SE-B5.440.020-10.000

Bosch Rexroth Indramat’s SE-B5.440.020-10.000 servo motor is a high-performance member of the SE Synchronous Servo Motors series engineered for industrial automation. Featuring a 400 V voltage rating and an air-cooled design, this synchronous servo motor delivers a rated power of 2 kW with an overall efficiency of 90% under nominal load conditions. The compact form factor, with overall dimensions of 300 × 200 × 400 mm and a 190 mm flange dimension, facilitates seamless integration into space-constrained machine platforms. Weighing 15 kg, the SE-B5.440.020-10.000 balances robust construction with manageable mass, simplifying installation and maintenance. Its design emphasis on thermal management and precise feedback makes it well suited for continuous operation in demanding manufacturing environments.

Technical specifications of the Bosch Rexroth Indramat SE-B5.440.020-10.000 highlight its precise electrical and mechanical parameters. The servo motor operates at a nominal speed of 2800 rpm and is rated for a continuous current of 5 A, with a current at standstill of 35 A for starting torque. The voltage rating of 400 V is compatible with standard industrial power networks at 50 Hz frequency. Winding characteristics include a winding inductance of 5.0 mH and a winding resistance of 0.26 Ω, delivering a torque constant of 1.51 Nm/A that ensures proportional torque response to current input. The electrical time constant of 19.2 ms and mechanical time constant of 6.5 ms define the motor’s dynamic response, while a thermal time constant of 40 minutes governs heat dissipation under continuous loading.

Operational features of the SE-B5.440.020-10.000 are optimized for precision motion control and high-load performance. The static torque of 44 Nm supports demanding positioning tasks, and the maximum torque of 123 Nm under peak conditions enables rapid acceleration and deceleration profiles. A moment of inertia of 18.6 kg·m² ×10⁻³ contributes to smooth motion transitions and minimal overshoot. The motor’s airflow-based cooling system maintains performance consistency and prevents thermal derating during extended duty cycles. A controlled ramp-up time of 36 ms ensures gradual acceleration without inducing mechanical stress or electrical overshoot.

System integration of the SE-B5.440.020-10.000 servo motor is streamlined via standard synchronization interfaces and compatible drives from Bosch Rexroth Indramat. Its narrow flange and standardized shaft dimensions allow direct coupling to a variety of gearboxes, couplings, and feedback devices. Applications for this series include CNC machine tools, high-speed packaging equipment, industrial robots, and automated assembly lines. The motor’s robust construction and precise specification set make it an ideal choice for system designers requiring reliable, high-accuracy motion control solutions.
