Product Description:

The SD-B5.380.030-04.000 is a brushless servo motor manufactured by Bosch Rexroth Indramat as part of the SD Magnet Motors series. It converts command signals from a drive controller into controlled rotary motion for positioning tables, pick-and-place actuators, and other industrial axes that need precise torque and speed control. The motor’s mechanical footprint and integrated parking brake make it suitable for direct mounting on machinery where compact, closed-loop performance is required. In typical automation service, that layout supports accurate starts, stops, and speed changes across repetitive production cycles without adding a separate brake assembly at the machine frame.

The motor is built on a 116 mm mounting flange, a dimension that fixes the bolt circle and supports installation on matching machine faces. A keyed output shaft measuring Ø 19 × 40 mm transmits torque to couplings while keeping overhang loads within the rated limits. Under rated excitation, the rotor reaches 3000 rpm, supporting fast indexing and rapid speed changes in cyclic motion. When motion is commanded to stop, the windings can hold the load statically with 38 Nm of continuous standstill torque. Once de-energized, the mechanical brake supplies up to 36 Nm of holding torque to lock the shaft and help prevent axis drift during power loss or idle periods.

Magnetic excitation comes from Ferrite blocks rather than rare-earth material, yielding stable flux density over a broad temperature range. The basic equipment includes a spring-applied disk brake that releases only when power is present, which is useful on axes that must remain in position after shutdown. Its electronically commutated construction classifies the unit as a brushless servo motor, eliminating brush wear and reducing particulate buildup inside the motor assembly. Because no extra sealing, sensor, or paint options are indicated, the motor is supplied in a standard configuration for general-purpose automation tasks. This keeps the configuration focused on the base motor, shaft, flange, and brake arrangement used for standard industrial motion applications.
