SE-LB3.075.030-10.000

The Bosch Rexroth Indramat SE-LB3.075.030-10.000 from the SE Synchronous Servo Motors series delivers precision motion control in industrial automation with a voltage constant of 113 V/1000 rpm and operates on a 240 V supply. Its continuous power of 4 KW is complemented by a rated current of 8.2 A and a rate load current of 5.2 A, ensuring robust torque output across demanding cycles. Designed for three-phase mains at 50/60 Hz, the motor’s winding resistance of 2.1 Ohms and winding inductance of 21 mH have been optimized for minimal electrical loss. A compact shaft size of 19 x 40 mm and a low moment of inertia of 1.66 x 10^-3 kgm2 support rapid acceleration while conserving cabinet space.

Electrical responsiveness is exceptional, with an electrical time constant of 10.2 ms and a mechanical time constant of 3.3 ms that yield fast settling times under load. Heat management is maintained via a thermal time constant of 32 min, permitting sustained peak performance and a broad overload range without thermal derating. High demagnetization strength withstands transient currents up to six times standstill values, protecting magnetic circuits during abrupt stops or voltage spikes. A rugged holding brake secures the axis in a de-energized state, engaging automatically and releasing only when 24 V DC is applied, facilitating safe maintenance and emergency stoppage.

Reliability is assured through long-life bearings rated for over 20,000 operating hours and stator windings engineered for a lifespan exceeding 70,000 hours. The integrated tachogenerator provides closed-loop speed feedback for maintenance-free operation and precise velocity control. Altogether, the SE-LB3.075.030-10.000 servo motor combines high dynamic range and thermal stability for optimal performance in packaging machinery, robotics, and high-speed indexing applications.
