Product Description:

The SE-LB3.075.060-10.000 is a compact synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the SE Synchronous Servo Motors series. It is intended for closed-loop motion axes where accurate velocity regulation and repeatable torque delivery are essential for pick-and-place gantries, tool spindles, or packaging stations. Its synchronous design supports controlled positioning and stable speed regulation when paired with a compatible drive.

In continuous operation, the motor reaches a nominal speed of 6000 rpm, allowing direct coupling to high-speed mechanical stages. At standstill, it can exert 8.2 Nm of torque while drawing 14 A of standstill current, allowing the drive to maintain holding torque without an external brake. The electromagnetic design provides a torque constant of 0.58 Nm/A, meaning each ampere commanded by the drive produces more than half a newton-meter of torque. During dynamic peaks, the winding can accept 84 A, which supports rapid acceleration together with a peak torque of 22 Nm. Copper losses are influenced by a winding resistance of 0.90 Ω, and the 8.7 mH inductance helps shape current rise times. The rotor-mounted tachogenerator outputs 1.8 V per 1000 rpm with a tolerance of plus or minus 5%, and the back EMF of 63 V per 1000 rpm must be considered when selecting the drive bus voltage.

The compact housing supports installation in tight machine spaces, and the mounting flange measures 116 × 105 mm. Despite its size, the rotor stores only 1.66 × 10⁻³ kg·m² of inertia, so commanded speed changes can be reached after the short 59 ms ramp-up time. Under transient loading, the motor can deliver 22.0 Nm when driven by a Sm 25/50 amplifier. The 19 × 40 mm shaft is ground for concentricity to simplify gear or pulley attachment, and the 12.8 kg housing mass also helps dissipate heat during operation. This motor is suitable for robotic wrists and linear stages that require high acceleration with minimal overshoot.
