SE-LB3.055.030-04.000

The Bosch Rexroth Indramat SE-LB3.055.030-04.000 from the SE Synchronous Servo Motors series delivers precise motion control with a nominal speed of 3000 rpm and a maximum torque of 16.2 Nm (SM=10/20). Featuring a current at standstill of 6.7 A and a static torque of 6.8 Nm, this highly responsive servo motor is engineered for demanding industrial automation applications. Its robust peak current at θambient = 20°C of 40 A ensures the delivery of short-duration torque peaks without performance degradation. Compact and efficient, the unit is optimized for seamless integration into machinery with stringent space and power requirements.

With a rapid ramp-up time of 27 ms to reach nominal speed, the SE-LB3.055.030-04.000 achieves swift acceleration and minimal cycle times. The torque constant of 1.02 Nm/A (θambient = 40°C; Δθw = 105K) assures linear translation of electrical input into mechanical output, while the voltage constant of 113 V/1000 rpm provides stable back-EMF characteristics across varying loads. Precision winding design lowers thermal buildup, complemented by a winding inductance of 30 mH that mitigates current ripple and enhances control fidelity. This blend of electrical and mechanical traits positions the motor as a high-performance solution for synchronizing complex axes and multi-drive systems.

Durability and control are further supported by a low winding resistance of 3.53 Ohm (θw = 20°C), reducing energy losses and improving thermal efficiency under continuous operation. The SE-LB3.055.030-04.000’s combination of high torque density, fast electrical response, and robust current handling makes it an ideal choice for industrial automation tasks requiring rapid position correction and sustained load handling. Its technical footprint ensures long-term reliability in high-demand environments, enabling designers to achieve precise, repeatable motion with minimal downtime.
