Product Description:

The SE-B2.030.060-10.006 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It serves as a rotary actuator that translates controlled drive current into accurate shaft motion for positioning, feed, and spindle functions in automated machinery. When paired with a compatible Rexroth drive, the motor supplies feedback-driven speed and torque regulation that supports high-cycle assembly cells and rapid tool changers.

The electromagnetic section is optimized for fast response. A nominal speed of 6000 rpm provides continuous operating velocity when the drive frequency and the motor’s six-pole stator field are synchronized. The winding can absorb transient overloads with a peak current of 45 A, while continuous stall operation draws 7.5 A. Output torque increases in proportion to current at a torque constant of 0.42 Nm/A, and the generated back EMF follows a voltage constant of 45 V/1000 rpm. The stator’s electrical network has an inductance of 14.0 mH and a resistance of 2.25 Ω, which affect current-loop bandwidth and drive controller tuning.

The motor uses an IM B5 footless flange mounting pattern, and the flange diameter measures 100 mm. Its overall housing length is 254 mm, permitting compact mounting behind gear stages, while the smooth Ø14 × 30 mm shaft is supplied without a keyway for use with clamp couplings. The rotor’s mass moment of inertia is 0.60 × 10⁻³ kg·m², allowing quick acceleration to rated speed with modest drive torque. The motor weighs 7.6 kg, which simplifies handling during installation. Its thermal time constant is 19 min, indicating how gradually the motor temperature responds to changes in operating load. The motor can sustain a static holding torque of 3.0 Nm without exceeding its temperature limits.
