Product Description:

The SD-B3.031-030-14.000 is a brushless servo motor manufactured by Bosch Rexroth Indramat and supplied within the SD Magnet Motors series. This rotary unit converts electrical power into controlled torque and speed for positioning axes and velocity loops in industrial automation. Paired with the designated SM 5/10-T servo module, it fits into multi-axis drive assemblies where fast response and repeatable motion are required. Its aluminum housing supports convection cooling and provides IP protection suited to general machinery cabinets. The brushless design also reduces wear at the commutation system, which helps the motor maintain stable operation in equipment that starts, stops, and reverses frequently.

At its rated operating point, the motor reaches 3000 rpm, which suits applications that need moderate but accurate rotational speed. The thermal design supports a continuous phase current of 3.25 A, allowing steady operation without excessive heat buildup when the drive is matched correctly. An integrated holding brake draws 0.65 A when energized and helps hold the axis at standstill when motion must stop in a controlled way. The brake circuit includes a resistance of 8.2 ohms and uses a nominal control voltage of 24 V DC, so it can be supplied from common control power sources found in industrial panels. This arrangement is useful where the motor must remain in position during pauses, vertical motion, or power-off holding.

The feedback system uses a ROD426 incremental encoder, which supplies position signals to the controller for closed-loop motion control. Mechanical installation is based on a 116 mm square flange and a cylindrical shaft measuring 19 mm in diameter by 40 mm in length, which supports straightforward coupling to compatible machine elements. Rotor flux is produced by permanent Ferrite magnets, giving the motor stable magnetic behavior across normal operating temperatures. The holding brake can absorb at least 57 Ws of kinetic energy during emergency stopping. TTL-compatible encoder signals help the connected control system process speed and position feedback with clear digital transitions.
