Product Description:

The SE-B2.040.030-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat in the SE Synchronous Servo Motors series. It is intended for closed-loop industrial axes where accurate torque and speed regulation are required for motion sequencing, indexing, or point-to-point positioning. The unit converts electrical input into controlled torque for a wide range of automation tasks, and its electromagnetic design supports dynamic response while the mechanical envelope fits common automation frames.

At its nominal operating point, the rotor turns at 3000 rpm, a speed that matches drives engineered for 50 Hz or 60 Hz command frequencies. The motor can deliver a continuous static torque of 5.0 Nm at standstill, giving enough holding force for indexing tables and pick-and-place heads. This output is achieved with a continuous phase current of 4.5 A, while copper losses are influenced by a winding resistance of 6.4 Ω. A torque constant of 1.14 Nm/A relates drive current to shaft torque, which supports current-mode control loops. Magnetic energy storage is characterized by a winding inductance of 54 mH, which filters current transients and helps minimize ripple. The motor mounts on a 100 mm square flange, and its Ø14 × 30 mm keyed shaft couples directly to gear stages. Rotor inertia is 0.75 × 10⁻³ kg·m², balancing quick acceleration with stable load control.

During rapid cycles, the drive can command up to 26 A peak phase current, enabling short bursts of acceleration beyond the continuous limit. A back-EMF coefficient of 112 V/1000 rpm provides feedback to the inverter and indicates the required DC-bus level at high speed. The electrical dynamics are further shown by a time constant of 8.1 ms, so current rises to its reference quickly and settles without overshoot. For power-off safety, the integrated holding brake clamps the shaft with 3.5 Nm of torque; it engages through a 0.7 A coil supplied with 24 VDC and adds only 0.11 × 10⁻³ kg·m² to the reflected inertia.
