled acceleration and repeatable axis response during normal machine operation.

Static capability reaches 25 Nm at standstill, providing sufficient holding torque for indexing operations before motion begins. Power is transmitted through a shaft sized 19 × 40 mm, and the smooth surface is supplied without keyway, so clamp couplings or shrink-fit hubs are recommended for torque transfer. The motor is supplied in a standard configuration, so its dimensional and electrical characteristics follow the regular product layout. This shaft arrangement helps maintain a compact interface for direct coupling to driven machine elements.
