Product Description:

The SE-B5.440.020-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Designed for closed-loop motion tasks, the unit converts drive current into precise rotational torque for positioning tables, gantries, and feed axes in automated machinery. When combined with a compatible drive controller, it serves as the electromechanical actuator that moves machine tools, packaging lines, and assembly stations along programmed trajectories.

The motor has a nominal speed of 2000 rpm and a static torque rating of 52 Nm. This torque capability is maintained with a continuous standstill current of 35 A. The motor produces torque according to a constant of 1.51 Nm/A, allowing the control loop to calculate the required current precisely. Short acceleration events may draw up to 207 A, pushing the shaft toward its mechanical limit while keeping the motor within permissible temperatures. Electrical behavior is influenced by a phase inductance of 5.0 mH and a phase resistance of 0.26 Ω. The back electromotive force rises by 167 V per 1000 rpm. The housing carries an IP65 rating, protecting the motor against dust and low-pressure water jets during field installation.

The integrated brake supplies 56 Nm of holding torque and is energized from a 24 V DC supply with a coil current of 1.5 A. During rapid starts, the electromagnetic section can deliver up to 123 Nm, complementing the peak current capability noted earlier. A rotor inertia of 18.6 × 10⁻³ kg·m² helps the axis accelerate quickly while remaining stable under load. Thermal buildup is moderated by a 52-minute time constant, extending the period before the windings reach their temperature limit. The smooth shaft is supplied without a keyway or feather key, allowing the use of clamp couplings while reducing imbalance at speed and simplifying assembly.
