Product Description:

The SE-LB3.033.030-00.000 is a synchronous servo motor from Bosch Rexroth Indramat's SE Synchronous Servo Motors series. It converts regulated three-phase current into commanded shaft rotation for positioning, indexing, and speed control tasks in automated packaging, assembly, and material-handling machines. This operating principle helps the axis respond accurately to frequent starts, stops, and reversals. A metric shaft interface simplifies alignment with gearboxes or pulleys, and the compact outline helps the unit fit into dense multi-axis frames.

At a 3000 rpm nominal speed, the rotor stays in synchronism with the applied electrical frequency, giving stable velocity for cyclic machine sequences. The motor supplies 4.2 Nm of static torque during standstill and can reach 9.1 Nm under short-term load peaks, allowing the axis to overcome friction or acceleration demands without stalling. Torque production scales with current, and the 1.02 Nm/A torque constant links commanded current from the drive to mechanical output. During rapid acceleration, the winding can accept 24 A peak current, while continuous holding conditions call for 4.0 A standstill current. These currents circulate through coils with 60 mH of inductance, which shapes current rise time and supports drive tuning. Mechanically, the Ø19 × 40 mm shaft uses an A6 × 6 × 32 feather key, and the centering diameter of Ø95 j6 seats the housing concentrically on the mounting surface.

The motor has a 112 V/1000 rpm voltage constant, which helps the drive estimate speed and set voltage limits. With a total 8.5 kg mass and an overall length of 256 mm, the unit adds moderate inertial load to compact axes. Copper losses are influenced by a 7.9 Ω winding resistance, so heat generation remains manageable when the servo holds position for extended periods. The overall length also affects the clearance needed behind the mounting face in compact machine sections.
