Product Description:
The SD-B4.180.020-00.000 is a magnet-excited brushless servo motor manufactured by Bosch Rexroth Indramat in the SD Magnet Motors series. In automated production cells, it supplies regulated torque and speed so that positioning tables, feed axes, and auxiliary drives can follow motion commands from a servo amplifier without mechanical backlash. The motor is intended for closed-loop operation, where commanded current is converted into predictable rotary motion for indexing, synchronized feed movement, and repeatable start-stop cycles. Electronic commutation eliminates brush wear, and the motor uses an IEC-compliant flange and standard shaft geometry for installation on machines that accept common motor interfaces.
The motor develops a standstill torque of 18.0 Nm, which supports energized holding at zero speed for vertical loads or pressing duties. Its nominal operating point is 2000 rpm, a speed that balances dynamic response with continuous-duty thermal limits. A rotor built with Ferrite magnets provides stable magnetic flux without rare-earth material. Mechanical coupling is handled by a shaft that measures 24 × 50 mm, giving standard hubs enough engagement length for secure torque transfer. The square mounting interface uses a 142 mm flange, which fits many mid-frame gearboxes and bearing blocks used in modular machines. This combination of shaft and flange dimensions supports straightforward alignment with couplings and other drive components.
The motor uses a shaft with keyway and featherkey, which helps prevent torsional slip during repeated acceleration and indexing cycles. Because the unit is a brushless servo motor, no brush replacement interval is required during normal operation. This arrangement supports precise torque transmission and stable response during frequent speed changes. The housing and interface layout are suited to general industrial machinery where compact servo drives are used for rotary or linear axis control. It is well suited to applications that require consistent acceleration, controlled holding, and repeatable motion over long production runs.
