Product Description:

The XSM130-73-404-S-0AA servo motor is produced by Kollmorgen as part of the XSM Centurion Servo Motors series. Designed for precision positioning tasks in automated machinery, it converts drive commands into rapid, repeatable rotary motion for indexing tables, pick-and-place heads, and light gantries. The unit uses the manufacturer’s 130 frame, allowing it to connect to compatible IEC or NEMA gear reducers without additional adapter plates. Its compact mechanical arrangement supports installation where controlled acceleration and accurate shaft positioning are required.

The motor provides a continuous torque of 8.2 Nm while the windings draw a continuous stall current of 9.9 A. Its torque constant is 0.95 Nm/A, providing a predictable relationship between supplied current and generated torque. A rated speed of 4000 rpm supports rapid machine cycles, while the back electromotive force increases with speed according to a voltage constant of 115 V/krpm. The motor operates from a 460 V supply and uses eight poles to provide smooth commutation. SinCos feedback supplies position information to the servo drive for closed-loop motion control. The motor has no brake, so the drive must provide holding torque when the axis is stationary.

The motor can produce a peak torque of 20.3 Nm during acceleration or brief shock loads. Its rotor inertia is 0.00041 kg-m², allowing the drive to command rapid changes in speed with limited resistance from the rotating assembly. The winding has an inductance of 18 mH, which influences the current rise time during dynamic operation. Its winding resistance is 2.0 ohms, contributing to the copper losses generated under load. The insulation has a dielectric withstand rating of 2350 V, and the stator package weighs 7.3 kg. A smooth shaft without a keyway works with clamp-style couplings and reduces movement between the shaft and coupling surfaces. The remaining motor features use the standard design options available for this model.
