Product Description:

The LSM100-22-454-E2-0KA is a brushless servo motor produced by Kollmorgen in the LSM Brushless Servo Motors series. Designed for closed-loop motion control, it couples a permanent-magnet rotor with electronic commutation to provide precise torque for conveyors, pick-and-place modules, and similar industrial axes. When paired with a 2000-line incremental encoder, the motor allows machine controllers to read exact shaft position and velocity, enabling repeatable indexing and reduced settling time during automated cycles.

Under continuous loading, the motor delivers 2.5 N·m of torque, while short bursts can reach a peak value of 11 N·m for acceleration or disturbance rejection. To achieve those figures, the drive may supply up to 16.3 A peak, while locked-rotor operation requires 3.3 A peak. Each ampere contributes directly to output because the torque constant is 0.82 N·m/A. Operation is intended on a 460 VAC bus, so the servo amplifier must match this voltage class and handle the motor’s eight-pole configuration to generate the correct phase sequence. A keyway shaft simplifies coupling to gearboxes or pulleys, and the rotor inertia of 0.00011 kg·m² supports fast reversals without excessive overshoot. The motor has a net weight of 4.2 kg, which keeps the assembly light enough for moving-axis mounting, and the encoder’s quadrature signals provide 8,000 counts per revolution after x4 interpolation.

Electrical behavior is further characterized by a phase inductance of 25.8 mH and a phase resistance of 10.7 Ω. Together, these values affect current rise time and copper losses that the drive’s current loop must compensate for during operation. The back EMF slope of 99 V/kRPM indicates that every 1,000 rpm generates 99 V at the terminals, which helps establish regenerative energy limits and speed setpoints. The eight-pole construction and incremental feedback support tight velocity regulation across load changes while keeping thermal dissipation within permissible limits.
