Product Description:

The SE-LB3.095.030-00.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. In industrial automation, it functions as a drive element for positioning tables, pick-and-place axes, and other motion tasks that demand closed-loop control of speed and torque. Its operating profile suits machines that require repeatable acceleration, accurate stopping, and stable servo response over frequent duty cycles. Because it is used in closed-loop motion systems, the motor can respond quickly to load changes while maintaining consistent rotational behavior during commanded moves.

At its nominal speed of 3000 rpm, the rotor supports steady operation in mid-range motion applications. The motor reaches a maximum shaft torque of 18.4 Nm, and its static holding capability without rotation is 11.6 Nm. A torque constant of 1.10 Nm/A links developed torque to armature current, so the drive draws 10.5 A at standstill and can rise to 63 A during momentary peaks. With a winding inductance of 18 mH and an electrical time constant of 10.8 ms, current rise remains controlled while still supporting responsive indexing. The pilot diameter of Ø95 j6 centers the housing, and the Ø19 k5 × 40 mm shaft transmits power through keyed couplings for secure torque transfer.

A rotor inertia of 2.07 × 10⁻³ kg·m² balances quick speed changes with stable mechanical response, and the total mass of 14.9 kg adds stiffness without placing excessive load on the mounting structure. Overall body length is 351 mm, which helps the motor fit compact machine layouts while still allowing space for cable bends and internal active components. For back-EMF prediction, the drive can use the voltage constant of 118 V/1000 rpm together with the phase resistance of 1.68 Ω to estimate generated voltage and current behavior during deceleration. These values also help describe the motor’s electrical response during rapid speed changes and regenerative operating conditions.
