Product Description:

The SE-B5.570.030-04.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. Intended for closed-loop industrial drives, the unit converts three-phase power from a matched inverter into controlled rotary motion. By generating precise torque and velocity, it supports positioning tasks, indexing tables, and feed axes where repeatability and fast dynamic response are required. Its flange and shaft geometry follow standardized dimensions for straightforward mechanical integration.

Under rated conditions, the motor delivers 63 Nm of static torque at the shaft, indicating the continuous load it can hold without exceeding its temperature limits. At the synchronous speed of 3000 rpm, this torque provides stable power for process machinery. A torque constant of 0.96 Nm/A links phase current to mechanical output, enabling the drive to calculate torque demand in real time. Momentary overloads draw a peak current of 369 A, while sustained standstill operation uses 62 A. The copper windings have a resistance of 0.09 Ω. Combined with an inductance of 2.2 mH and a mechanical time constant of 2.1 ms, this low impedance permits rapid current changes while limiting electrical noise.

Short-term acceleration capability reaches a maximum torque of 138 Nm, allowing the axis to overcome sudden increases in inertia. The rotor has a moment of inertia of 23.6 × 10⁻³ kg·m², which moderates speed changes so positioning remains smooth. Thermal buildup is characterized by a time constant of 52 min, giving the motor substantial time to stabilize at its operating temperature. A voltage constant of 113 V/1000 rpm governs back electromotive force, while the tachogenerator supplies 2.7 V/1000 rpm with ±5% accuracy for analog speed loops. Current dynamics follow an electrical time constant of 23.1 ms. A 190 mm flange and a Ø32 × 58 mm shaft support installation with standard couplings.
