Product Description:

The SD-B5.380.020-04.000 is a servo motor manufactured by Bosch Rexroth Indramat for the SD Magnet Motors series. Designed for industrial automation, it converts controlled electrical input into repeatable rotational motion suited to packaging equipment, gantry axes, and general-purpose positioning stages. Electronic commutation removes brush wear, while integrated feedback from the associated drive keeps velocity and position loops tight, making the unit appropriate for installations that demand consistent response under cyclic duty. This arrangement also helps the motor maintain smooth acceleration and repeatable stopping behavior during frequent indexing cycles.

The motor attaches to machinery through a flange that measures 116 mm, matching common gearbox housings and keeping the stator concentric with the driven load. Its torque at standstill is rated at 38 Nm; this continuous value indicates how much static load the motor can support without drifting when energized in closed loop. During motion commands, the rotor can reach a nominal speed of 2000 rpm, providing balanced speed for mid-range conveyor or indexing tasks. Magnetic excitation is supplied by Ferrite permanent magnets, giving a stable operating flux without rare-earth materials. When power is removed, an internal brake applies a holding torque of 36 Nm to secure suspended or inclined axes.

The basic equipment package includes a spring-applied, electrically released disk brake, eliminating the need for an external stopping device and supporting secure axis holding when power is off. Mechanical output is delivered through a ø 19x40 mm keyed shaft, allowing direct coupling to standard clamping hubs with minimal backlash. Because the construction follows a brushless servo motor scheme, maintenance intervals are extended and dynamic torque can be modulated rapidly by the drive electronics. The keyed shaft format also supports reliable torque transfer to couplings and pulleys used on compact machine axes.
