Internal Product Review
The SD-B5 250.015-10.000 is a brushless servo motor with ferrite magnet construction. Basic equipment without keyway or brake supports straightforward integration, and 1500 rpm nominal speed fits steady servo duty well. Standstill torque rated at 25 Nm gives the motor strong low-speed holding performance for precise axis control.

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.
