Product Description:

The synchronous servo motor SE-LB3.033.030-04.019 is built by Bosch Rexroth Indramat and belongs to the SE Synchronous Servo Motors series. It serves as a rotary actuator for industrial automation axes that require accurate velocity and position control. When paired with a compatible drive, the motor delivers controlled torque to machinery without mechanical transmission backlash.

The motor mounts against a square flange that measures 116 mm across, and a precision pilot of 95 mm centers the housing on the machine frame. Rotary power exits through a ground steel shaft with a diameter of 19 mm, while the housing length of 263 mm keeps the overall package compact for multi-axis assemblies. The rotor can reach a peak speed of 6000 rpm, while normal process operation occurs at 3000 rpm to provide thermal headroom for transient motion. The motor has a mass of 9.2 kg, allowing standard lifting fixtures to support installation without overstressing mounting brackets. A 40 mm shaft extension accommodates couplings, and an M6 centering hole supports pilot tooling during setup. Signal and power conductors terminate in a circular connector that accepts 2.5 mm² cable, matching the drive’s current requirements.

Ingress protection is rated at IP67, helping the stator windings remain dry during washdown or exposure to dust. Producing continuous electromagnetic torque at standstill requires only 4.0 A, which minimizes cabinet dissipation while the axis is clamped. The holding brake uses a coil supplied with 24 V DC ±10%, allowing fail-safe restraint whenever motion is disabled. The assembly withstands mechanical shocks up to 6 g, helping protect encoder integrity on presses or pick-and-place gantries. A measured noise level of 58 dB(A) supports installation near operators without additional acoustic shielding. The interface flange uses a gasket that maintains the enclosure seal under axial loads created by the shaft projection.
