Product Description:

The SD-B3.050.030-00.000 is an electric motor built by Bosch Rexroth Indramat in the SD Magnet Motors series. It serves as the primary rotating element in automated machinery, where it delivers commanded torque and speed to actuate conveyors, indexing plates, or lightweight actuators under servo control. Within a closed-loop axis, torque commands from the controller are translated into repeatable motion for packaging, assembly, and test equipment. This operating role makes the motor suitable for applications that need accurate acceleration, stable running speed, and consistent response to changing load conditions.

At standstill, the rotor can apply a holding torque of 5.0 Nm, which allows the drive to maintain load position in moderate-duty applications where the load must remain in place for short periods. During continuous motion, the shaft reaches a nominal speed of 3000 rpm, which suits common servo amplifier output ranges for mid-range automation tasks that rely on fast cycle times. The front mounting interface uses a 116 mm square flange pattern, and power is transmitted through a cylindrical shaft sized at 19 x 40 mm, which supports straightforward coupling to common machine elements. Magnetic excitation is provided by ferrite permanent magnets, which give stable field strength and support predictable torque production during normal operation.

The motor uses a shaft with keyway and feather key, so torque can be transferred positively to pulleys, couplings, or gears. As a brushless servo motor, it uses electronic commutation to avoid brush wear, improve speed linearity, and reduce electrical noise during operation. The lack of brushes also reduces routine maintenance associated with mechanical commutator parts. This layout supports precise speed and position control when the motor is paired with a compatible feedback system and drive.
