Product Description:
Bosch Rexroth Indramat manufactures the SE-LB3.095.030-04.000, a synchronous servo motor within the SE Synchronous Servo Motors series. The unit converts drive commands into precise rotational motion for positioning axes, feeders, and similar equipment in automated production cells. Its integrated electromagnetic brake operates from a 24 V DC supply and clamps the shaft when power is removed, keeping vertical or suspended loads stationary.
The shaft can be directly coupled through its Ø19 × 40 mm interface, while a standstill current of 10.5 A keeps the rotor magnetically centered under load. Continuous operation reaches a nominal speed of 3000 rpm and is supported by a torque constant of 1.10 Nm/A, so each ampere from the servo drive produces a predictable increment of output torque. The motor provides a static torque of 11.6 Nm at zero speed, which supports applications where the axis must hold its position without motion. Dynamic behavior is influenced by an electrical time constant of 10.8 ms and a mechanical time constant of 2.8 ms. These values indicate how quickly current builds in the windings and how rapidly the rotor responds. Peak acceleration events draw up to 63 A, and the 1.68 Ω winding resistance affects voltage demand during these surges.
Installation allowances include a maximum overall length of 359 mm with the brake fitted, and the assembly has a mass of 15.6 kg, which should be considered when sizing mounting brackets or linear slides. The brake provides 25 Nm of holding torque to secure static loads when motor torque is unavailable. Back electromotive force rises linearly according to a voltage constant of 118 V/1000 rpm, allowing the drive electronics to estimate speed from the generated voltage. The laminated stator stores magnetic energy through a winding inductance of 18 mH, which filters current ripple and affects control-loop tuning. The copper and steel reach thermal equilibrium after a thermal time constant of 35 min, permitting intermittent overloads without an immediate rise to the final operating temperature.
