Product Description:

The SE-LB3.075.060-10.100 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Designed for closed-loop drive systems, the motor supplies controlled rotary motion for automated handling units, indexing tables, and fast tool changers. Its electrical commutation and integrated feedback interface allow the connected drive controller to command rapid accelerations and decelerations while sustaining repeatable positioning accuracy in demanding industrial duty cycles.

Under rated conditions, the rotor can maintain a shaft speed of 6000 rpm, giving high linear throughput when paired with appropriate gearing. The motor delivers a maximum cyclic torque of 22.0 Nm, while static holding capability is 8.2 Nm and continuous standstill current is 14 A. Transient overloads are handled by a peak phase current of 84 A. The torque constant is 0.58 Nm/A, so each ampere of drive current produces just over half a newton-meter of torque. The back EMF at speed follows a voltage constant of 63 V/1000 rpm, which the controller uses to estimate commutation voltage and support field-oriented control. These values support rapid start-stop sequences and short-cycle positioning in closed-loop motion systems that require responsive torque control and stable speed regulation.

The motor has a long construction and measures 319 mm overall without a brake, while its mass is 12.8 kg. This size helps it fit compactly on light to medium-load axes where mounting space is limited. A low rotor inertia of 1.66 ×10⁻³ kg·m² supports fast directional reversals with limited servo gain adjustment. Stator parameters include a winding inductance of 8.7 mH and a resistance of 0.90 Ω, which influence current ripple and thermal rise during continuous duty. The drive-end plate is oil-tight for integration in lubricated gear stages, and the output shaft is Ø19 × 40 mm without a keyway, allowing clamp or shrink-fit couplings where zero backlash is required.
