Product Description:

The SD-B5.380.020-00.000 is an AC magnet motor produced by Bosch Rexroth Indramat in the SD Magnet Motors series. It serves as a rotary actuator for industrial automation systems, where drive controllers command the rotor to precise angles and velocities for indexing tables, transfer lines, or pick-and-place axes. Permanent magnets on the rotor enable electronic commutation, so the unit maintains torque without mechanical brushes and reduces maintenance demands in production cells. This design supports smooth positioning during repeated indexing and transfer movements.

At zero speed, the motor supplies 38 Nm of standstill torque, giving fixtures enough holding force before acceleration starts. When energized, it operates at a nominal speed of 2000 rpm, a useful reference when matching gearheads or belt drives to the motor. A square mounting face with a 116 mm flange aligns the stator housing on machine plates while supporting radial loads transmitted through the output shaft. The output shaft measures Ø 19 × 40 mm, allowing standard couplings to slide on without additional machining. Magnetic excitation is generated by Ferrite blocks embedded in the rotor, providing stable flux density over a broad temperature span.

Power transfer is delivered through a shaft that incorporates a keyway and a matching feather key, so torque is positively locked to the driven hub even under reversing loads. The motor is classified as a Brushless servo motor, meaning its phase currents are sequenced electronically rather than through commutator contacts, which supports quiet running at low speed. Because phase switching is handled electronically, low-speed operation remains smooth and brush wear is eliminated. This arrangement supports reversing motion and repeatable positioning in servo-driven machinery.
