Product Description:
The LSM100-46-454-M-2KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. Designed for closed-loop motion axes, the unit converts electrical input from a matched drive into controlled rotational movement for conveyors, pick-and-place heads, and other automated machinery. Its frameless permanent-magnet rotor and stator assembly are optimized for rapid acceleration, precise speed regulation, and repeatable positioning tasks common in industrial automation cells.
Under continuous load, the motor delivers 5.2 Nm of torque while maintaining a rated shaft speed of 4500 rpm. To support this operating point, the drive must supply up to 21.2 A peak during dynamic events, although steady speed holding can be achieved with the lower stall current of 6.4 A peak. The electromagnetic design produces a torque constant of 0.88 Nm/A, so current draw scales linearly with the demanded torque. A coil inductance of 12.44 mH filters switching harmonics and works with a winding resistance of 3.9 Ω to limit current ripple and heating.
For short bursts, the rotor can deliver up to 16 Nm, providing additional torque for indexing or overcoming static friction. An integral holding brake powered by 24 VDC secures the load when the drive is disabled. The eight-pole magnetic stack and multi-turn, high-resolution feedback transducer allow high servo bandwidth while reporting absolute position without homing. Mechanical inertia is limited to 0.0002 kg·m², enabling fast starts and stops, and the complete assembly with the brake weighs 7.1 kg. A threaded shaft end with an M5 × 0.8 thread and a depth of 12.5 mm simplifies coupling to external hardware. The back EMF slope of 106 V/krpm assists the drive in estimating speed for sensorless diagnostics.
