SE-B4.130.030-04.000

The Bosch Rexroth Indramat SE-B4.130.030-04.000 servo motor is a high-performance member of the SE Synchronous Servo Motors series, engineered for demanding industrial automation tasks. It delivers rapid dynamic response with a maximum rotational speed of 5000 rpm and precise torque control, offering a static torque of 30 Nm under steady-state conditions. Weighing just 6 kg, this compact unit minimizes system inertia while providing robust mechanical power. Its low thermal losses, with a power loss of 25 W, contribute to sustained operation in continuous-motion applications. The design integrates advanced electromagnetic structures to ensure efficient energy conversion and reliable performance across a wide range of loads.

The motor’s physical and electrical characteristics are optimized for seamless integration. The frame measures 80 x 398 x 200 mm, with a flange diameter of 142 mm to accommodate standard mounting interfaces. An internal conductor cross-section of 25 mm² supports an operational current of 80 A, while the current at standstill of 18 A limits residual magnetization effects. The unit operates on standard 50/60 Hz supply and features a voltage constant of 68 V/1000 rpm for predictable voltage-to-speed scaling. Thermal management is characterized by a mechanical time constant of 4.4 ms, enabling rapid torque response, and a controlled ramp-up time of 60 ms for smooth acceleration profiles.

Operational resilience is reinforced by an EMC level of Class A rating, which ensures compliance with industrial electromagnetic compatibility standards. The rotor and stator assemblies sustain ambient temperatures up to 45°C without derating, supported by optimized heat dissipation pathways. A rated leakage current of 35 mA ensures safety under fault conditions, while the robust insulation system maintains dielectric integrity. The motor’s low inertia design, combined with precise current regulation, yields consistent torque output and minimizes overshoot during transient load changes. These attributes render the SE-B4.130.030-04.000 highly suitable for continuous-duty cycles and high-frequency positioning tasks.

System integration is streamlined through compatibility with Bosch Rexroth Indramat SM series drives, offering advanced servo control algorithms and real-time feedback loops. The servo motor’s compact footprint and standard interface dimensions facilitate retrofitting into existing machine architectures. Target applications include precision CNC machining, robotic arm actuation, packaging machinery, and high-speed assembly lines where space constraints and operational reliability are critical. The SE-B4.130.030-04.000 sets a benchmark for performance, efficiency, and integration flexibility in modern industrial automation systems.
