Product Description:

The SD-B3.031.030-15.001 is a brushless servo motor manufactured by Bosch Rexroth Indramat and supplied within the SD Magnet Motors series. The unit converts electrical energy into controlled mechanical rotation for positioning axes and speed-regulated drives in automated machinery. Its design targets applications where responsive torque production and compact mounting dimensions are critical to maintaining cycle times on packaging lines, robotics cells, and material handling equipment. Within a closed-loop drive, it pairs with matching servo amplifiers to deliver repeatable motion profiles while minimizing maintenance compared with brushed designs.

During operation, the motor draws a rated phase current of 3.25 A, so drive electronics must supply this continuous value without excessive thermal rise. The electromagnetic system delivers 0.98 kW of mechanical output, which suits mid-range duties such as feeder stations or small gantries. A nominal shaft velocity of 3000 rpm sets the operating speed around which velocity control loops are tuned. Starting and low-speed holding capability is characterized by 3.1 Nm of standstill torque, enabling the axis to support inertial or gravitational loads when motion is stopped. Position and speed feedback is supplied through an integrated tacho generator, which provides an analog voltage proportional to rotational speed for real-time regulation.

The mechanical interface follows a square IEC pattern with a 116 mm flange, simplifying installation in multi-vendor assemblies. Power is transmitted through a splined shaft with dimensions of 19 × 40 mm, a size that accommodates common couplings while limiting overhang forces on the front bearing. Rotor excitation is produced by permanent magnets made from Ferrite, giving stable flux without rare-earth materials and supporting consistent performance over a wide temperature range. The motor fits modular drive systems and maintains predictable thermal behavior when mounted in confined control cabinets.
