SE-B4.210.050-00.000

The SE-B4.210.050-00.000 is a high-performance servo motor from the renowned Bosch Rexroth Indramat SE Synchronous Servo Motors series, engineered for demanding industrial automation environments. With a compact footprint of 80 x 398 x 200 mm and a lightweight design at just 6 kg, this motor delivers exceptional power density for space-constrained applications. It operates at a nominal current of 80 A and supports both 50/60 Hz line frequencies, ensuring global compatibility without additional configuration. Featuring a robust cross-section of conductor of 25 mm² and EMC Level Class A compliance, the SE-B4.210.050-00.000 meets rigorous electromagnetic interference standards for noisy factory floors. The unit’s maximum ambient operating temperature of 45°C combined with a minimal power loss of 25 W underscores its optimized thermal performance and energy efficiency.

In terms of technical capabilities, this servo motor boasts a torque constant (KT) of 0.64 Nm/A and a voltage constant (KE) of 68 V/1000 rpm, delivering precise torque control and stable speed regulation. Its peak current rating of 174 A at 20°C ambient ensures reliable response under sudden load surges, while the rated leakage current of 35 mA enhances safety by limiting unintended current paths. The motor’s moment of inertia (J) of 4.98 x 10^-3 kgm² is carefully optimized to balance dynamic acceleration requirements with smooth, low-vibration operation. Detailed electrical characteristics are complemented by a well-defined flange dimension of 142 mm and a robust shaft dimension of 24 x 50 mm to support high-precision coupling. Engineers will appreciate the carefully designed conductor cross-section and winding architecture, which provide low inductance and rapid current response for tight motion control loops.

Operational features focus on durability, serviceability, and continuous uptime in harsh industrial settings. The motor’s EMC Level Class A compliance guarantees minimal interference with sensitive control electronics, while the 45°C maximum temperature rating allows safe operation in elevated ambient heat. At just 25 W of power loss, the SE-B4.210.050-00.000 maintains high efficiency, reducing cooling requirements and lowering overall system energy consumption. Its compact 80 x 398 x 200 mm dimensions and 6 kg weight simplify integration into existing machinery or new designs, freeing space for ancillary components. The combination of low thermal inertia and robust materials ensures long operational life, reduced maintenance, and consistent performance under cyclic loading.

Integration into automation systems is streamlined thanks to standardized mechanical interfaces and flexible mounting options. The precision 142 mm flange and 24 x 50 mm shaft facilitate direct coupling to gearboxes, spindle heads, or rotary tables without custom adaptors. With compatibility across both 50 Hz and 60 Hz power networks and a cross-section conductor of 25 mm², this servo motor integrates seamlessly with common drive amplifiers from Bosch Rexroth Indramat or third-party manufacturers. Ideal applications include CNC machinery, packaging lines, robotics, and indexing tables where compact size, high torque density, and reliable operation are paramount.
