Product Description:

The SE-LB3.033.030-04.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the SE Synchronous Servo Motors series. Within automated production lines, this motor forms the electromechanical link between a servo drive and the moving load, supplying precisely timed rotation so that tools, conveyors, or gantry axes follow programmed motion profiles without slip. An integrated holding brake maintains position during power-off, allowing safe downtime in vertical or suspended installations.

In rated operation, the rotor reaches 3000 rpm, giving control systems a wide velocity span for both process speed and indexing tasks. At standstill, the motor can deliver 4.2 Nm of static torque, enough to counter moderate inertial loads before movement begins. The electromagnetic conversion factor is 1.02 Nm/A, so the servo amplifier can predict generated torque directly from commanded current. Fast current build-up is enabled by an electrical time constant of 5.8 ms, while the rotor itself responds in 7.6 ms, ensuring that speed corrections track controller outputs with minimal lag. A continuous standstill current of 4.0 A is required to hold the rated torque without overheating.

Mechanical integration is simplified by a centering diameter of 95 mm and a rectangular flange that measures 116 x 105 mm, allowing direct exchange with other motors in the same size class. The laminated steel stack and brake assembly bring the overall length to 263 mm and the mass to 9.2 kg, which can affect mounting balance and axis response. Coil parameters include a winding inductance of 60 mH and a winding resistance of 7.9 ohms, which limit current ripple and influence thermal dissipation together with the 19-minute thermal time constant. The brake operates on 24 V DC, and the Ø19 × 40 mm shaft supports straightforward coupling to gearboxes or pulleys.
