Product Description

Bosch Rexroth manufactures the SE-LB3.055.030-04.015 servo motor, known for its high dynamic response and long service life. The SE-LB3.055.030-04.015 servo motor from Bosch Rexroth Indramat is an excellent example of optimized electromechanical design in the SE Servo Motor Series. With dimensions of 80 x 398 x 200 mm and a weight of 10.6 kg, it’s made from the right materials and has the proper structure to minimize inertia and maximize dynamic response. The thermal characteristics are also impressive. With a max operating temperature of 45°C and 25 watts power loss, it’s a good heat sink, so it will be reliable and perform well even under heavy load. This is also shown by the thermal time constant of 29 minutes; it can withstand temporary overloads without significant temperature rises.

From an electrical point of view, the SE-LB3.055.030-04.015 is suitable for performance and controllability. It runs with 80 A 50/60 Hz and has a lot of torque for its size. The voltage constant of 113 V/1000 rpm gives a direct relation between motor speed and generated voltage, so it’s easy to control. The winding resistance of 3.53 Ohms and winding inductance of 30 mH make the electrical time constant 8.4 ms. Together with the mechanical time constant of 3.8 ms, it determines the response time of the motor to input signals and, therefore, the dynamic behavior and controllability in high-performance applications.

An essential aspect of industrial components is electromagnetic compatibility (EMC). The SE-LB3.055.030-04.015 has an EMC level of Class A. In environments with high EMC requirements, additional measures might be necessary to avoid electromagnetic disturbances. The motor also has safety and reliability in mind. The rated leakage current of 35 mA is kept low to minimize the risk of electric shock and to keep the operator safe. This is important in industrial environments where people can touch the motor or connected components. Wake Industrial offers a one-year guarantee on this servo motor with rare-earth magnets for increased power.
