Product Description:

The SD-B5.380.012-04.000 is a brushless servo motor produced by Bosch Rexroth Indramat and assigned to the SD Magnet Motors series. The unit converts electrical drive commands into controlled rotary motion for positioning tables, packaging axes, and other automated stations. Its brushless construction reduces maintenance and allows precise velocity control through matched servo drives in closed-loop systems. It is intended for machine axes that require accurate response during repeated positioning cycles.

At the mechanical interface, the motor provides a flange measuring 116 mm, a size that matches standard IEC mounting patterns so it can be fixed directly to gearboxes or frames without adapter plates. Rotor excitation is created with Ferrite magnets, giving consistent magnetic flux across the speed range. The rated operating velocity is 1200 rpm, which is the nominal speed for normal operation. When power is applied but rotation is blocked, the stator can develop 38 Nm of torque at standstill, allowing the axis to resist static load before motion begins. Coupling hardware must accommodate a shaft measuring Ø 19 × 40 mm, so the mating hub must match that diameter and length.

Dynamic holding requirements are addressed by the motor’s disk brake; the assembly supplies a residual brake-generated moment of 36 Nm, keeping vertical or suspended loads secure when the drive is de-energized. This function is supplied as basic equipment with a disk brake, so no external clamping module is required. The unit follows the standard electrical insulation, feedback, and sealing profile used across the series. As a brushless servo motor, it uses electronic commutation, so there is no brush wear during normal operation. This is useful on axes that must remain secured after drive power is removed.
