Product Description:
The LSM130-102-304-E2-0KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. In automated equipment, it converts controlled electrical energy into rotational motion that is tightly regulated by a drive, supporting precise positioning, speed holding, and rapid indexing on material-handling and assembly axes. An internal optical encoder feeds position data to the control loop so commanded motion is maintained despite load changes.
At its rated operating point, the motor supplies a continuous shaft torque of 11.5 Nm; this level can be delivered indefinitely while the windings stay within thermal limits. The shaft reaches a synchronous speed of 3000 rpm when powered by a 460 V inverter, and a 2000-line encoder gives the controller fine angular resolution. An eight-pole rotor increases the electrical frequency relative to the mechanical speed, sharpening servo response. Current capacity ranges from a stall value of 9.6 A peak to a transient maximum of 48.1 A peak, allowing the drive to overcome static friction during startup. Electromechanical conversion is characterized by a torque constant of 1.28 Nm/A and a back-EMF constant of 154 V/kRPM. Along with a 2.2 Ω winding resistance, these parameters support drive sizing and thermal analysis.
During acceleration, the motor can produce up to 52 Nm of shaft torque for short periods, giving machines additional torque for fast cycle times. A low rotor inertia of 0.00055 kg-m² minimizes settling time after direction changes, while the motor mass of 11.8 kg allows secure mounting during installation. Electrical transients are moderated by a winding inductance of 12.4 mH. Mechanical output is transmitted through a 24 mm shaft that carries an M8 × 1.25 mm thread for axial retention. The eight conductors are arranged for 460 V three-phase operation.
