Product Description:
The SD-B5.250.020-41.000 is a brushless servo motor produced by Bosch Rexroth Indramat as part of the SD Magnet Motors series. Designed for mid-range duty cycles, it supplies closed-loop rotary motion for indexing tables, pick-and-place heads, and other axes that demand repeatable positioning in automated machinery. Electronic commutation eliminates brush maintenance and supports rapid reversals, allowing the unit to integrate with digital drives and fieldbus controllers in a compact envelope. Its operating profile suits applications that need controlled starts, stops, and direction changes without the wear associated with contact-based commutation.
A mounting flange of 116 mm offers a rigid interface for direct coupling to gearheads or machine frames. The rotor uses Ferrite magnets, providing stable residual flux without rare-earth materials. Under nominal load, the shaft reaches 2000 rpm, a speed that balances thermal rise with servo bandwidth. When held stationary, the motor can deliver 25 Nm of torque, allowing vertical loads to be supported during dwell periods. Power transmission passes through a shaft with dimensions of ø 19 × 40 mm, so standard clamping hubs or keyed couplings can be fitted without additional machining.
The unit relies on electronic commutation so motion controllers can apply complex velocity profiles without mechanical sparking or contact wear. Its winding and magnet circuit are matched for the stated operating range, which helps the motor respond smoothly to changing command inputs during cycle-to-cycle operation. This arrangement supports precise changes in speed and direction during repeated positioning cycles. The product information describes a standard motor configuration. Steady holding, quick reversals, and accurate stop points are supported during normal operation on cyclic axes.
