Product Description:
The LSM130-102-304-S-2KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. The motor is built for precision motion axes in packaging lines, electronic assembly machines, and light machining centers. When paired with a Kollmorgen servo drive, it converts three-phase electrical power into tightly regulated torque, enabling accurate position, velocity, and acceleration control in industrial automation cells. Its design includes an internal holding brake and high-resolution feedback to support secure positioning and fine interpolation.
The integral brake releases at 24 VDC, allowing the shaft to move when commanded. The motor supplies a continuous torque of 11.5 Nm while remaining within its rated temperature range, and the windings accept a peak current of up to 48.1 A for transient loads. The overall body length, including the brake, is 437 mm, and the assembled unit weighs 13 kg. These values affect the required installation space and the counterbalance requirements of gantry systems. High-resolution sine-cosine feedback transmits precise rotor angle data to the drive. The stator has an inductance of 12.4 mH and a resistance of 2.2 Ω, which the drive uses for current-loop tuning.
Dynamic performance is supported by a peak torque capability of 52 Nm, allowing rapid acceleration toward the rated speed of 3000 rpm. The eight-pole rotor has an inertia of 0.00063 kg·m², supporting fast directional changes with limited overshoot. The electromagnetic design provides a torque constant of 1.28 Nm/A, while the corresponding voltage constant is 154 V/kRPM. These values relate current commands to mechanical output and establish back electromotive force levels during regenerative braking. The shaft has an M8 × 1.25 thread with a depth of 19 mm, providing a secure connection for compatible pulleys, couplings, or gearboxes.
