Product Description:

The SD-B4.092.020-00 000 is a servo motor produced by Bosch Rexroth Indramat within the SD Magnet Motors series. It converts drive power from a matched controller into rotational motion for indexing tables, pick-and-place axes, and similar positioning stages used in automated production lines. The motor’s electromagnetic design lets it deliver commanded torque without brush wear, making it suitable for continuous industrial duty where precise velocity control is required. This operating concept supports stable speed regulation and repeatable positioning in automated machinery.

The unit reaches a nominal speed of 2000 rpm, allowing the system to run repeatable motion profiles while staying within the thermal limits of the winding set. At standstill, it can hold a load with 9.2 Nm of continuous torque, which is useful for vertical or high-inertia axes during dwell periods. Its mounting interface uses a square flange that measures 142 mm across, matching common gearbox or machine frames in this torque class. The output shaft is machined to Ø 24 × 50 mm, providing enough contact area for keyed couplings without excessive overhang load. Rotor excitation is supplied by permanent magnets made of Ferrite, so the motor maintains magnetic stability over a wide operating temperature range.

Mechanical connection is simplified by a shaft with keyway and feather key, allowing pulleys or couplers to be secured without custom adapters. Internally, the stator and rotor geometry classify the device as a brushless servo motor, which eliminates commutator maintenance and supports higher switching frequencies in the associated drive. The standard configuration is intended for applications that do not require added cooling jackets, alternate feedback arrangements, or extra sealing features. This layout keeps the motor focused on general industrial motion tasks where dependable torque delivery and straightforward integration are important.
