Product Description:

The Bosch Rexroth Indramat SE-LB3.055.060-04.000 is a synchronous servo motor in the SE Synchronous Servo Motors series. It serves as a compact drive element for industrial automation systems that demand fast acceleration and repeatable shaft positioning. When paired with a compatible drive controller, the motor generates controlled mechanical power for feed axes, pick-and-place heads, and other rotary applications that require high speed and consistent torque accuracy.

At standstill, the motor supplies 6.5 Nm of static torque, and the integrated holding brake can lock the shaft with 8.0 Nm of torque when power is removed. During continuous operation, the rotor can reach 6000 rpm, while a standstill current of 12.6 A establishes the continuous thermal load on the windings. The torque constant of 0.52 Nm/A indicates the torque produced per ampere of phase current. The back-EMF voltage constant is 61 V/1000 rpm, indicating how the generated voltage increases with rotor speed. A shaft measuring 19 mm in diameter and 40 mm in length transfers torque to the load through an A6 × 6 × 32 feather key, providing positive engagement with a compatible coupling or driven component.

For momentary acceleration, the windings tolerate a peak current of 76 A at 20 °C. A winding inductance of 11 mH moderates the rate of current increase, while a phase resistance of 1.03 ohms contributes to the electrical and thermal behavior of the motor. The rotor and built-in tachogenerator have a combined reflected inertia of 1.21 × 10⁻³ kg·m², supporting rapid speed changes in dynamic motion applications. The integrated brake operates from a 24 V DC supply and draws 0.8 A when energized. The motor measures 295 mm in overall length and weighs 11.3 kg, allowing its mounting space and supporting structure to be planned accurately.
