Product Description:

The SE-LB3.055.030-10.000 synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. Designed for direct coupling to precision gear stages or load shafts, the motor converts electrical input from a servo drive into controlled rotary motion. In automated assembly cells, packaging equipment, or indexing tables, it provides repeatable positioning and rapid speed changes while occupying a compact footprint.

The motor reaches a nominal speed of 3000 rpm, allowing machine axes to cycle quickly without exceeding mechanical limits. A static torque of 6.8 Nm is available at standstill, so the drive can hold loads firmly during dwell periods. The electromagnetic design yields a torque constant of 1.02 Nm/A, meaning each ampere of phase current produces just over one newton-meter, while a standstill current of 6.7 A sets the continuous thermal loading on the windings. Back-EMF builds in proportion to speed at 113 V/1000 rpm, giving the drive controller clear voltage feedback for commutation. Copper losses are limited by a winding resistance of 3.53 Ω, and the 2.5 mm² motor cable cross-section supports the required current without excessive voltage drop.

With a mass of 10.6 kg and an overall length of 287 mm, the unit can be mounted on compact frames while maintaining inertia suitable for mid-range loads. An electrical time constant of 8.4 ms pairs with a winding inductance of 30 mH to govern current rise behavior, enabling the drive to track high-frequency command changes without instability. Mechanical interfaces include a pilot diameter of 95 mm for centering, a 19 mm shaft diameter, and a 40 mm shaft length, and the shaft is supplied without a keyway to suit clamp-style couplings. Maximum airborne noise is limited to 58 dB(A) for operator comfort, and the specified cable area eases routing through energy chains.
