Product Description:
The SE-LB3.055.060-00.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Designed for industrial automation, the unit supplies closed-loop rotary motion to indexing stations, linear stages, and packaging equipment that require repeatable acceleration and accurate positioning. Its electromagnetic design provides high torque density while maintaining modest overall dimensions, allowing the motor to fit into compact machine frames and connect to suitable gearboxes. The motor operates with a compatible servo drive that regulates torque, speed, and position from feedback signals. This arrangement supports controlled motion under changing loads and during repeated production cycles.
The motor reaches a nominal shaft speed of 3000 rpm, providing a practical operating range for high-speed automated axes. Its electromagnetic circuit can produce a peak torque of 16.2 Nm, giving the motor short-term acceleration capability beyond its continuous static torque of 6.8 Nm. The motor draws a standstill current of 12.6 A and has an acceleration time of 28 ms, supporting brief indexing cycles when paired with an appropriately sized drive. The winding terminals accept conductors with a cross-sectional area of up to 2.5 mm², allowing secure cabling between the drive and motor. Balanced windings and rotor geometry help reduce torque ripple during controlled rotation. These electrical characteristics support responsive operation in applications that require frequent starts, stops, and changes in speed.
The laminated rotor has an inertia of 1.21 × 10⁻³ kg·m², balancing dynamic responsiveness with resistance to sudden speed changes. The motor has a mass of 10.6 kg without a holding brake, and its housing length remains within 287 mm for installation in compact enclosures. Radial alignment is provided by a 105 H8 pilot, while the square flange measures 116 mm across for secure face mounting. A 19 mm cylindrical shaft has a 40 mm projection and uses an A6 × 6 × 32 feather key to transfer torque to a coupling or gearbox. The assembly withstands shocks of up to 6 g. Service leads exit through a sealed connector block sized for the permitted cabling, helping protect the electrical connections in industrial machinery.
