Product Description:

The SE-B3.095.030-00.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Intended for closed-loop positioning and velocity control, the unit converts drive current into accurately regulated mechanical rotation for packaging lines, handling gantries, and similar automated assemblies. Its synchronous design supports stable speed regulation and repeatable positioning during repeated motion cycles.

At a nominal speed of 3000 rpm, the rotor reaches application velocity without requiring gear reduction while maintaining magnetic synchrony. During hold or low-speed feed, it delivers 11.6 Nm of static torque, keeping loads fixed without external brakes. Short bursts of acceleration draw a peak phase current of 63 A, which is well above the 10.5 A standstill value. Current rise is governed by an electrical time constant of 10.8 ms, and rotor speed responds within a mechanical time constant of 2.8 ms. The 2.07 × 10^-3 kg·m² rotor inertia limits overshoot, while a Ø19 × 40 mm shaft coupled through an A6 × 6 × 32 feather key provides positive torque transfer. The stator offers 18 mH of winding inductance, 1.68 Ω of resistance, and a back-EMF constant of 118 V/1000 rpm for compatibility with standard Rexroth drives.

Overall length is restricted to 320 mm for cabinet integration, and the electromagnetic stack can generate up to 18.4 Nm during intermittent peaks. Continuous torque scales with a constant of 1.10 Nm/A, which simplifies drive sizing calculations. The motor housing weighs 14.5 kg, adding thermal mass that works with a rated thermal time constant of 35 min to slow temperature rise under cyclic loading. These values establish the allowable load profile, installation clearance, and duty cycle limits used for servo axes in automated machinery.
