Product Description:

The SD-B5.380.012-01.000 belongs to the SD Magnet Motors series produced by Bosch Rexroth Indramat. It is a compact brushless servo motor intended for closed-loop positioning and speed control in automated machinery where permanent-magnet torque generation is preferred over brushed designs. Within an axis drive, the unit converts commanded current into mechanical rotation while maintaining the feedback accuracy needed for packaging lines, pick-and-place systems, and light machining stations. Because it is brushless, there are no commutator brushes to wear during normal servo operation, which helps maintain consistent motion quality over repeated cycles.

The motor mounts to a machine frame through a flange that measures 116 mm, providing a standardized interface for direct-drive couplings or geared connections. Its rotor uses Ferrite permanent magnets, which provide stable magnetic performance across normal industrial temperature changes. The motor has a nominal speed of 1200 rpm, which is the rated operating point used by the connected drive during continuous motion. The shaft has a diameter and length of 19 x 40 mm, making it suitable for rigid clamping with common hubs or collars. At zero speed, the electromagnetic system can sustain 38 Nm of torque, which supports load holding and rapid acceleration from standstill. This combination of mounting size, shaft geometry, and low-speed torque suits compact axes that need direct torque transfer without a large mechanical envelope.

The motor uses resolver feedback for position information, allowing the controller to monitor rotor angle during closed-loop operation. It is supplied in a standard configuration, so it does not include custom winding or sealing changes. That layout keeps installation aligned with the usual SD mechanical outline and avoids the need to account for nonstandard mechanical features. Closed-loop feedback helps the drive correct position error during starts, stops, and reversals, which is important on indexing and handling motions. The motor is intended for applications that need stable low-speed behavior, precise positioning response, and dependable speed regulation during normal industrial duty.
