Product Description:

The SD-B4.140.020.01.000 is a brushless servo motor built by Bosch Rexroth Indramat within the SD Magnet Motors series. This electromechanical unit converts commanded electrical input into controlled rotary motion for positioning, feeding, or indexing tasks in automated machinery. Its brushless design reduces maintenance and supports precise torque control that is essential for CNC axes, packaging drives, and material-handling stations. Its compact dimensions allow installation inside tight drive compartments, and standard mounting interfaces simplify mechanical integration with gearboxes or direct-drive couplings. This layout also supports smooth response during repeated start-stop cycles and stable low-speed motion where accurate positioning is required.

The motor uses a flange that measures 142 mm, providing a standardized bolt circle for direct attachment to machine frames. Its rotor carries Ferrite magnets, giving a stable magnetic field and consistent performance across normal operating temperatures. Under rated conditions, the shaft reaches a nominal speed of 2000 rpm, which suits velocity matching with servo amplifiers and feedback encoders. At standstill, it provides 14.0 Nm of continuous torque, so the axis can hold workpieces without auxiliary brakes. Power transmission is handled through a cylindrical shaft sized Ø 24 × 50 mm, a dimension that fits common keyways and clamping hubs in modular automation assemblies.

The motor uses standard mounting points for straightforward alignment with compatible machine interfaces. It is supplied in a plain configuration without auxiliary sensors, brakes, or non-standard sealing. With a housing identified as frame 140, the motor suits drives sized for mid-range inertia and thermal loading. This arrangement helps keep axis layouts consistent in machines that use the same motor family.
