Product Description:

The SE-B5.440.030-04.000 is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied under the SE Synchronous Servo Motors series. The unit converts electrical input from a compatible drive into controlled mechanical rotation, allowing machinery to index, accelerate, or hold position with high accuracy. Its keyed shaft measures Ø32 × 58 mm, and the motor has an overall length of 437 mm. This arrangement allows direct coupling to gearboxes or belt pulleys in packaging cells, pick-and-place stations, and other industrial automation axes.

During continuous operation, the motor reaches a nominal speed of 3000 rpm, enabling drive systems to synchronize linear or rotary tooling without overshoot. At standstill, it can deliver a static torque of 51 Nm, so vertical loads remain supported when motion is paused. Supplying this torque requires a continuous phase current of 47 A, so the connected drive must provide sufficient current capacity. The relationship between winding current and torque is represented by a torque constant of 1.09 Nm/A, providing predictable output under vector control. A winding inductance of 3.3 mH limits current ripple and supports precise current-loop regulation.

For dynamic cycles, the motor can accept a peak current of up to 279 A, allowing rapid acceleration before thermal limits are reached. The integrated holding brake produces 56 Nm of braking torque to secure the shaft whenever motor power is removed. The brake draws 1.5 A from a 24 V ±10% supply. A rotor inertia of 18.6 × 10⁻³ kg·m² balances responsiveness with load stability, while the back-EMF constant of 120 V/1000 rpm assists the drive in estimating speed through voltage sensing. The motor has a mass of 45 kg and uses a keyed shaft with a feather key for rigid torque transmission without additional shaft-locking devices.
