SE-LB3.055.030-04.015

The Bosch Rexroth Indramat SE-LB3.055.030-04.015 servo motor from the SE Synchronous Servo Motors series delivers a compact, high-performance solution for precision motion control in industrial automation. This device combines a robust electromechanical design with a lightweight housing, weighing just 10.6 kg and occupying 116 x 287 x 40 mm of installation space. Engineered to maintain stable operation up to a maximum temperature of 45°C and dissipate 25 W of power loss, the SE-LB3.055.030-04.015 ensures reliable performance under sustained load. Its design emphasizes both dynamic response and longevity, positioning it as a versatile component for high-speed and high-precision applications.

The SE-LB3.055.030-04.015 features a voltage constant of 113 V/1000 rpm and operates on a frequency of 50/60 Hz with a rated current of 80 A, enabling precise speed-to-voltage translation and controllable torque output. The winding system presents a resistance of 3.53 Ohm and an inductance of 30 mH, resulting in an electrical time constant of 8.4 ms that supports rapid current transitions. The mechanical time constant of 3.8 ms further contributes to the motor’s swift dynamic response, while a thermal time constant of 29 min allows the motor to withstand temporary overloads with minimal temperature rise. The conductor cross-section of 25 mm² ensures efficient current carrying capacity, and the rated leakage current of 35 mA maintains safety compliance in industrial environments.

Operational capabilities are enhanced by an EMC Level Class A rating, providing baseline electromagnetic compatibility for integration into complex systems. The motor’s low inertia and optimized rotor design reduce overshoot and improve settling times in high-acceleration profiles. With a continuous power loss of 25 W and stable performance up to 45°C, the SE-LB3.055.030-04.015 supports continuous-duty operation in packaging, robotics, and assembly machinery. Its compact form factor and reliable thermal management minimize downtime and simplify maintenance schedules in automated production lines.

The SE-LB3.055.030-04.015 integrates seamlessly with standard Bosch Rexroth Indramat servo drives and controllers, facilitating rapid commissioning and system tuning. Its compatibility with digital feedback systems and industry-standard communication protocols ensures straightforward incorporation into existing control architectures. Target applications include industrial robotics, CNC tooling, packaging systems, and any high-precision motion platform where space constraints and rapid dynamic response are critical.
