SE-B4.139.030-14.000

The Bosch Rexroth Indramat SE-B4.139.030-14.000 from the SE Synchronous Servo Motors series is a compact industrial automation solution designed for precise motion control. This servo motor operates within a 24V DC to 48V DC voltage range and delivers a continuous current of 40A, with a peak current of 73A to handle demanding dynamic loads. With a maximum mechanical speed of 7500 rpm, the SE-B4.139.030-14.000 provides fast acceleration and rapid response for high-performance positioning tasks. Its primary application lies in robotics, CNC machinery, and automated assembly lines where uniform, repeatable motion is critical.

Incorporating natural convection cooling, this servo motor maintains optimal thermal performance without additional fans or liquid-cooling systems. Feedback is provided via an incremental encoder with Hall sensors, ensuring accurate speed and position monitoring. The rotor inertia of 0.0021 kg·m² enables controlled starts and stops, reducing mechanical stress on connected drives. The compact housing weighs 3.5 kg and features an IP20 protection class, making it suitable for indoor equipment cabinets and controlled environments. The motor’s thermal time constant of 7 minutes and Insulation Class F (155°C) ensure reliable operation under sustained loads.

The SE-B4.139.030-14.000 is built to industrial mounting standards, featuring a 139 mm × 139 mm flange and a 19 mm shaft diameter for seamless integration with existing couplings and gearboxes. Rated to Vibration severity level A per IEC 60034-14, it offers enhanced durability in environments subject to mechanical vibration. Interfaces include RS232 and RS485 for versatile communication with PLCs and motion controllers. The IP20-rated enclosure and Class F insulation deliver long-term efficiency and safety within machinery enclosures. By combining high torque, precise feedback, and robust thermal management, this servo motor elevates productivity and reliability in automated production systems.
