Product Description:
The LSM165-119-454-E2-2KA belongs to the LSM Brushless Servo Motors series manufactured by Kollmorgen. This rotary motor is intended for industrial automation tasks that demand responsive torque and repeatable speed control. It allows machinery controllers to translate drive commands into accurate shaft movement for indexing tables, material feeders, and multi-axis gantries. Its eight-pole rotor supports high torque density within a compact servo motor design and provides smooth operation across the available speed range.
The motor delivers a continuous output torque of 13.5 Nm without exceeding its winding temperature limits under the permitted operating conditions. It can operate at speeds up to 4500 rpm, providing the velocity needed for rapid positioning and material-handling cycles. Electrical loading during high-demand moves can reach 70.7 A peak, so the selected drive must provide sufficient current capacity at the rated bus voltage of 460 V. A torque constant of 0.87 Nm/A provides a predictable relationship between phase current and shaft torque for closed-loop regulation. The feedback device generates 2000 quadrature encoder lines, supplying incremental position data that the drive can use for accurate speed and motion control. A voltage constant of 105 V/kRPM indicates the motor’s back-electromotive-force behavior as shaft speed increases.
For brief acceleration and load changes, the motor can produce a peak torque of 51 Nm. Its continuous stall-current rating is 16.4 A peak, indicating the current associated with zero-speed thermal operation. The winding has a resistance of 0.76 Ω, which contributes to copper losses as current passes through the motor phases. Its inductance of 6.68 mH moderates the rate of current change and helps the drive regulate phase current during rapid command transitions. A 24 VDC fail-safe brake holds the load when motor power is removed, helping prevent unwanted shaft movement on stationary or vertical axes. The shaft end includes an M10 × 1.5 mm threaded section for secure attachment to compatible gearheads or couplings.
