Product Description:

The LSM130-102-304-S-0KA is a brushless servo motor manufactured by Kollmorgen within the LSM Brushless Servo Motors series. Designed for closed-loop automation axes, the unit converts electrical drive commands into precise rotary motion for positioning tables, feeders, and other factory equipment. Its electromagnetic construction, matched to an eight-pole rotor, allows rapid acceleration while maintaining tight velocity regulation. Direct flange mounting and a standard shaft interface simplify integration with gearheads or couplings across a range of machinery.

Under continuous duty, the motor supplies 11.5 Nm of torque at its rated shaft speed. During rapid indexing or overload events, the available torque rises to 52 Nm. The shaft can rotate at up to 3000 rpm, a speed matched to the eight-pole magnetic design for low cogging. At this operating point, the bearing set tolerates a radial load of 58 kg. Drive sizing is aided by a torque constant of 1.28 Nm/A, meaning every ampere of phase current produces that level of torque. A back-EMF constant of 154 V/krpm indicates the voltage generated in relation to rotational speed. The 24 mm diameter shaft is finished with an M8 × 1.25 mm center thread for drawbar or encoder fixture attachment.

Peak motion transients draw up to 48.1 A peak, while the current under stall conditions is 9.6 A peak; these values support proper drive amplifier selection. The stator windings have 2.2 ohms of phase resistance and 12.4 mH of inductance, which influence current rise time and the selection of suitable pulse-width modulation carrier settings. Dynamic response is supported by a rotor inertia of 0.00055 kg·m², permitting fast speed changes without requiring excessive controller gain. The motor weighs 11.8 kg and measures 358 mm in overall length, which are important considerations for gantry payload calculations and machine layout. These physical characteristics also affect mounting support requirements and the available clearance around adjacent components.
