Product Description:

The SE-LB3.033.030-00.015 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It is intended to convert electrical power into precise rotary motion for positioning or velocity control tasks in automated machinery such as pick-and-place axes, tool changers, or packaging stations. Closed-loop drives that pair this motor with a compatible controller can regulate speed and torque in real time, allowing repeatable motion profiles and reduced mechanical wear compared with open-loop solutions.

The motor delivers a nominal speed of 3000 rpm, which is the shaft velocity that can be maintained continuously under rated conditions. At standstill, it can hold a load with 4.2 Nm of torque while drawing a standstill current of 4.1 A. Torque production per ampere is characterized by a torque constant of 1.02 Nm/A, which aids drive sizing when peak demands must be calculated. Rapid current rise is supported by an electrical time constant of 7.6 ms, allowing fast control loops for dynamic indexing. Copper losses across the stator are affected by a winding resistance of 7.9 Ω, a parameter that influences thermal loading during continuous operation.

The A-flange carries an ingress protection rating of IP67, and the A-side is sealed with a dry-running lip to block coolant or dust from entering the bearings. Rotor inertia is 0.81 × 10⁻³ kg·m², providing a balance between quick acceleration and load stability. The back electromotive force is 109 V/1000 rpm, matching the motor to medium-voltage servo inverters. Overall mass is 8.5 kg, and the housing length does not exceed 256 mm, easing installation in confined machine spaces. A thermal time constant of 19 minutes indicates the rate at which the winding temperature approaches a steady state. A shaft measuring 19 mm in diameter and 40 mm in length transmits power to couplings or gearheads without additional adapters.
