Product Description:

The SD-B3.050.030-01.000 is a brushless permanent-magnet servo motor manufactured by Bosch Rexroth Indramat for the SD Magnet Motors series. It is intended for use as a torque source in automated assembly stations, pick-and-place modules, and general positioning axes where accurate rotary motion is required. The motor converts electrical input from matched drive amplifiers into controlled shaft movement for positioning and speed regulation. Its integrated stator, rotor, and feedback interface create a compact actuator that mounts directly to machine frames and helps reduce coupling misalignment in industrial automation systems.

Its mechanical footprint is based on a 116 mm flange, which provides a standardized square mounting face for fixed machine plates and IEC planetary gearboxes. The rotor uses ferrite magnets, which provide a stable magnetic field and avoid the use of rare-earth materials. The motor has a 3000 rpm nominal speed, which matches drive controllers that operate with 200 Hz electrical frequencies. When the shaft is held at zero speed under command, the motor can resist external load with 5.0 Nm standstill torque, allowing the axis to maintain position without a separate holding brake in suitable applications. As a brushless servo motor, it uses electronic commutation instead of brushes, which eliminates brush wear and supports continuous-duty operation.

Power is delivered through a keyed shaft that follows the DIN 6885 form. The output end has a 19 mm shaft diameter and a 40 mm shaft length, so it can accept common couplings and hubs without special adapters. This shaft arrangement provides secure torque transfer to connected mechanical components during repeated indexing and positioning cycles. The dimensions are suitable for compact drive assemblies where accurate alignment and reliable shaft engagement are important.
