Product Description:

The SD-B5 250.015-10.000 is produced by Bosch Rexroth Indramat and belongs to the SD Magnet Motors series. It serves as a servo actuator in industrial automation, converting commanded electrical energy into rotational motion so that drive controllers can position tooling, conveyors, or assembly fixtures with repeatable accuracy. Within a closed-loop axis, the motor supplies controlled torque while an external sensor reports speed and angle to the controller, allowing tightly synchronized multi-axis processes across packaging, printing, and material-handling equipment. That operating role makes it suitable for axes that must start, stop, and reverse direction with predictable response under drive control.

With a flange size of 116 mm, the motor bolts directly to common IEC interfaces and supports rigid mounting without adapter plates. At a nominal speed of 1500 rpm, it reaches thermal steady state while maintaining linear velocity, which suits conveyor or spindle duties that must avoid overshoot. A standstill torque of 25 Nm allows the axis to hold load during indexing or dwell periods without external brakes. The rotor uses ferrite permanent magnets, providing consistent flux density over a wide temperature range and avoiding rare-earth sourcing constraints. Motion is transmitted through a shaft that measures ø 19 × 40 mm, giving sufficient diameter and engagement length for clamp or hub couplings while preserving a compact overall package. The shaft format supports direct connection to common machine-side elements without requiring an oversized motor body.

The unit is supplied as basic equipment, with a shaft without a keyway and without a brake at the rear housing. Because the shaft is plain, torque transfer depends on the selected coupling rather than a keyed connection, which can be useful where precise hub alignment is required. Classified as a brushless servo motor, it uses electronic commutation to remove brush wear during rapid acceleration cycles. This also helps minimize electrical noise while the motor is operating in closed-loop motion systems.
